Any surgery is an invasive operation, and as long as it is invasive, there are certain risks and complications that may arise, and myopia surgery is no exception. Common complications after myopia surgery include: first, overcorrection or undercorrection, which is relatively common and is related to the repair ability of the cornea, the pre-surgical examination, and the design of the surgical plan. Second, dry eye, especially common, because the surgery changes the refractive state of the cornea, so in the short term it is easy to dry eyes, usually local use of artificial tears can be alleviated. Third, corneal complications such as infectious keratitis, interlaminar debris, and progressive corneal dilatation are usually much less likely to occur. So if you have very high expectations of surgery or are fearful of complications, surgery to treat myopia is still not recommended.
