Restoring vision refers to corrective surgery for myopia, which is divided into two categories: corneal laser myopia correction surgery and crystal implant surgery. Myopic laser myopia correction surgery is divided into full femtosecond surgery, semi-femtosecond surgery and superficial surgery. Full femtosecond surgery uses a femtosecond laser throughout the entire procedure, which is a relatively high-end myopia correction procedure with less trauma and faster recovery. Semi-femtosecond surgery is a combination of femtosecond and excimer laser surgery, which has a faster recovery and minimal trauma, but carries the risk of corneal flap. Superficial surgery is a full procedure using the excimer laser, with a slightly slower recovery, but the postoperative results are acceptable. If the degree of myopia is high or the condition of the cornea does not allow for laser surgery, you can consider lens implantation, which is the implantation of an artificial lens into the eye to correct the effect of myopia. All of these surgical procedures have good post-operative results, and the majority of people will have a significant improvement in their vision, and their vision can be restored to some degree.
