             Dynamically analyze the changes of ocular axial length of different types of myopia
                                             WU gang-yue HUANG tang-qin.Jinhua Eye Hospital, Jinhua 321000


    ABSTRACT
    Objective:Dynamically analyze the changes of ocular axial length of different types of myopia(low Myopia group and moderate myopia group, low age group and high age group) after orthokeratology.
    Methods:Select 63 adolescents of wearing MCT Tech Design ortho-k lens in our hospital from 2009 to 2012,male 28, female 35, a total of 121 eyes, ranging in age from 8 to 14 years old,diopter degree≤ -6.00D, with-the-rule astigmatism≤ -1.50D, against-the-rule astigmatism≤-0.75D. To observe the changes of ocular axis after 1 week, 1 month, 3 months, 6 months, 12 months, 18 months, 24 months of wearing Ortho-K contact lens through overnight wear. The volunteers were divided into 4 groups: low myopia group ( the Diopter degree≤ -3.00 D ) and moderate myopia group (-3.00D ~ -6.00 D ); low age group ( 8 to 10 years old ) and aged group( 11~ 14 years old ). This grouping was according to the degree of myopia and age.
    Results:The growth of ocular axis after six months of wearing Ortho-K was statistically significant compared with unwearing ( t=4.68, P<0.05 ). The difference between ocular axial growth of the Moderate myopia group and the low myopia group after wearing a month later was statistically significant ( t=3.4, P<0.05 ), the axial growth of Moderate myopia group was slow, the axial growth between the low age group and the high age group had no significant difference(P>0.05).
    Conclusions:The effect of wearing MCT Tech ortho-k contact lens of controlling myopia is better for Moderate myopia than low myopia, while the factor of age has no effect on controlling myopia.
    【Key words】   Orthokeratology ; myopia control ; axial length  
     
    Along with the increasing incidence of juvenile myopia, and the appearance in younger ages, more and ophthalmologists select effective way to control myopia. Orthokeratology is accepted by ophthalmologist in both domestic and abroad, but we clinically found that for ortho-k lens, its effect is uneven for different patients. For some wearers, their eye axis changes is little for a year or two years later, but for some wears, after a few months later, the axial became significantly longer and whether there is any objective factors, such as age, diopter, and so on? Now, we will show the treatment effect and the axis reports from our hospital for 3 years.


    SUBJECTS & METHODS
    1.Clinical Data
      Selected from 63 cases teenagers who firstly wear Ortho-k lenses for over 2 years in 2009 to 2012. There are totally 121 eyes and male 28 cases and female 35 cases. The first wearing is from 8 ~ 14 years old, and the average age is 10.77 ± 1.90. The diopter of spherical power is - 6.00 D or less, the inverse rule astigmatism is - 1.50 DC, and the rule astigmatism is - 0.75 DC or less.
    According to the degree of myopia, the wearers were divided into low myopia group whose spherical power was - 3.00 D or less and there were totally 68 eyes;
    Moderate myopia group whose spherical power was 3.00 D ~ 6.00 D, and there were totally 53;
    According to the first wearing age, there was young age group 8-10 years old which had totally 62 eyes;
    And older age group which is in 11 ~ 14 years old and totally 59 eyes.
    2.Methods
      (1) According to the standard fitting process of Ortho-k lens, all cases include the naked eye eyesight test, medical optometry correction, corneal topography curvature test, IOL Master, corneal thickness test, eye disease screening programme, such as slit lamp examination, non-contact intraocular pressure, retinal examination. 
    (2) After excluding all contraindications, customized the lens according to the results of the corneal topographic map and the result of medical optometry.
    (3) Guide patients to wear and maintain lens, and ask patients strictly under the wearing time: wear 8 ~ 10 hours at night. Discuss with parents to and pay special attention to the clean and health. After wearing lens 1 day, 1 week, 1 month, 3 months, 6 months, 12 months, 18 months and 24 months, to do the recheck. The contents are the eyesight, eye axis, corneal topographic map, diopter, corneal thickness, intraocular pressure; Palpebral conjunctiva and bulbar conjunctiva, cornea transparency, damage, and phenomenons such as tears. If you feel unwell or have any abnormal, do the timely treatment, and stop wearing for a few days which are determined by the physician.
    3. Materials & Equipment
      The material of the lens is the third generation of Ortho-k lens, Boston XO whose DK value is 100. The lens is provided by E&E company in the United States; the lens is use reverse geometric four arcs design, and it total diameter is 9.80 ~ 11.60 mm. The lens is designed by Professor Wang in Shanghai Furen ophthalmic hospital. This lens is Ortho-k Leans designed by new digital model technology, and we also call it Rigid Gas Permeable Contact Lens for Orthokeratology. The lens greatly improved the traditional Orthokeratology, mainly used corneal shape, and make the cornea gradually to a more rational deformation, and finally help us to achieve the effect of safe vision correction, Rigid Gas Permeable Contact Lens for Orthokeratology, MCT technology provided by Wuhan Web Science and Technology Development Co., LTD and the measurement of eye axis is by IOL-master optical measurement instrument from Chua′s Company.
    4. Statistical Methods
    Use SPSS19.0 test statistical software to do statistical analysis, and put P < 0.05 as difference. And then, there is statistical significance.
     RESULT
    1.For all the wearer, after wearing for 1 week ~ 1 month, the naked eye vision basically recovered to 1.0; The eye axis changes before and after wearing, and the increase of eye axis is statistically significant. But 1 week and 1month after wearing, if eye axis became slightly shorter, the difference will be with statistically significant. Shown in table 1.

