Is it safe to have myopia surgery? As most people know, there are risks associated with any surgery, and no one can guarantee that it will be foolproof, but the so-called risks are only relative. Many people think that trains are safer than planes, and in fact, planes are safer than trains. In fact, this is only related to the media reports, did not hear or see the natural will not be concerned, so the mind over time formed the concept of aircraft than train accident prone. To get back to the point, is it safe to have myopia surgery? First of all, the laser used in excimer laser treatment for myopia is a cold laser that can precisely ablate the part of the cornea that is expected to be removed without damaging the surrounding tissue and other tissues and organs. Patients should pay close attention to this point. Laser treatment for myopia is currently the most effective treatment for myopia. Therefore, for ophthalmologists with a long history of surgery and very extensive experience, the risk of surgical treatment of myopia may not be higher than wearing contact lenses. Secondly, after nearly 20 years of clinical application, the technology of excimer laser surgery for myopia has become very mature and safe, and as long as the preoperative examination excludes contraindications to surgery and other, the effect of laser treatment for myopia is also stable. In particular, femtosecond laser technology is the leading edge technology in ophthalmic laser science today. And the technology has successfully passed the test of NASA and NASA, and is used by the United States for American astronauts. I believe that through the above introduction, we all have a better understanding of excimer laser surgery for myopia, the excimer laser treatment center of Tianjin Medical University Eye Hospital warmly suggests that before the excimer laser surgery we try to understand the hospital’s equipment, inspection instruments and the degree of surgery, so that they are fully prepared for the surgery.
