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

    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.

    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.
      (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.
    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.
    Table 1      The comparison of eye axis before and after wearing Lens (mm)

    2.Grouped by different degrees of myopia, there was eye axis changes comparison: low myopia and moderate. One month after wearing, there were eye axis growth differences. It was statistically significant. For moderate myopia group, its axis was obviously slower growth. Shown in table 2.
    Table 2      The eye axis changes (mm) of moderate myopia group and low myopia group eye

    3.The changes of Eye axis of younger age and older age shown that each group has no statistically significant difference. Shown in table3.
    Table 3      The axis changes (mm) of younger age and older age



      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.

    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.   

    [Key words] MCT; adolescent; myopia     

      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.
      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).

    Successful Cases of MCT Technology for Subclinical Keratoconus
    Case No. 1:
    Patient´s Problem: Subclinical Keratoconus

    Topographic Map before Wearing Rigid Gas Permeable Contact Lens for Orthokeratology
    Topographic Map When Wearing Rigid Gas Permeable Contact Lens for Orthokeratology
    Early Diagnosis of Sub-clinical Keratoconus Makes You away from the Threat of Blindness

      Eye, it is the brightest part of human body. With it, we see the world and enjoy happiness. In daily life, we take considerate care to our eyes: we will go to hospital, if get eye diseases; we will try to restore vision, if our vision is not clear. So, speaking for itself, our eyes are so important.  

      The major function of our eyes is to provide us good vision. Myopia and some other bad vision problems are the killers of eyes. They will influence our visual quantity and bring us some troubles. But as a matter of fact, myopia is not the most horrible one. Most of vision problems will not put our eyes under the threat of blindness. We are most worry about blindness: once it happens, even the rebirth of great doctor Hua Tuo, the probability of reversal is very little.

      This is not alarmism! Every year countless people get blindness which is led by Cataract, Glaucoma, Macular Degeneration or Retinal Detachment. Above are our familiar ones, and there are also some diseases which will cause blindness and we do not know. They get closer slowly and quietly, liking Keratoconus, and bring your bright away. They are the invisible killer of our vision.

      Keratoconus, a difficult problem in the field of ophthalmology, is with a complex pathogenesis and a difficult treatment. And the more serious one is that keratoconus is with an incubation period. If we do not diagnose keratoconus in the incubation period, once get clinical diagnose, there will be with a huge pressure to its treatment, because keratoconus will bring blindness. So, what is it?  

      Keratoconus is a kind of eye disease whose feature is the thinning and conical forward protruding of the central cornea. It can be divided into anterior Keratoconus and posterior keratoconus. Usually, it will cause high myopia, high irregular astigmatism and visual damage in different degrees but without any inflammation. Keratoconus mostly happens among youths who are about 20 years old and commonly both eyes will get this disease successively.

      Although there are many experts studied in keratoconus, but the pathogenesis of it is still unknown. Histological speaking, we found fiberboard layer reduced in conical part, but the diameter of collagen fiber does not change. So we can regard that the pathogenesis is the bonding of fiberboard layers is not enough, layers are mutual slippage, and this leads the thinning. Genetic and allergic diseases are also the possible causes. Because progressive thinning of the corneal center, the degree of irregular astigmatism increases, and myopic degree also develops ceaselessly, vision ability progressively declines. This serious influences life, work and learning, and with the disease´s developing, it may cause corneal perforation, and even blindness which can be only solved by corneal transplantation.

      Just like the diseases in other part of our body, the earlier diagnosis it is, the easier treatment it needs. If we can confirm the diagnosis of keratoconus in subclinical period, we can earn more time for the treatment. The key of the treatment of keratoconus is doing the diagnosis in subclinical period.
    “What is subclinical keratoconus? It is a kind of suspected keratoconus which is without clinical diagnosis. The sufferers are not aware that they get keratoconus, because they may be with myopia, high myopia and some other vision problems at the same time, and their treatment is also only for myopia. This lets they miss the best treatment period of keratoconus.” This is the yearly ophthalmology & optometry practice experience from Professor Wang in Shanghai Furen Ophthalmology Technology Research Institution and Web Optometry Research Institution.    

      Just liking Professor Wang, Many ophthalmologists have such experience. They know the importance of the early diagnosis of keratoconus which brings the greater hope for patients to get normal vision and reduces the risk of blindness. Once get blindness, what be destroyed are not only a person, but also a family.   

      Then, how to know if get keratoconus when it is during sub-clinical period? This is a question after which there are the unrimitting efforts from thousands of ophthalmologists. Yes, it is hard to diagnose sub-clinical keratoconus, but not no way.

      MCT, a kind of corneal reshaping technology, get a huge breakthrough in the treatment and correction of vision problems, and after yearly constant innovation, it also bring good new in the early diagnosis of sub-clinical keratoconus. And how does it work?  

      The patients with sub-clinical keratoconus commonly will be with myopia and some poor vision problems. If they are in the process of use of MCT, when doctors do topographic map and collect their data, it will be found that their K values in corneal surface are abnormal, and then patients and physicians need to pay attention to the possibility of keratoconus. This is the first test, but this test is not enough to preliminary diagnose clinical keratoconus, and what can do it is MCT technology.

      Professor Wang is the original designer of MCT technology, and he said MCT technology has completely digitized, is able to do accurate analysis of the data from corneal surface, and finds the abnormal situation of corneal surface. But MCT technology is not limited to the first test; it also developed a more accurate differential diagnosis method.

