Complications or sequelae may occur after myopia surgery, including early, middle and late complications. The common sequelae are: 1, refractive regression; 2. Correct the shortcomings; 3. Secondary keratitis; 4. Secondary keratoconus; 5, intraocular infection, affecting vision. However, the sequelae of myopia surgery are mostly related to congenital eye diseases that are not suitable for myopia surgery, but they are related to myopia surgery. Therefore, if there is dry eye, conjunctival inflammation, thin cornea, keratoconus before operation, or thin retina with holes, try not to do myopia surgery, and there is a great possibility of sequelae after operation. If the data of myopia examination are normal, the current myopia surgery technology will rarely leave sequelae.