    DISCUSSION
      Orthokeratology in this paper is Ortho-k Leans designed by new digital model technology and we also call it Rigid Gas Permeable Contact Lens for Orthokeratology. It is a kind of reverse geometric designed rigid corneal contact lens, and it not only has the unique effect of myopic correction, but also can control the development progress of myopia. The researches of Chop, Chewng, S W and some other experts shown that: (1), For the group who accept the treatment of Ortho-k lens, the average growth of axial is 0.29 + / - 0.27 mm after 2 years, while for the control group (normal frame glasses), after 2 years, the axial average growth is 0.54 + / - 0.27 mm. Obviously, the former one is only 1/2 of the next one. Xie Peiying [2] and Kakita [3] got the similar results, and the result is similar with the average growth 0.36 + / - 0.27 of eye axis after wearing Rigid Gas Permeable Contact Lens for Orthokeratology for two years in this paper. Although Ortho-K Lens can′t fully control myopia increase, but it played a positive role in myopia control; after wearing lens for a week and a month, the eye axis slightly became shorter. There need more observation and cases to get the answer of the question that if this is connected with the flattening of central cornea after wear Ortho-k Lens or not.
    In clinical work, we can frequently find that the control effect is different for different wearer. If there any objective factors, such as the design? In this paper, we used the latest Rigid Gas Permeable Contact Lens for Orthokeratology design, and try our best to reach the wearing effect.
    And According to the relationship of age and diopter, age will not influence diopter, but, but for the depth of the myopic degree, it have an effect on the control. For example, for moderate myopia group, if the slow axial grow is related to peripheral refractive imaging. Rempt’s [4] studies have shown that for patients who were with peripheral refractive myopia, they were not easy to get myopia, but for the patients who were with the surrounding refractive hyperopia, it is easy to get myopia. Chen Zhi [5] and some other expert confirmed that the Ortho-k lens can reshape the former cornea surface, make the central corneal flattened, peripheral corneal steeped, and then, myopia drift happened in the surrounding diopter. As known to all, modern Ortho-k lens design is four arc design, and the design of arc zone and inverse arc zone of the arc design is related with the decrease of degree, and the higher the degree must be relative to the flat base arc and the steep inverse arc design, in order to provide the good visual quality (6);
    Admittedly, the higher degree needs the more steep reversal arc to let the surrounding refractive imaging drift to myopia. We will discus the reason which makes the eye axis increase: whether it is influence by the difference wearing effect between medium and low myopia, or the difference of low myopic eye axis itself.

    ABSTRACT

    Objective:To explore the effect of digital design corneal reshape lens-- Myopia Corneal Therapy (MCT) on myopia correcting and to investigate its superiority as compared with traditional Ortho-k lens. 
    Methods: 118 eyes of 60 patients from Eye Disease Center of Shanghai in 2004 were arranged to take Rigid Gas Permeable Contact Lens for Orthokeratology or traditional ortho-k lenses(TOL) randomly, their ages ranged from 7 to 19 years old, the data obtained was analyzed by SPSS11.0 software. After wearing 3-mon of MCT or tranditional ortho-k lens , compared with tranditional ortho-k lens, the superiority of MCT on preventing and improving myopia of adolescent was evaluated by analyzing the naked eyesight, topography, centralized positioning, movement and tightness of lens. 
    Results: 3-mon after wearing MCT, the patients’ eyesight(unadded vision) improved significantly, the mean value was 0.81±0.28D, while the mean eyesight of traditional ortho-k lens was 0.58±0.30D, the difference between mean values was significant (t=4.31,P=0.001<0.05) although the difference between mean squares was not significant (F=1.79); More eyes with MCT returned to a round shaped topography ( in MCT is 86.7%, in traditional ortho-k lens is 36.7% ); centralized positioning of lens in 80 percent eyes were good in  MCT, which was higher than that in traditional OKT( 33.3%). All eyes wore MCT had a fine lens movement and it was higher than 73.3% of tranditional ortho-k lens. The tightness of lens in MCT eyes was also better than that in tranditional ortho-k lens (96.6% in MCT vs. 70% in TOL).
    Conclusion: For preventing and correcting myopia in adolescent, to wear MCT was superior to wear traditional ortho-k lens. No adverse effect had been found in two groups.

    INTRODUCTION

      The Myopia Corneal Therapy (MCT) lens was developed and designed by the Web Optometry Research Institute, it is a new way to prevent and correcte myopia. Compared with traditional ortho-k lens therapy (TOL), MCT is much creative and has good curative effect. We could learn more about its superiority from the comparison of clinical application between MCT and traditional TOL. 
    1. General data and methods

        1.1 Subjects
      60 patients from Eye Disease Center of Shanghai in 2004 were divided into 2 groups and each group had 30 patients, the patients in groupⅠwere treated with Rigid Gas Permeable Contact Lens for Orthokeratology while those in groupⅡwere treated with traditional ortho-k lens. The 30 MCT patients’ age ranged from 8 years old to 19 years old (mean 14.6±2.5). 21 of 30 in MCT group were female and the remaining 9 were male, 29 left eyes and 29 right eyes. Refraction scope ranged from -1.75 to 10.25D, average was -5.26 ±1.93D, astigmatism scope ranged from -0.50 to -2.50D, 2 patients were single eye wore (6.7%); The 30 TOL patients’ age ranged from 7 years old to 18 years old (mean 13.1±3.5). 21 of 30 in TOL group were female and the remaining 9 were male, 30 left eyes and 30 right eyes. Refraction scope ranged from -2.25 to 9.50D, average was -5.30 ±1.93D, astigmatism scope ranged from -0.50 to -2.75D. 
        1.2 Methods
      Other eye disease and contraindication were excluded by preocular and fundus examination. After examination of myopia diopter, corneal topography, intraocular tension, the eyelids and tear film, the best parameters of lens were determined and lens were prepared. Then the patients were taught how to wear and care lens. Make a schedule to take on and take of as well as follow up check. Ten times follow up check should be arranged in one month. The item of re-check included cornea, naked eyesight, corneal topography, centralized positioning of lens, tightness and movement degree of lens and so on. To prevent and correcte myopia either by Rigid Gas Permeable Contact Lens for Orthokeratologyor by traditional ortho-k lens belongs to corneal molding, which means it was not by operation but only by taking corneal lens to change the curvature radius in the central of the cornea, then to reduce the power of the myopia and improve the naked eyesight temporarily. After returning to the best eyesight, the lens should be taken every night to consolidate its effect(1) . So the increasing of naked eyesight after taking lens was a key item for evaluation. Which lens was more effective on improving naked eyesight had been compared in this research by us. The decenter of lens would influence the visual function of patient after treatment, so it was also necessary to evaluate the centralized positioning of lens(3).
    Statistics analysis: SPSS 11.0 software was used for data statistics analysis in this research. F homogeneity test on mean squares of 2 groups was carried out firstly, then T test was carried out to verify if the new Rigid Gas Permeable Contact Lens for Orthokeratology had an obviously improvement compared with the traditional ortho-k lens, a=0.05.
    2.Result
      Evaluated from the follow up check at 3 months after wearing lens, the naked eyesight of MCT patients had much obvious improvement than that of the TOL patients, and the difference between mean values was significant (t=4.31,P=0.001<0.05) although the difference between mean squares was not significant (F=1.79). The average naked eyesight of MCT patients was obvious higher than that of TOL patients (0.81±0.28 vs. 0.58±0.30); More MCT patients had shown a circle change on corneal topography and that is better than those taking TOL lens, the number of patients with a circle corneal topography was twice as that of TOL patients (shown in Table 1). Centralized positioning of lens in MCT patients was much better than those in TOL patients, the stability of lens in the center of cornea was tightly related to the correction of eyesight and degree of comfort(3), the centralized positioning of lens also had direct influence on the shape-change of cornea and changes of diopter. According to the data in the off-center probability figure, we knew that the positioning of lens in MCT group was much better than that in the traditional ortho-k lens group. Some research indicated that off-center of lens had something to do with the patient selecting and lens design in cornea molding lens therapy, the off-center of lens affected the visual function of patient(3). All patients who wore Rigid Gas Permeable Contact Lens for Orthokeratology had a good movement and were better than those wore traditional ortho-k lens. The degree of tightness of MCT patient was also better than that of TOL patient.


