Surgery to restore vision is mainly focused on corrective surgery for myopia, which is usually divided into corrective laser surgery for the cornea and crystal implant surgery. Corneal laser surgery is divided into three categories: full femtosecond surgery, semi-femtosecond surgery and superficial surgery. Full femtosecond surgery is a high-end surgery that uses a femtosecond laser throughout the entire procedure, which is relatively less invasive and faster to recover, and is the more recommended procedure. Semi-femtosecond surgery is a combination of femtosecond laser and excimer laser surgery, which is also faster and less traumatic, but there is a risk of corneal flap, and if there is a violent impact after surgery, it may lead to flap displacement and dislocation. Superficial surgery is the use of excimer laser for the entire procedure, which is less expensive, but more traumatic, slower recovery, may require medication for 3-6 months, and is more suitable for patients with low myopia. IOL implantation is a type of intraocular surgery for highly myopic patients or those who are not allowed to undergo laser surgery. It is an intraocular surgery in which an IOL is implanted into the eye to correct myopia, but there may be a risk of intraocular infection or cataract and glaucoma.
