Myopic surgery includes corneal refractive surgery and intraocular refractive surgery, which may cause sequelae such as dry eyes, keratitis and cone cornea. 1. Dry eye: Myopic surgery is cutting the surface of the cornea, and this change will cause some damage to the tear film on the surface of the cornea, and dry eye is easy to occur after surgery. Artificial tears can be used to relieve dry eyes. 2. Keratitis: Keratitis may occur after myopic surgery on the cornea cutting, which destroys the integrity of the cornea. It can be treated with drugs such as levofloxacin and ganciclovir depending on the type of infection. 3. Conical cornea: Certain patients have thin corneas, and the thickness of the cornea thins further after myopic surgery, resulting in conical cornea. It can be treated by corneal transplantation. Some sequelae after myopia surgery can be avoided, and it is recommended that patients go to professional eye institutions for surgery, and take medication according to the doctor’s instructions and have regular checkups after surgery.
