The choice of whether or not to have surgical correction for 300-degree myopia should be based on your needs and whether or not you are eligible for surgery. Surgery is a good choice for myopic people who have a strong need for lens removal. Myopia surgery should be considered only after the number of adult years has stabilized. Pre-operative examination should be completed to meet the conditions for surgery, such as corneal thickness, no active inflammation in the eye, and good general condition. If there is a need for surgical correction of myopia, it is recommended to go to a regular hospital to ensure safety and effectiveness. Surgical correction is only a change of the current refractive state, after surgery, you still need to pay attention to eye habits to avoid vision regression.
