First, refractive surgery is shallow corneal surgery, which will not directly lead to pathological changes and sequelae of other eye tissues;

Second, careful preoperative examination will be done before operation to ensure that the eyes meet the surgical requirements, and the doctor will perform surgery on the patients;

Third, as long as the doctor's advice is strictly followed during the whole operation, there will be no online rumors about cataract, retinal detachment, eye inflammation and infection caused by myopia surgery.

Fourth, if refractive surgery really leads to serious complications and sequelae, will the country allow this kind of surgery to develop so fast?

Fifth, the laser used in the operation accurately scans the cornea without damaging the internal tissues of the eyeball. Excimer laser belongs to cold laser, which can accurately ablate the desired part of cornea without damaging surrounding tissues and other tissues and organs. Excimer laser has a short wavelength, only 193nm, which can't penetrate the eye at all, so it has no adverse side effects on the internal tissues of the eyeball. There is no reason to have sequelae after several years of treatment.
