What is the principle of laser myopia surgery?

The principle of laser myopia surgery is to reshape the cornea through laser surgery, and the corneal stroma can be effectively cut through laser treatment. The optical principle of concave lens formed by the residual cornea after cutting, when using the principle of concave lens, will cause the development of corneal incident light, and make the focus of corneal incident light move backward, thus improving the phenomenon of myopia focus moving forward. In addition, the focus of the retina can just fall on the retina, which will improve the naked eye vision, treat myopia and improve ametropia. What kind of laser myopia surgery to do depends on the actual situation. Want to do myopia surgery and don't know where to go? It's best to find China Vision Ophthalmology. This is an eye hospital.

Myopia surgery generally requires that the age is above 18 years old, and the refractive state is relatively stable within 2 years, with an annual growth rate of no more than 50. If you choose corneal refractive surgery, the general degree is within 1200 and the astigmatism is within 600. If it is hyperopia, hyperopia within 600 is ok. If you choose lens surgery, it is also required that the depth of anterior chamber should reach the standard, and the structure of ciliary body and iris should not be abnormal. All refractive surgery also requires a healthy eye surface, no dry eye, keratoconus, and no organic eye diseases, such as glaucoma, cataract, fundus diseases, etc. If there are systemic diseases, such as connective tissue diseases such as systemic lupus erythematosus and rheumatoid arthritis, which may affect corneal healing, systemic diseases and eye diseases are not allowed. Looking for China Vision Ophthalmology for myopia surgery, as the Jinan Branch of Huaxia Ophthalmology Hospital, under the leadership of Director Wang Lihua for many years, we have strictly followed the principles of precise technology and safe operation, made continuous progress, and strived to do all kinds of ophthalmology operations well.