      The differential diagnosis of clinical keratoconus needs to insist. After the digital corneal topography, myopic patients whose K values of corneal surfaces are abnormal wear Rigid Gas Permeable Contact Lens for Orthokeratology to correct their eyesight, after 6 months’ wearing, the effect is good, and the cornea is health, we can eliminate the possibility of subclinical keratoconus; Conversely, if after 6 months, it does not work well and the corneal is not healthy, we can preliminarily diagnose that it is subclinical keratoconus. Of course, the premise is that patients listen to what doctor said, do the review timely, and do the daily lens care and eye care well.

      This is not a complex differential diagnosis method of subclinical keratoconus, but it is the result of the long-term innovation research and service from Professor Wang and other first-rate ophthalmologists. Seemly, it is a small step, but for more patients with subclinical keratoconus, it means the more opportunities of treatment, and means the hope which can help patients not to blind. This is contribution in the prevention and treatment of blindness, and also the success in the solvation of human eye problem.

      Keratoconus is terrible because it’s difficult diagnosis and treatment. It may need surgery, and be easy to blindness. The early differential diagnosis of subclinical keratoconus is equivalent to avoid this disease in the cradle period, and do not let it develop into the vision killer. So, the eye does not need to face to the threat of blindness any longer, and many save the hope of vision.

      As the creation of the differential diagnosis of subclinical keratoconus, MCT technology firmly believe that only unremitting efforts can help more people enjoy healthy and good vision, and the prevention and treatment of blindness is a long road which need more people to make concerted effort.        

    The myopia correction by MCT Technology can partly instead of laser surgery

    As one of the most important part of our body, a pair of bright eyes can bring us a colorful world and a bright future. Bright eyes should not only have a beautiful appearance, but also have a good vision. Actually, good eyesight is much more important than beautiful appearance. In the daily life, the girls like to use eye line, eye shadow, eyelash to beautify their eyes but once when vision lost, even having the external beauty, bad vision will bring a variety of troubles, and you have to wear glasses or do surgery to correct the vision.
    There commonly have two ways to correct the refractive error, Wearing a frame glasses and contact lenses. Mild-to-moderate myopia usually can correct and treat the refractive error by frame glasses. This is also the main treatment for simply mild-to-moderate myopia at present. Contact lenses usually suits for high myopia, astigmatism, amblyopia and pathological myopia, etc. Lens correction is suitable for the correction and treatment of the developing myopia and steady myopia.

      Surgically correction of refractive error is based on the laser, and the most common surgery is LASIK and femtosecond laser surgery. Laser surgery have more obvious effect on solving some bad vision problems, but it also faces with a certain risk, including its own risk and risk of postoperative complications. The operation has stability, and in addition, there also have some certain requests to patients. Not all the patients can use the surgery to solve the vision problems.

      Many domestic and foreign ophthalmology & optometry research institutions are in continuous efforts in finding a non-operative way to solve various vision problems, but also ensure the effect, and the lower risk. They has already made some achievements, the earliest one is the Orthokeratology lens. Traditional Orthokeratology lenses can correct and treat mild myopia and some other vision problems, but in actual applications, because of the risk of trial fitting, it leads to keratitis and some other complications after wearing. The most serious complication is blindness. It makes a lot of patients have the psychological burden. Although development is difficult, a kind of corneal reshaping MCT technology came out. It transcends the traditional orthok lenses, avoids the risk of trial fitting, and also achieves as same effect as the surgery.

      MCT technology is the Corneal Reshaping technology developed by Web Optometry Institution, Shanghai Furen ophthalmology technology research institution and numerous national ophthalmology and Optometry research institutions. After 14 years´ development, it becomes a leading corneal reshaping technology among the world. MCT technology is based on individual cornea. It collects the 6000 ~ 10000 data in the corneal surface, and designs the lenses according to the like-holographic data. The Rigid Gas Permeable Contact Lens for Orthokeratology reversely stops axis growth directly by the focus of upper eyelid, revises corneal radian, avoids the forward protruding of cornea, makes the cornea plain, and reduce the degree of myopia. It has an obvious effect on children and teen-agers myopia, high myopia, astigmatism, presbyopia, adult amblyopia and some refractive errors.

      Although MCT technology and laser surgery are not the same correction method, the principle of the treatment is the same: reasonably changes the shape of corneal surface, reduces the refractive power, and then reduces or even eliminates myopia. MCT technology can do what the surgery can do, and also can do it can not do.

      Comparing with laser surgery, MCT Technology has lower risk in the filed of the correction of vision problems. After clinical test, MCT technology became more and more popular among patients with vision problem. After 10 years development, there are tens of thousands of MCT members and the success rate is 99%. Meanwhile, there are the risk of over and under correction, dry eyes and some other problems after surgery.

      Laser surgery is mainly used for myopia which stops the development, but if it is in the development, the physicians will remind the patients not to do the surgery correction. MCT technology is mainly used for the developed myopia. Because it can more effectively control the development and correct the vision.

      Without correct nursing, or because of some other reasons, it may lead to refractive error recovery after surgery. This makes the surgery cannot have a long-term vision effect; but MCT technology can be worn in the daytime and at night. And after a whole night wearing, it will still have a good vision after taking off the lens during the day.

      For pathological myopia, laser surgery is difficult to obtain a good result. After a period of time, the degrees of myopia will increase for pathological myopia patients who did the laser surgery. And complications will continue to develop. MCT technology can reduce the development of the degree increase of pathological myopia, indirectly prevent the development of complications, and does not need to assume surgical risk. In the field of pathological myopia, MCT technology is better than the laser surgery.

      Use MCT technology to correct the refractive error, avoid the risk of laser surgery, and enjoy the good eyesight. MCT technology lets more people share the light!