    3. Discussion

      Digitalization corneal reshape lens was a new generation full alignment corneal re-shape lens, and it also was one of cornea molding therapy. It was a new technology developed with corneal topography and was digital designed according to all data of cornea. Because it had a higher rate of success than traditional ortho-k lens, the patients felt much satisfied with it. The simplification of procedure for examination and lens preparation also reduced the doctors’ harassment on lens’ adjusts, because the prescription was no longer determined by trial fitting. The rigid contact lens had been proved to have some effect on preventing myopia progression according to the last research in the Ohio State University, USA(5); but in some condition and to some extend, the Myopia Corneal Therapy had a better effect on correcting and preventing myopia progression according to the research of THOMAS REIM(6). We think the MCT have a better effect on correcting and preventing myopia progression, but it needs high professional skills on ophthalmology and optometry during the examine and lens fitting as well as fellow-up.  The effective and safety service will be available to astigmatism myopic patients if the regulations of SFDA are strictly followed during the whole procedure(4).

    MCT Technology Makes Pathologic Myopia not Horrible Any Longer
     

      Myopia is a symptom of the vision problem. In some people´s eyes, myopia is important but for some other´s, it is not so important. Many people think that the myopia caused by bad habit is a little case and a pair of glasses can solve it. The parents will be worry and try them best to find some treatments, only when the child gets congenital amblyopia. Besides, there is a kind of myopia which will happen in the early time and is connected with gene. It is called pathologic myopia or progressive myopia. If you are with myopia and a pair of glasses, but the degree of myopia is increasing year by year, be careful! You maybe get pathologic myopia.

      Now, in China, there are a lot people with myopia. But the most of them are simple myopia. Simple myopia and pathologic myopia are all in the range of myopia, but the principle and result are quite different. Simple myopia is caused by bad habit of using eyes, commonly happens in teenager. Wearing glasses can control its development and also the surgery. For pathologic myopia, it happens before 12 years old and wearing glasses or doing surgery could not stop the degree development completely. This the most different part between simple myopia and pathologic myopia. 

      How does pathologic myopia happen and what symptoms it has? Will it bring complications or not? Is there any treatment can control it development?

      Pathologic myopia is also called degenerative myopia. It is a kind of progressive myopia and the morbidity is 1%-2% in China. The development of this myopia is very fast and the degree will increase after 25 years old. The clinical symptom of it is the constantly growing of the axis oculi. The degree will increase with the age and damage the retina and choroid. 

      There will be a terrible decline of naked vision for a pathologic myopia patient and commonly the vision will be lower than 0.1. Even with glasses and contact lenses, their vision ability will not be a normal lever. The eyeball will be bigger and longer and the patient will with eye pain, headache, nausea, insomnia when seeing something.

      High myopia will with pathologic changes of the eye and the high myopia is a kind of autosomal recessive disorder. This means only a pair of disease gene will cause high myopia and if a disease gene and a healthy gene will not cause it. If a child´s parents are both high myopia patients, the rate of this child being high myopia is 90%.      

      Pathologic myopia´s degree is high, and the vision is not clear. It will cause complications, because pathologic myopia patients usually have high intraocular pressure. Its complications includes eye disease (Retinal degeneration inflammation, sublatio retinae and macular hemorrhage are all common and serious complications), posterior staphyloma (the thinning and swell of posterior scleram), cataract (clouded lens), and glaucoma (high intraocular pressure), amblyopia and strabismus  (With high myopia when young is easy to be suffered amblyopia).

