A: Myopic laser surgery has no special requirements for the season because the surgery only takes about 10 minutes, does not require hospitalization, and vision can be restored the day after surgery. Also, laser myopia surgery is performed in a laminar flow operating room with constant temperature, humidity, pressure and 600 air changes per hour, so there is no need to worry about high or low temperatures. Will laser myopia surgery produce after-effects in winter? A: The safety of laser myopia surgery has nothing to do with the season. It is mainly related to the eye condition of myopic friends and the hospital they choose. The surgery is safe because a detailed preoperative examination is done before the laser myopia surgery and contraindications to myopia surgery (e.g., dry eye) are ruled out. Also, choosing a regular hospital is crucial for the safety of laser myopia surgery and the avoidance of sequelae. Besides eye conditions, what are the important factors that determine the outcome of the surgery? A: The effect of laser myopia surgery is mainly related to four major factors: surgeon, surgical equipment, surgical examination, and operating room environment, which are the important factors that affect laser myopia surgery.
