Myopia surgery is divided into many different methods, and different methods have different indications, so only what is suitable for you is the best method. At present, it is generally believed that for myopia within 1200 degrees, the first choice is keratoconus surgery, which is the most suitable method. Corneal refractive surgery mainly includes excimer laser surgery and femtosecond laser surgery, which means cutting the stromal layer of the cornea by these two means, thus changing the curvature of the cornea or corneal thickness, through which myopia can be corrected and vision can be improved. If the degree of myopia is relatively high, such as 1000-2000 degrees, you can consider intraocular refractive surgery, that is, ICL lens implantation.
