Myopia surgery generally refers to refractive surgery to correct myopia. The advantages of myopia surgery are that it allows patients to stop wearing glasses and restore their vision to normal levels; the disadvantages are that it may lead to a decrease in night vision, cause dry eyes, and so on. Myopia surgery, also known as corrective myopia surgery, is mainly for people over the age of 18 with stable myopia. It allows patients to stop wearing eyeglasses and restore their vision to normal level. However, some patients may experience symptoms such as decreased night vision, dry eyes, etc., and a few patients may also experience double vision and refractive error after the surgery. Myopic surgery is not suitable for patients with acute conjunctivitis and keratitis, as well as people with keloid, diabetes mellitus, proptosis, one eye, etc. It is recommended to follow the doctor’s instructions strictly to take good care of your eyes after the surgery, to develop good eye habits, avoid overuse of the eyes, and to pay attention to monitoring the eye condition in your life, and to seek medical treatment in time once you experience any ocular discomfort or visual impairment.
