Myopia surgery mainly consists of corneal laser surgery and crystalline lens implantation. Myopia surgery can be performed on patients as young as 40 years of age if the patient meets the criteria for surgery and has a strong desire to undergo surgery. Myopia surgery is a type of surgery to correct myopia, and there are certain requirements for the age of the patient, usually over 18 years old. If a 40-year-old patient meets the criteria for myopia surgery and has a strong desire to be disfigured, he or she may be able to undergo surgery to correct his or her myopia and improve his or her vision. However, not all people are suitable for myopia surgery, and age is not the first element to be considered for surgery. When the patient has eye diseases, such as keratitis, glaucoma, conjunctivitis, etc., the patient can not immediately perform myopia surgery, and need to treat the eye diseases in a timely manner, or the likelihood of post-surgical complications is high. It is recommended that myopic patients should consult a doctor in time to assess their condition and choose the appropriate treatment under the doctor’s guidance.
