The safety of myopic surgery is relatively good. If the surgery fails, there is a possibility that the visual function may be affected, but with timely treatment, it usually does not cause blindness. Myopic surgery consists of two major types: laser surgery and posterior chamber IOL implantation for crystalline eyes. Both types of surgery are very mature and safe, but there are still risks, such as secondary glaucoma, secondary cone cornea, and infection. Once a myopic surgery complication occurs, timely and aggressive treatment can keep the complication under control, thus promoting recovery and minimizing the impact on vision, and blindness is not very likely. However, if the patient does not pay any attention to the complications, neither examining nor treating, and eventually the complications develop to a more serious degree, there is also the possibility of blindness. Failed myopic surgery should be taken seriously and treated actively with the doctor.
