I. What are myopia prevention and control keratoplasty lenses? It is a new type of youth myopia prevention glasses, it is through a physical shaping method, through a reasonable, programmed special design of a rigid keratoplasty lens, night, wear it on the surface of the eye, and then make the cornea in accordance with the reasonable shape we set the deformation, through the corneal shape of the change can make the original myopia, astigmatism of youth some problems to get special effective The purpose of wearing glasses at night is to make the myopic cornea become mildly myopic or not myopic, and during the day, the youngsters’ myopia is reduced or disappears because the shape of the cornea has changed, and if used for a long time, myopia can be controlled to a certain extent, and it can also have the effect of preventing and treating myopia. At present, this is a new technology of the latest foreign research to treat and prevent the aggravation of myopia, especially for the control of myopia in teenagers is a very good technology. Second, what is the principle of corneal shaping lens? Generally speaking, soft things will change shape with hard things, our eye cornea is soft, myopia prevention keratoplasty lens hardness than the corneal hardness is higher, so in the process of wearing the lens, will gradually through physical methods to make the cornea a change in shape, this phenomenon is actually the principle of ophthalmology scientists to invent keratoplasty lens, foreign countries in recent years with this method of corneal production A reasonable shaping treatment to prevent and control myopia. Will keratomileusis have any side effects on my eyes? Long-term use of keratoplasty will not cause any special adverse effects on the eyes, but the prerequisite for safety is to wear them in accordance with the doctor’s instructions and under the premise of scientific and standardized use, which can achieve a safe and effective effect. Therefore, rigid keratomileusis is a safe and effective way to prevent myopia in young people. Fourth, who is suitable for wearing rigid keratomileusis? 1, children and adolescents do not have good results using frame glasses, myopia is growing rapidly 2, myopia, astigmatism, especially children with high refractive error 3, parents with high myopia, children have a tendency to inherit 4, in the treatment of myopia optical lenses it is the best quality and the most advantageous. Can students wear rigid keratomileusis? At present, the treatment of keratomileusis is mainly for adolescent myopia, for example, around 9 years old, until about 18 years old, this age myopia is the fastest growing stage, some children may grow 100 degrees or even 200 degrees per year, such children are not given control, it is easy to develop into high myopia, high myopia on future learning, employment, etc. have a negative impact. Therefore, for adolescent myopia, ophthalmologists advocate early control and early intervention. At present, there are many ways to prevent myopia in adolescents, but in general, international ophthalmologists generally recognize the project of myopia treatment with corneal shaping lenses. Is it safe to wear rigid keratomileusis? The prerequisite for safe eyewear is that it must be used under the guidance of an ophthalmologist, and there is a scientific procedure for fitting and use in a regular hospital. Regularly go to the hospital to receive the optometrist’s review and maintenance, so that for children and adolescents, it is safer. Myths: Is it possible to cure myopia by wearing keratomileusis at the child stage? So far, there are many methods to prevent and control myopia, but none of them can cure myopia, and keratoplasty can’t cure myopia completely, but if used reasonably and in a timely manner, it can have a significant controlling and delaying effect on the development of myopia in adolescents when they wear the lenses for a long time. If the child wears the lenses for a period of time, the vision recovers well, and then stops wearing the lenses, the cornea may bounce back, resulting in myopia control failure, and then it is necessary to insist on wearing the lenses to consolidate the effect. Myopia that has already occurred cannot be eliminated by wearing keratoconstrictive lenses. For children with increased myopia, the annual growth rate of myopia may be greater with ordinary frames, but the growth rate of myopia with keratomileusis is only about one-half of that with frames, or even lower. The clinical indicators show that keratoplasty is effective in delaying and controlling myopia.
