The indications for laser surgery to treat myopia are generally the following: First, adults over the age of 18 years old. Second, the degree of myopia is generally required to be within 100-1500 degrees, and the degree of myopia is stable within two years, with a change of less than 50 degrees per year. Third, the curvature of the cornea is required to be 39-48D, and the thickness of the cornea should generally exceed 460 microns. Fourth, the eye cannot have glaucoma, high intraocular pressure disorder, or dilated pupil. Only if these conditions are met can you choose laser surgery to correct myopia. The common surgical methods include excimer laser surgery and femtosecond laser surgery, both of which are ideal for effectively correcting myopia and improving vision.