      If these complications happen, it will do great damage to the eyes, and even will cause blindness. The higher degree pathologic myopia has, the greater the risk is. Generally, medical treatment cannot completely correct the refractive error caused by pathologic myopia, and cannot avoid rebounding. So treatment of pathologic myopia is very difficult. 
      The treatments of pathologic myopia commonly are surgery and wearing contact lenses (OrthoK Lens). After surgery, pathologic myopia patients can get good vision, but also cover their conditions. The surgery is expensive but has a risk. A few years the degree would recover and continue to grow. So doing surgery is not the best way; the traditional Orthok lenses can´t bring a good vision to pathologic myopia patient, only can control the development in a certain degree.  Because the traditional Orthok Lens has the risk of trial fitting, and the probability of damage to the cornea is on the high, many people do not want to use it.
      Surgery and traditional Orthok lens can only slow the degree development of pathologic myopia. Is there no other method can combine the advantages of both? No damage, low cost but with good eyesight? 
      This is a technical blank and many Ophthalmology and Optometry institutions studied in this field, but no one can successful past the clinical test, except MCT technology.
      Why MCT technology can break the difficulty?It is because MCT technology is the combination of Ophthalmology and Optometry. After 14 years study and research, MCT technology is the research result which costs 14 years` study from Web Optometry Institution and Shanghai Furen Ophthalmology Institution and some other national optometry and ophthalmology research institutions 
      MCT technology is the best technology in the field of Ophthalmology and Optometry, because MCT technology depends on precise objective digital examination, like-holographic scanning of cornea which collect thousands of data for customization. The lenses are perfectly agreed to the cornea. It greatly improves the treatment range of myopia and reduces the probability of keratitis.
      The production of the lens is also important. MCT technology is born in China, but the lens is produced in the US. Now there is a more excellent production skill in the United States and the factory in the US can ensure the quality. There is over 60 years experience in the field of OrthoK lenses production in the US. The factories there can reach complex requirements of Rigid Gas Permeable Contact Lens for Orthokeratology design. 
      MCT technology can correct high myopia, astigmatism presbyopia, and sequela of laser surgery, child and adult amblyopia, dry eyes and so on. The principle of the lens is to stop the increasing of the axis oculi by the focus from eyelid and avoid corneal forward protruding, reasonable change the shape of the corneal surface, make the cornea more flat, reduce myopic degree.
      Comparing with traditional Orthok Lens, Rigid Gas Permeable Contact Lens for Orthokeratologyes have a better ability of the myopia control and a larger using range. It can be worn in the daytime or at night. After wearing at night, it can keep a good naked vision in the daytime. In dealing with the problem of pathologic myopia, MCT technology can effectively slow down the development of the myopic degree. If the degree of a pathologic myopia patient increases 200 degrees in two years, wearing the Rigid Gas Permeable Contact Lens for Orthokeratology can reduce this increase into 25 degrees every year. This can greatly reduce risk of blindness of the pathologic myopia patient. The nursing of Rigid Gas Permeable Contact Lens for Orthokeratology is very simple. We have a patented Lens Cleaning Case and water eye spray to help you to make sure the clean of the lens. 
      MCT technology not only can bring pathologic myopia patient good vision, and also can slow the development of degree. It will not bring keratitis, and is easy to wear, easy to take off, easy to nurse. Believe MCT technology, it will bring you good health vision.
     
    Cherish Bright; Keep Pathological Myopic Complications Away
      
      The vision problems break out in recent decade with the development of Electronic Technology and the changes of life and work environment! More and more people realize the threat from vision problems—influence the daily life or even lost the bright.   
      Generally Speaking,the vision problem mainly focuses on myopia and the most common myopia is simple myopia which is with a high risk but easy to be treated and less complications. Comparing with simple myopia, although the incident rate of pathological myopia is much lower, it is hard to be treated and with many complications. Simple myopia and pathological myopia are both in the range of myopia, but there are big differences between their pathogenesis and damages. The blinding rate of pathological myopia is much higher than simple myopia. The treatment of pathological myopia is one of the most important subjects in the field of optometry and ophthalmology.     
      Pathological myopia is also called degenerative myopia and the symptoms of it are the degenerative deepening of diopter, the increasing of eye axis, and the degenerative damages to eye contents and retinal detachment organization. It will cause the vision disorder and the incidence rate of it is 1% to 2%. The degenerative myopia happens in the early age, but will develop after growing up and the myopia will reach over 1500 degrees. 
      According to incomplete statistics, there are over 10 to 20 million people in China suffering by pathological myopia. Some patients lose their labor capacity when 40- 50 years old. In fact, pathological myopia, just liking the disease in other parts of our body, is not with fatal damage like blindness itself, but the complication will.  
      There is a close relationship between high myopia and pathological myopia. High myopia can be divided into to groups which are according if there any change of eye: one is simple high myopia which is with high degree and will stop the development till a certain step; the other one is pathological myopia which is the major one—if with high myopia, please not ignore it, the check to the fundus is very important.
      We are all familiar with cataract and glaucoma. Comparing with simple myopia which can be solved by a pair of glasses, they are the bright killers of our eyes. The blindness which is caused by pathological myopia and glaucoma is irreversible. And, the question is does cataract and glaucoma happens occasionally? No, of cause, they are all the complications of pathological myopia.      
    In general, the symptom of cataract is the turbidity of lens, and the symptom of glaucoma is the high intraocular pressure which will cause optic atrophy. They are the objects which people want to conquer in the field of ophthalmology, but now, it is still hard to find an absolutely effective way, and the best way is to prevent.
    Retinal Degeneration, Retinal Hole, Retinal Detachment, Macular Degeneration, Macular Hemorrhage are all the common serious complications of pathological myopia. They are the main reasons for the blind eyes, and belong to the fundus lesions. Medical clinical and practice have proved that Macular Degeneration, Bleeding, Retinal Detachment must be treated as high blind diseases.
      In addition, the pathological myopic complications also include posterior scleral staphyloma, strabismus and amblyopia. The changes posterior scleral staphyloma brought to our eyes are the thinning and swelling of posterior scleral which will affect the eye health. Strabismus and amblyopia will make the person get myopia when he or she is young.
      These complications are the ultimate reason why people are afraid of the pathologic myopia. Pathological myopia happens most from genetic, and fatigue won´t cause it. So pathological myopia is not easily to occur, but its happening can let your eyes in the danger of blindness.
      If the myopic degree can determine the degree of pathological myopia, the higher degree means the higher complications rate, and also the higher risk to get blind. Generally speaking, the pathological myopia is growing, and each extended 1 mm of eyeball axial is equal to the increasing of 300 degrees of myopia. Normal human eye axis in between 22.5 ~ 23.5 mm , and eye axis of pathological myopia patients can be 30 mm, therefore their myopic degree is very high, and also intraocular pressure.
      All above shows the threat of blindness pathological myopia brings to our eyes. To find breakthrough to slow down the development speed of pathological myopia as soon as possible is the real key.
      "For pathological myopia, the higher degree, the higher the risk, and there is no method can control its development. If we can slow down its growth rate, at the same time, reduce intraocular pressure, the risk of blindness can be greatly reduced." This is a constructive opinion for ophthalmology specialist in dealing with pathological myopia. To put the idea into practice is not easy, but there are always more solutions than difficulties — MCT technology appears, and breaks the difficult situation!
      First of all, MCT technology effectively reduces the intraocular pressure of pathological myopia patients. It can indirectly increase anterior chamber angle by raising surrounding cornea. This can also promote aqueous humor reflux, reduce intraocular pressure, and guarantee aqueous humor circulation unobstructed. Once, intraocular pressure reduced oppression to optic nerve, the occurring probability of complications such as glaucoma also could follow to reduce.
      Secondly, MCT technology effectively slows down the growth of pathological myopic degree. With MCT technology lens and the power of top eyelid, the increasing of eye axis is stopped by reactive force. It can also prevent corneal protruding, and at the same time, reasonable change the shape of the corneal surface, and reduce refractive power of eye, and finally reduce myopic degree. If a pathological myopia patient´ myopic degree grew 200 degrees in two years, after wearing the Rigid Gas Permeable Contact Lens for Orthokeratology, in every year, the degree will only increase 25 degrees. The growth rate of Pathological myopia degree reduced, and then the blindness risk caused by rapid degree increase is also greatly reduced.
      "Reasonable reducing intraocular pressure, effective slowing down the speed of myopia development, in these two aspects, MCT technology made a breakthrough, and alleviated the invisible crisis of pathological myopia." ophthalmology & optical experts expound the efforts how MCT technology deals with pathological myopia.
      Indeed, since MCT technology successful developed by Web Optometry Institute and Shanghai Furen Ophthalmology Institution and other national ophthalmology and optometry institutions, it have been more than 10 years, and now there are thousands patients who are with bad vision accepted the correctional treatment from MCT. MCT technology contributes its own strength in the prevention and treatment of blindness
    Pathological myopia and its complications are high blinding diseases. Exam fundus timely, find and effectively control the complication. This is the only way to keep the bright in our eye!


