Myth 1: Laser myopia surgery has sequelae and safety risks Any surgery has certain risks, surgery requires good cooperation between doctors and patients; laser myopia surgery in China has 20 years of development, technology, equipment continues to develop, improve, clinicians are increasingly experienced, laser myopia surgery, especially femtosecond laser myopia surgery is very mature, safe surgery. The comprehensive preoperative examination strictly screens for contraindications to surgery, while strictly grasping the range of indications, which has reduced surgical complications 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, changing the curvature of the cornea, so that light can be focused on the retina, so as to achieve the purpose of correcting myopia. Therefore, the scope of correction is closely related to the thickness of the cornea; patients with ultra-high myopia of over 1200 degrees often have a certain amount of degrees remaining in the case of safe corneal thickness reserved after surgery. Therefore, patients with more than 1200 degrees should generally not undergo surgery and should consider ICL lens implantation instead. Myth 3: There is no age limit for laser myopia surgery Patients under 18 years old with myopia often have an unstable refractive state and their myopia may deepen further; patients over 50 years old with myopia often have old vision and may have a combination of crystal clouding, which can be corrected in cataract surgery at the same time. Therefore, not all myopic patients of all ages are suitable to receive laser myopia surgery. Myth 4: Laser myopia surgery can only treat myopia but not astigmatism Patients with myopia often have a certain amount of astigmatism combined with laser myopia surgery. However, it should be noted that due to the instrumentation, currently only up to 600 degrees of astigmatism can be corrected. Myth #5: Vision can reach 1.5 after laser myopia surgery The human eye is a fine refractive system composed of cornea, lens, vitreous, retina, etc. Any tissue lesion or defect will cause damage to vision. Differences in vision for each individual are often due to differences in the refractive system of the eye as a whole; it is difficult to completely adjust the refractive state of the entire eye by merely adjusting the corneal refraction. Therefore, in general, laser myopia surgery can help patients achieve preoperative corrected visual acuity, but not the luxury of having 1.5 vision for all.
