Myopia can also occur after femtosecond surgery if you are not careful with your eyes. Femtosecond surgery is only a method of correcting myopia and can serve to correct refractive errors, but do not rely on it excessively. Femtosecond surgery, one of the main types of corrective surgery performed on people over the age of 18 who have a more stable visual condition, corrects the myopia at the time of the surgery, and can play a role in preventing and controlling myopia afterwards. Vision will be in a more stable state as an adult, but there is no guarantee that myopia will not recur after surgery. Even if your vision is corrected by femtosecond surgery, you will still have more or less myopia if you keep the bad habit of working and studying close to your eyes for a long time. The prevention and control of myopia cannot be overly dependent on one party or one measure. Not only effective external interventions, but also the cultivation of one’s own eye habits, genetic factors and other factors are very important.
