Laser surgery methods mainly include the following:
1, Full Femtosecond Laser Surgery: This kind of surgery is completely completed by femtosecond laser. The operation uses femtosecond laser to scan the corneal layer twice to form a lens, and then the lens is taken out through a micro-incision to complete the operation. Its biggest advantage is that it does not need to be a corneal flap, and there is no need to worry about the risk of corneal flap displacement caused by eye trauma.
