Let's invite Dean Cui Chuanbo, an ophthalmologist from Shandong Lunan Eye Hospital, to introduce us. Does blinking have an effect during myopia surgery? Dean Cui said that generally blinking will not affect the effect, and this possibility will basically not happen. Because the excimer laser equipment is equipped with an infrared eye three-dimensional active tracking system, when your eye deflects beyond the normal range, the excimer laser will automatically stop emitting to ensure the safety of treatment. In addition, in excimer laser surgery, in order to prevent patients from blinking, there is a special eyelid opener to fix the open state of eyes, so blinking cannot occur. In order to eliminate the patient's nervous atmosphere, the doctor not only enlightened the language, but also prepared a pillow for the patient to hold tightly when he was nervous during the operation. This kind of pillow looks unremarkable, but many patients say it is a stress reliever. So patients who want to do myopia surgery can rest assured. 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. As long as the patient can pass the examination, the general operation will be very successful and the effect will be ideal. Excimer laser is a special kind of laser, which will not damage the surrounding tissues like other lasers. Moreover, Lasik surgery is an external eye surgery, which will not hurt the internal eye and will not cause blindness. The key to its safety is strict preoperative examination and evaluation to eliminate all possible contraindications.
