How many corneas are cut after myopia surgery, 100 degrees = how many, and how many corneas are kept at least? How many years can vision be stable? Thank you! !

Usually in the case of myopia, it is relatively stable within two years, and the floating degree of myopia will not exceed 100 degrees. You can go to laser surgery. Moreover, you must choose a regular hospital to do laser surgery, and you need to do a comprehensive examination before doing surgery. You can't operate until you are sure everything is normal.

Generally, the corneal thickness of myopia surgery is less than 4 10, and that of ordinary people is about 460 μ m ~ 650 μ m. Myopia surgery can be divided into laser surgery and intraocular lens implantation, in which laser surgery needs to remove part of the cornea to achieve the purpose of taking off glasses.

100 degree needs to be cut about 20 microns, and every 100 degree needs to be cut 10- 14 micron. The safe range of corneal bed thickness is not less than 280 microns. Vision needs to be stable 1 year or more.

At present, the age requirement for surgical treatment of myopia is generally over 18 years old, and the myopia degree is required to be stable for two years. In the past two years, the growth rate should not exceed 50 degrees. Only in this way can the refractive state of the eyes be stabilized and surgery can be considered.