          If the vision decreases after laser surgery,must consider the possibility of pathological myopia
          
      The expansion of myopic population is great in the end of the 19th century and the beginning of new century. At this stage, the frame glasses market rapidly expanded, the optical shop in street started popping up into people´s field of vision, and this is because of the concentrated growth of myopic population.
    The craze of glasses is from the expanding of myopic population, and of course, also the domestic economic situation. On one hand, because the cost of myopic treatment technology is very high, it can not be popularized; on the other hand, because the development of correction technology is not as fast as the expansion of myopic population, few people will think about the correction of myopia. Because frame Glasses is cheap, simple and can help patients restore vision, it wins the favor of myopia patients.
    But changeable in prosperity and decline capricious in rise and fall, now, although the crowd of myopia is still expanding, but the craze of frame glasses is already cooling, economic development makes people rich, and they hope there is a kind of technology which can correct myopia. What people want to do is not only the restoration of good vision, but also the farewell to bad vision. Then, laser Surgery and corneal reshaping technology which could keep up with the times appeared.
    The growth of laser surgery is not an accident. It can satisfy myopes who are not willing to wear frame glasses but also with good vision. And for some problems which frame glasses cannot solve, it can also play a role in a certain extent. Laser surgery has developed from RPK, LASIK, and LASEK to today´s femtosecond laser. Now people can accept its expenses, and its safety is also rising. Laser surgery not only eases enlargement problem of myopia, but also bring bad vision patients a new choice.
    Technology is in progress, and also does the disease. They became more and more complex. Take myopia as example, the occurrence of high myopia was very less before, but now it is relatively common. Laser surgery can correct a certain degree of high myopia and help part of patient restore vision, but it can´t actually control pathological myopia. This is the limitation of laser surgery.
    Generally, pathological myopia is also called progressive high myopia. The different between it and simple myopia is: the development of simple high myopia will cease when reach a certain degree, while pathological myopia will unlimited develop until patient lose their vision or get blind. In normal circumstance, pathological myopia often will be treated as simple high myopia, and also will be regarded as low myopia in the initial period of development. People with moderate or high myopia are the main crowd of laser surgery, and then there will be a problem. Some people will be with relatively stable visual acuity which meets the expected effect after laser surgery, but for some patients, after laser surgery, over a period of time, their vision will back to the former level, and myopia degree continues to grow. So why?
    We began with the principle of laser surgery. It is a kind of cold laser which can cut the corneal surface, make its radian decrease, then reduce the refractive power and finally bring good vision. But there are two reasons of the formation of myopia. Refractive error is just one aspect, and there is another aspect: the excessive extension of the eye axis. This is also the main reason for the formation of myopia. So from myopia pathogenesis, laser surgery can not fundamentally control the development of myopia.
    "If a patient did laser surgery which was successful, and their eyesight also return to normal level without redraw for a long time, that patient mostly is with simple myopia (including simple high myopia); but if a patient did laser surgery which was very successful, but after half a year, the bad vision was back, and continued to develop, then we should consider if what they get is pathological myopia." this is the understanding of the original designer of MCT technology, Professor Wang. Now he has been engaged in the prevention of blindness for over twenty years, and his original MCT technology bring many myopes the Gospel.
    Professor Wang also said, the vision decreasing after surgery is also related with the operation itself. Insufficient preoperative optometry, incorrect calculation, and not-timely review, all of them may be the cause of the vision back. If the operation was no problem, but the vision decreased, then we could determine if what patient got is pathological myopia. And these patients are better to do fundus photography to observe the changes every year, and also get diagnosis as early as possible, and then take measures to control.
    Why will the vision of patients who are with pathological myopia decrease after laser surgery? The reason is the pathogenesis of myopia: the excessive growth of eye axis. For simple myopia patients, the development will cease after reaching a certain degree, the possibility of continuous growth of the eye axis is very small, and the increase will be very slight, so if we solved refractive error, we can basically solve bad eyesight. But pathological myopia is different. The reason why it can unlimited develop is mainly because the eye axis will keep growth, and this increase is far outweigh the simple myopia after laser surgery. So for pathological myopia, the laser surgery can just solve the problem of ametropia, and restore vision temporarily, but eyesight will still return to preoperative levels, and degrees will continue to deepen.
    Pathological myopia will unlimitedly develop, and the key is to control this development. In present, there is no medical technology can completely prevent pathological myopia development, and the best way is to control the speed of development. If the development is slow down, the bright of patient will be kept for a longer time. And in the filed of the slowing of pathological myopia development, MCT technology is in the leading place in the world.
    What is its representation? Firstly, MCT technology controls the development of degree in the aspect of myopia pathogenesis. Through the directly power from palpebra superior, it stops the increase of eye axis, revises the radian of cornea, avoids the forward protruding of cornea, makes it more flat and finally reduces the degree of myopia.
    It is the best method for pathological myopia patients, because it can help them restore vision, and control the development of degree in a certain extend. And how effective it is? For example, if the degree of a pathological myopia patient increases 200 degrees a year, and after wearing Rigid Gas Permeable Contact Lens for Orthokeratology, it will only develop 25 degrees a year. In this way, its development speed will slow down considerably, and the chance of serious eye complications is also greatly reduced and then directly extended the more bright time.
    So, if eye problems of patients who did laser surgery are back, be careful. We should consider the possibility of the pathological myopia, and take effective measures to diagnose and control it. Only this can help them keep their bright and ensure the safety of the eyes. Of course, the leading MCT technology can be your trustworthy choice!

