It is important to know that the implementation and conduct of any surgery is after repeated scientific proof and multi-center clinical trials, myopia laser surgery into the public eye at the beginning, after the United States Food and Drug Administration (FDA) extremely demanding and rigorous approval. Since its introduction into China in 1993, millions of people have had their glasses removed, with an efficiency rate of over 99%. However, with any surgery there can be risks. How great this risk is is as low as the possibility of falling over when walking, and it is all manageable. Excimer laser devices affect accuracy and safety in a variety of ways, with cutting frequency and tracking speed being two important indicators. Increased cutting speed prevents overcorrection due to long exposure of the cornea to air and can be done well for the very few patients who are too nervous, and increased tracking speed ensures the accuracy of laser cutting. We now know that conventional laser surgery is done in two steps, the first step requires the creation of a corneal flap, which can be done with a microkeratome or with a femtosecond laser, which produces a more accurate flap. How it is said is that now we have better options, and it is not that the knife is eliminated. It’s like appendicitis surgery, which used to be a large incision open surgery, but now it’s less invasive and faster recovery with the help of laparoscopy. With the femtosecond laser, the risk of intraoperative accidents is basically eliminated, bringing the safety and precision of surgery to a new level. The second step is to cut with the excimer laser, and today’s equipment is so perfect that you can choose mainstream equipment. Some people are talking about why there are ophthalmologists who also wear glasses. Just like double eyelid surgery, in most cases it is more aesthetically pleasing and beautiful, but we cannot force all people to have the surgery. After all, laser myopia surgery is an elective procedure with the option of wearing glasses, unlike appendicitis where you have to operate without much thought. In fact, more than 30 percent of ophthalmologists in this country opt for myopic laser surgery for family members or for themselves. If a procedure was truly unsafe, it would have been stopped in hospitals a long time ago.
