Femtosecond laser myopia surgery is relatively mature and safe at present, generally there is no obvious after-effects, but unreasonable use of eyes after the operation and failure to do a good job of daily care may lead to postoperative dry eyes, myopia rebound and other phenomena. 1. Dry eyes: Femtosecond laser surgery will cause dry eyes in the short term. The cornea’s perception during the operation has not been restored in the short term, and the tear secretion is relatively small, so the phenomenon of dry eyes will occur. 2. Nearsightedness rebound: In the short term after the completion of surgery, excessive use of electronic products, excessive eye use or improper eye use, etc., may cause myopia rebound. Therefore, you must pay attention to your eyes after the surgery and take good care of your eyes so as not to affect the recovery of your eyes. After the completion of the femtosecond laser myopia surgery, you need to follow the doctor’s instructions to do a good job of care and follow-up, when there is obvious discomfort, it is recommended to go to a professional eye hospital in a timely manner to consult the treatment.