              MCT Technology Makes Pathologic Myopia not Horrible Any Longer
      
      Myopia is a symptom of the vision problem. In some people´s eyes, myopia is important but for some other´s, it is not so important. Many people think that the myopia caused by bad habit is a little case and a pair of glasses can solve it. The parents will be worry and try them best to find some treatments, only when the child gets congenital amblyopia. Besides, there is a kind of myopia which will happen in the early time and is connected with gene. It is called pathologic myopia or progressive myopia. If you are with myopia and a pair of glasses, but the degree of myopia is increasing year by year, be careful! You maybe get pathologic myopia.
      Now, in China, there are a lot people with myopia. But the most of them are simple myopia. Simple myopia and pathologic myopia are all in the range of myopia, but the principle and result are quite different. Simple myopia is caused by bad habit of using eyes, commonly happens in teenager. Wearing glasses can control its development and also the surgery. For pathologic myopia, it happens before 12 years old and wearing glasses or doing surgery could not stop the degree development completely. This the most different part between simple myopia and pathologic myopia.
      How does pathologic myopia happen and what symptoms it has? Will it bring complications or not? Is there any treatment can control it development?
      Pathologic myopia is also called degenerative myopia. It is a kind of progressive myopia and the morbidity is 1%-2% in China. The development of this myopia is very fast and the degree will increase after 25 years old. The clinical symptom of it is the constantly growing of the axis oculi. The degree will increase with the age and damage the retina and choroid.
      There will be a terrible decline of naked vision for a pathologic myopia patient and commonly the vision will be lower than 0.1. Even with glasses and contact lenses, their vision ability will not be a normal lever. The eyeball will be bigger and longer and the patient will with eye pain, headache, nausea, insomnia when seeing something.
      High myopia will with pathologic changes of the eye and the high myopia is a kind of autosomal recessive disorder. This means only a pair of disease gene will cause high myopia and if a disease gene and a healthy gene will not cause it. If a child´s parents are both high myopia patients, the rate of this child being high myopia is 90%.     
    Pathologic myopia´s degree is high, and the vision is not clear. It will cause complications, because pathologic myopia patients usually have high intraocular pressure. Its complications includes eye disease (Retinal degeneration inflammation, sublatio retinae and macular hemorrhage are all common and serious complications), posterior staphyloma (the thinning and swell of posterior scleram), cataract (clouded lens), and glaucoma (high intraocular pressure), amblyopia and strabismus (With high myopia when young is easy to be suffered amblyopia)
    If these complications happen, it will do great damage to the eyes, and even will cause blindness. The higher degree pathologic myopia has, the greater the risk is. Generally, medical treatment cannot completely correct the refractive error caused by pathologic myopia, and cannot avoid rebounding. So treatment of pathologic myopia is very difficult.
    The treatments of pathologic myopia commonly are surgery and wearing contact lenses (OrthoK Lens). After surgery, pathologic myopia patients can get good vision, but also cover their conditions. The surgery is expensive but has a risk. A few years the degree would recover and continue to grow. So doing surgery is not the best way; the traditional Orthok lenses can´t bring a good vision to pathologic myopia patient, only can control the development in a certain degree.  Because the traditional Orthok Lens has the risk of trial fitting, and the probability of damage to the cornea is on the high, many people do not want to use it.
    Surgery and traditional Orthok lens can only slow the degree development of pathologic myopia. Is there no other method can combine the advantages of both? No damage, low cost but with good eyesight?
    This is a technical blank and many Ophthalmology and Optometry institutions studied in this field, but no one can successful past the clinical test, except MCT technology.
    Why MCT technology can break the difficulty?It is because MCT technology is the combination of Ophthalmology and Optometry. After 14 years study and research, MCT technology is the research result which costs 14 years` study from Web Optometry Institution and Shanghai Furen Ophthalmology Institution and some other national optometry and ophthalmology research institutions.
      MCT technology is the best technology in the field of Ophthalmology and Optometry, because MCT technology depends on precise objective digital examination, like-holographic scanning of cornea which collect thousands of data for customization. The lenses are perfectly agreed to the cornea. It greatly improves the treatment range of myopia and reduces the probability of keratitis.
    The production of the lens is also important. MCT technology is born in China, but the lens is produced in the US. Now there is a more excellent production skill in the United States and the factory in the US can ensure the quality. There is over 60 years experience in the field of OrthoK lenses production in the US. The factories there can reach complex requirements of Rigid Gas Permeable Contact Lens for Orthokeratology design.
    MCT technology can correct high myopia, astigmatism presbyopia, and sequela of laser surgery, child and adult amblyopia, dry eyes and so on. The principle of the lens is to stop the increasing of the axis oculi by the focus from eyelid and avoid corneal forward protruding, reasonable change the shape of the corneal surface, make the cornea more flat, reduce myopic degree.
    Comparing with traditional Orthok Lens, Rigid Gas Permeable Contact Lens for Orthokeratologyes have a better ability of the myopia control and a larger using range. It can be worn in the daytime or at night. After wearing at night, it can keep a good naked vision in the daytime. In dealing with the problem of pathologic myopia, MCT technology can effectively slow down the development of the myopic degree. If the degree of a pathologic myopia patient increases 200 degrees in two years, wearing the Rigid Gas Permeable Contact Lens for Orthokeratology can reduce this increase into 25 degrees every year. This can greatly reduce risk of blindness of the pathologic myopia patient. The nursing of Rigid Gas Permeable Contact Lens for Orthokeratology is very simple. We have a patented Lens Cleaning Case and water eye spray to help you to make sure the clean of the lens.
    MCT technology not only can bring pathologic myopia patient good vision, and also can slow the development of degree. It will not bring keratitis, and is easy to wear, easy to take off, easy to nurse. Believe MCT technology, it will bring you good health vision

