Xiao Min is an excellent child, not only does she excel in her studies, but she has just won the second prize in the national piano competition. However, while the whole family was sharing the joy, her mother found out that Minnie’s eyes were nearsighted, and they were already 200 degrees. On the one hand, the piano study cannot be relaxed; on the other hand, the myopia of the eyes is getting deeper and deeper, which really makes the mother at a loss. Wearing glasses is certainly a solution, but every year there will be an increase of 50 to 75 degrees, and it is not beautiful to attend performances. Is there a way to correct myopia and control its development? ”The introduction of keratoplasty lenses has made the dream of myopic children to get rid of their glasses come true, and its biggest advantage is that it can control the development of myopia. According to a clinical study at Peking University, patients who applied keratoplasty lenses increased by 8 degrees per year, while those who did not applied them increased by 67 degrees per year. The principle of myopia correction with keratoplasty lenses lies in the fact that the inner surface of the lens is composed of several curved segments and the tear layer between the lens and the cornea is unevenly distributed. The resulting hydrodynamic effect changes the geometry of the cornea, flattening the center and shortening the eye axis, thus reducing or even eliminating myopia. These lenses are suitable not only for children and adolescents under 18 years of age, but also for other patients with low myopia who are not suitable for refractive surgery. It is similar to normal contact lenses in terms of fitting and maintenance, and it is easier to clean and more durable, generally each pair of lenses can be worn for 2 to 3 years. The only difference is that it is worn at night, unknowingly treating myopia in your sleep and bringing your daytime naked eye vision to 1.0.
