There are many kinds of operations for myopia, and the specific procedures of different types of operations are also different. Common myopia operations include corneal refractive surgery and intraocular refractive surgery. Corneal refractive surgery is divided into femtosecond laser surgery and excimer laser surgery. The operation process is to manually cut the corneal surface layer or corneal stroma layer, adjust the corneal thickness or corneal curvature radius, change the refractive state of the eyes, and achieve the purpose of correcting vision. Intraocular refractive surgery mainly includes lens replacement and intraocular lens implantation. Lens replacement is mostly used for myopia complicated with cataract, and the lens is removed and replaced with intraocular lens. Intraocular lens implantation is to implant an intraocular lens on the surface of a normal lens to change the refractive state of the eye.
