Surgical treatment for myopia is a routine procedure in ophthalmology, so this surgery is not dangerous. Many people are intimidated by the procedure because they do not understand it. In fact, the principle of this surgery is relatively simple. Regardless of the surgical method, the principle is to correct refractive error by changing the refractive state of the eye or cornea. There are two types of surgical procedures: the first is excimer laser surgery and femtosecond laser surgery; the second is intraocular refractive surgery, which includes IOL implantation and lens replacement for crystalline eyes. As long as these surgeries are done in a regular hospital, there are some small probable risks or complications, but they are all within the controllable range and do not affect the treatment of the surgery. Therefore, surgery can be considered if myopia is present in the eye.
