Principles of myopia correction surgery

After myopia occurs in the eye, it can be corrected by surgery. The general surgical method can be divided into two kinds. One is corneal refractive surgery, which is to cut the cornea of myopic patients through excimer laser. The higher the degree of myopia, the more the cornea is cut, which can change the refraction of the cornea and improve myopia. The other is intraocular lens implantation surgery, which is to implant an intraocular lens with myopia degree in the patient's eye and propose to improve vision.
