It is recommended that the first option is keratomilecular refractive surgery, including excimer laser surgery and femtosecond laser surgery, because this surgery corrects myopia by changing the thickness or radius of curvature of the cornea, so the correction effect is ideal for myopia that meets the indications. Intraocular refractive surgery can also be considered, including the usual ICL surgery, which is an IOL implantation for crystalline eyes. This surgery can also be used to correct 800 degrees of myopia, and the principle of the surgery is to reimplant an IOL on the surface of the normal lens, which can change the refractive state of the eye to correct myopia. The choice of surgical method depends on the results of the specific examination, and only then can you choose the most suitable method for you.
