1.Q: What is keratomileusis? Flogging: It is a non-surgical method of correcting myopia by wearing a rigid corneal contact lens at night. 2.Q: How do keratoplasty lenses treat myopia? What is the principle of treatment?

By using the memory of the corneal shape, the central part of the cornea remains flat for a certain period of time after the lens is removed. When the cornea is flattened, the focal length of the eye is lengthened, which allows the focus of the incoming light from the front of the fundus of the myopic eye to move just to the retina, thus achieving the purpose of treatment. 3.Q: Who are the main users of keratomileusis?