           Save the potential from the blinds! MCT technology´s strong control for pathological myopia
      
      China´s myopia rate is 31%, which is the highest one of the myopia countries, and with a growing trend. Myopia becomes entrance obstacle for a lot of people, myopia is an increasingly large crowd, myopic patient´s condition become more and more complicated, that have gradually increased to be a concerned social phenomenon.
    According to the clinical pathology, myopia can be divided into simple myopia and pathological myopia.
    Simple myopia means the general myopia, usually diopter is less than 600 degrees, myopia develops slowly, and vision can be mostly corrected well. Normal eyeball organization is no pathological change, and the genetic factors are not obvious. Generally, the youth developed and became mature, myopic degree will be no longer increases.
    Pathological myopia can be also named as progressive myopia; the diopter is more than 600 degrees, as high as 4000 degrees. Generally, once appearing (between5 to 10 years old people), number of degrees can grow along with the age and continue development after 25 years old, and eyesight is not easy to correct. Many of the eye organization can have a series of pathological changes, such as eye disease, posterior staphyloma, cataracts, glaucoma, amblyopia, and strabismus. With the serious influence to the patient´s quality of life, it is one of the common eye diseases in our country, and the prevalence is about 1% to 2%.
    Pathological myopia is mainly affected by the occurrence of genetic, environmental, biomechanics these three factors. The retina will break away from the eye once appearing hiatus, and its result commonly is blindness. How to save the large potential blindness people in the future? How to improve public of consciousness and to help pathological myopia patients got the correct treatment and rehabilitation method. How can reduce the incidence of this disease and blind rate?
    At present, the treatments of pathological myopia are wear glasses, corneal surgery, sclera surgery, lens surgery, and some other concrete operation method. For the teenagers, their eyes are not suitable for doing surgery and the MCT technology offers new hope for pathological myopic teenagers. MCT technology continuously breaks through the limitation of traditional corneal model, and has 23 original innovation breakthroughs.
    Pathological myopia´s biggest problem is the constant development of degree constantly, and also appearance of complications. The treatment for the myopia and ocular hypertension becomes more difficult.
    Pathological myopic treatment principle of MCT technology, first, to restrain the axial growth by the direct effect of the upper eyelid; Second, to restrain the cornea convex forward directly, and make the cornea more flat; Third, the vision is good when removing and wearing the lenses, make the ciliaris relaxed, crystals become flat, release the spasm; Fourth, the vision is improved all day, eye muscle and ciliaris muscle are all relaxed, the IOP, which is the motive power of the myopia, is reduced relatively. The most important design of MCT is to drive up around the cornea, so that the width of anterior chamber angle increases, the aqueous outflow increases relatively, and the eyes IOP reduced. A statistical data supports that the control effect of myopic MCT technology is better than the traditional technology and even more significant. Every year, myopic degree will develop only minus 0.047 DS (4.7 degrees), including simple myopia and pathological myopia.
    In order to prevent from the pathological myopia, the sufferers prevent pathological myopia by genetic counseling. Take measures of eugenic and superior action, and close relatives or both high myopia persons should avoid to marry. the Pathological myopia children see thing in near way should have been inspected in time when they are under 3 years old. Once children were diagnosed as pathological myopia, he or she should use MCT technology to control as early as possible; the children with amblyopia should make the amblyopia training.
    Except the general method of preventing myopia, the sufferers should pay special attention on using eyes reasonably, to avoid using eyes excessively with the bad visual stimulation; prevent myopia deeper, and maintain or improve the vision. Pathological myopia must wear Rigid Gas Permeable Contact Lens for Orthokeratology continuously to reduce or suspend myopic development, to inspect the eyes, and to treat other eye diseases and systemic disease timely.
    Pathological myopia is a lifelong eye disease. Once the serious complications appear, there is the irreparable damage for the visual function, so the inspection, control and prevention of pathological myopia and complications are so important. Checking regularly, finding early, and managing complications, these are the keys to avoid the blindness caused by pathological myopia. The general patients should review one time every half a year, but if there is vision loss, or eye pain occurs, the patients should immediately seek doctors.

