Currently refractive surgery technology is more mature, but as an invasive surgery there are some risks, the main risk is the occurrence of some complications such as cone cornea, corneal infection. However, through standardized operation, the incidence of risk is relatively small. Refractive surgery involves cutting the cornea to a certain extent through lasers, etc., so that the curvature of the cornea is altered, thus serving to correct myopia. This type of surgery is invasive and irreversible, and therefore carries certain risks. The main risks are that patients may experience complications such as glare, dry eye, and cone cornea. Refractive surgery is now a relatively mature technology, and complications are generally rare when the patient cooperates in accordance with the code of practice. It is recommended that patients after refractive surgery follow the doctor’s instructions for care, regular review, and timely consultation when discomfort occurs.
