The diopter has been stable in the past two years (its development rate is no more than 50 degrees per year). Supplementary note: if the age and diopter are within the range of treatment, a detailed preoperative examination is required to see whether other conditions of the eye meet the requirements of the operation.

Generally speaking, not wearing glasses after operation is equivalent to the best vision after wearing glasses before operation. The doctor can predict your postoperative vision according to the examination results.
myopia will not rebound after operation. The rebound that people usually complain about, It is mainly due to: (1) the patient did not take the medicine according to the doctor’s advice after the operation, felt that his eyesight was very good, and stopped the medicine in advance. (2) the individual differences of the patients. A very few corneal healing reactions were particularly strong, which may cause regression. However, if they were rechecked in time and found out in time, the doctor would take measures to prevent rebound.