                The importance of pathological myopia prevention in adolescence
      
      "The country will be strong, if the youth are strong," this is what Mr. Liang Qichao told us in "Said Young China ". For a long time, the youth group always attracts attentions from the society, because they are the reserve force of future development.
    Time is changing, and the way of the teenager growth is change too. When talk about teenager, many people will associate them with "rebellious, sunshine, studying, test, training, Internet bar and games", these nouns have close relationship with teenagers, and also reflect the growth of them. But no matter how their growth modes change, the mental health of teenagers is still the focus.
    According to social investigation, it shows that at present, for the city youths, the most common health problem is fat, while the malnutrition is the common health for the rural youths. The happening of this kind of circumstance is caused by the unbalanced economic development, and at this moment it is difficult to be effectively solved. But whether urban teenagers or rural adolescents have a common health problem and this is bad eyesight.
    Poor eyesight is the most concentrated problem among adolescent. And in China, myopia incidence rate among the youths has risen to 60% which is more than in Japan and the United States. This is a dangerous signal, because the expansion of myopia crowd will not only influence the special industry development, but also bring harms to the youths. The damage of simple myopia of teenagers is the vision loss, and the damage of pathological myopia of adolescents is the visual disturbance, eyes histogenesis lesions, and even blindness after grown-up.
    Pathological myopia also can be called progressive myopia. And the features of this eye disease are the progressive deepening of diopter, the growing of eye axis, and the progressive damage of eyes and retinal detachment organization which will cause visual function disorder.
    The simple myopia damage among adolescents is relatively small, but it is with a very high occurrence rate; the pathological myopia occurrence rate is very small (20% to 30%), but the damage is very dangerous. For the pathological myopia of teenagers, if not to prevent and control the risk of blindness, the blindness will be closer. At the same time, a lot of ophthalmology said that the blindness prevention and treatment of teenagers is the major breakthrough of adolescent pathological myopia. For adolescent pathological myopia, the effective prevention and control is the best way.
    So how to do the adolescent pathological myopia prevention and control? There are the answers from the experts.
    "Although the harm of pathological myopia is serious, there are ways to minimize it. And it needs the efforts of parents, doctors and the children. Only parents really take care about children’s vision problems, doctors try their best to find a way and children protect their eyes, pathological myopia incidence rate will decrease, and the disease also will get effective control." Professor Wang in Shanghai Furen Ophthalmology answered. He has been a senior professor in the fields of ophthalmology and optometry and his original design digital MCT   technology brought the Gospel to thousands of patients with poor vision, which includes some pathological myopia patients.
    Dealing with teenagers´ pathological myopia, first of all, their parents cannot treat it carelessly. If parents themselves are simple myopia patients, the children will be with myopia genes and with a high probability of myopia. If parents themselves are with pathological myopia, the myopia probability of these children is higher. We should pay much attention to this kind of situation. Once discover the child appears vision problems, the illness should be timely diagnosed.
    Moreover, pathological myopia generally occurs early. If a child get myopia before 6 years old, and with the body development, eyeball and eye axis growing, we must pay attention to this situation and consult oculists, check the degree development, and diagnose the illness.
    And after child getting myopia, the vision degree develops very quickly which get over 600 degree when 11 to 12 years old. Then we also should pay attention that the fast degree development is one of the characteristics of pathological myopia. Children need the further inspection of their vision, and if the result is pathological myopia, we shall take timely measures to control it.
    For many parents, they don´t know how to diagnose the pathological myopia. Then Professor Wang also provided a solution.
    He said: "at present, the best method to diagnose pathological myopia is fundus photography. Once the child meets one of the above cases, you should take children to do fundus photography, and check the health of children retina and optic nerve system. If make sure that it is pathological myopia, we have to control it as soon as possible. At the same time, we still need to do fundus photography yearly to observe the change of eyes"
    In addition, the adolescent pathological myopia is also very important for doctors. If the doctors found that the teenager’s myopic degree development too fast, or the degree is too high in the work, they should guide the parents take measures to inspect and control it. Especially the opticians, if they found that there is with the possibility that what the adolescent get is pathological myopia, they should not only let the children get a pair of frame glasses, but also guide the parents and children to hospitals for further inspection. The early diagnosis can give more time to take effective methods to control this disease.
    Of course, for the youths, if their naked eyesight dropped significantly, and mostly is less than 0.1, and myopia degree increases 100 to 200 degrees annually, and the patients are with floater, always feel visual fatigue, eye pain, headache, nausea, insomnia, and can not look matter for a long time, etc, we should seek medical advice immediately without any delay.
    The prevention of pathological myopia should begin from parents, doctors and the youths. These three aspects can reduce the incidence of pathological myopia. Even if the diagnosis is pathological myopia, we also can have more time to control the illness and not delay the treatment and then not threaten the bright. So, if it is sure that what the teenagers get is pathological myopia, how to control it?
    In fact, the pathological myopia itself is not terrible at all. The complication it brings to us is the most terrible. Pathological myopia complications include retinal degeneration hiatus and detachment, macular hemorrhage, posterior sclera staphyloma, cataract, glaucoma, amblyopia, strabismus. These complications are the cause of blindness. The control of pathological myopia development is to control the occurrence of complications.
    Frame Glasses can not control pathological myopia development. It only can help us restore the vision, and when the degrees of patients with pathologic myopia degree reach a certain height, frame glasses can´t even play the role of restore vision.
    Ordinary RGP can control pathological myopia development, but the effect is not strong enough. According to clinical statistics, if wear RGP lens, the myopia will increase 48 degrees per year which is far below wear ordinary glasses (every year about 125 degrees), but more than night wear Rigid Gas Permeable Contact Lens for Orthokeratology (4.7 degree every year). For the patients who are with pathological myopia, if the myopia will increase 200 degrees every year, if wear Rigid Gas Permeable Contact Lens for Orthokeratology, it will be only 25 degrees per year. Ordinary RGP lens can not achieve this kind of control effect.
    Teenagers with pathological myopia can not do Laser surgery, and what laser surgery do is just restore vision, and help people get rid of the frame glasses, but can not control pathological myopia development. According to these three aspects, in the field of control adolescent pathological myopia, MCT technology is safe and efficient. Many patients with pathological myopia greatly slow down the myopia development with wearing Rigid Gas Permeable Contact Lens for Orthokeratology, and maintain the long-term stable healthy eyesight.
    The healthy of nationals is the first step of strong country, and the healthy body begins from good vision. Teenagers need more social care, especially teenagers with pathological myopia. Only take good care of them, the undertaking of blindness prevention and treatment will make significant strides, and more people can enjoy the bright.
