Common Myths about Myopia Laser

Myth 1: Laser myopia surgery has sequelae and safety risks Everything has a certain risk, just like we take the airplane train. Surgery requires good cooperation between the doctor and the patient. Laser myopia surgery has been developed for more than 20 years in China, with continuous development and improvement of technology and equipment, and increasingly experienced clinicians, laser myopia surgery, especially femtosecond laser myopia surgery, is a very mature and safe surgery. Comprehensive and meticulous preoperative examination strictly screens for contraindications to surgery, and at the same time strictly grasps the scope of indications, so that surgical complications have been reduced to a very low level. Myth 2: Any degree of laser myopia surgery can be corrected Laser myopia surgery is a kind of corneal surgery, the principle of which is to excimer laser cutting corneal stromal tissue, change the curvature of the cornea, so that the light can be focused on the retina, so as to achieve the purpose of correcting myopia. Therefore, its corrective range and corneal thickness are closely related; patients with ultra-high myopia of more than 1,200 degrees will often have a certain amount of myopia left in the case of safe corneal thickness reserved after surgery. Therefore, patients with more than 1200 degrees of myopia are generally not suitable for surgery, and should consider ICL lens implantation. Myth 3: There is no age limit for laser myopia surgery Myopia patients under 18 years of age, the development of refractive state is often still unstable, myopia may further deepen; myopia patients over 50 years of age, often have old eyesight, and may be combined with crystalline clouding, which can be corrected at the same time in the cataract surgery myopia, astigmatism and other conditions. Therefore, not all age groups of myopic patients are suitable to receive laser myopia surgery. Myth 4: Laser myopia surgery can only treat myopia but not astigmatism Myopia patients are often combined with a certain degree of astigmatism, generally speaking, laser myopia surgery can be used to correct myopia and astigmatism at the same time. However, it should be noted that, due to the reason of instrumentation, the current general can only correct astigmatism within 600 degrees. Myth 5: Visual acuity after laser myopia surgery can reach 1.5 The human eye is a fine refractive system composed of cornea, lens, vitreous humor, retina, etc., and any one of these tissues that are diseased or defective will cause visual impairment. The difference in each person’s vision is often due to the differences in the refractive system of the eye as a whole; it is difficult to fully adjust the refractive status of the entire eye by merely adjusting the corneal refraction. Therefore, in general, laser myopia surgery can help patients to achieve preoperative corrected vision, but not the luxury of 1.5 vision.
