The correction performed by myopia surgery is usually adequate correction, so after myopia surgery without myopic regression or improper aftercare, the patient is usually orthoptic and usually has no myopia. Since patients will perfect the measurement of detailed data such as corneal topography, optometry and eye axis length before undergoing myopic refractive or IOL implantation and other surgeries for myopic correction, they will be sufficiently corrected when the conditions are sufficient, that is, after the postoperative recovery period, patients can achieve a visual acuity of 1.0 and above without glasses, and are in an orthoptic state. However, in the case of myopia has not yet stabilized the degree of surgery or postoperative care is not appropriate, in a certain period of time, the refractive surgery eyes myopia will occur back to the phenomenon, thus showing a certain degree of refractive error. It is recommended that after myopia surgery, patients should follow the doctor’s instructions for care, regular checkups, timely consultation after discomfort occurs, and reasonable treatment in accordance with the doctor’s instructions.
