How much vision can I achieve after LASIK surgery? The results of the surgery have been excellent, with the vast majority of patients having their heavy myopia glasses removed once and for all. The post-operative visual acuity is usually as good as the pre-treatment corrected visual acuity with lenses. A national expert wrote “Socio-medical and Psychological Analysis of LASIK Surgery”, stating that 98.82% of people feel very satisfied or satisfied with the surgery after LASIK. However, the amount of vision you can ultimately achieve depends on your preoperative best corrected vision, the level of refraction, your own response to laser treatment, your own recovery, and other factors. Based on our 16 years of surgical experience, if your preoperative corrected visual acuity is good, your postoperative vision is basically above 1.0. Long Qin, Peking Union Medical College Hospital Ophthalmology Department Will there be any after-effects of laser treatment for myopia? Excimer laser is a fluorine-argon gas mixture produced by excitation of an ultraviolet beam invisible to the human eye, which is a cold laser that can precisely ablate the part of the cornea expected to be removed without damaging the surrounding tissue and other tissues and organs. The excimer laser has a very short wavelength of 193 nm (nanometers) and cannot penetrate into the eye; therefore, there are no adverse side effects on the internal tissues of the eye. There is also no reason for after-effects to occur after several years of treatment. Can I have laser myopia surgery for frequent computer use? This question is universal. There are too many people in our society who use computers regularly, and we have done a lot of myopia surgery for people in the IT industry, and the feedback is very good. However, one thing is that the dry eyes of people who use computers a lot last longer after the surgery, which will be relieved after using artificial tears. You can look at the computer after surgery, but not excessively. Just relax often and take your eyes off the computer intentionally. Does LASIK surgery require an incision? Does it hurt? LASIK is performed on the cornea, which is devoid of blood vessels and has rich nerve endings on the surface. The nerve endings on the surface of the cornea can be completely anesthetized by surface anesthetic drops. Will my vision rebound after laser surgery? Once your vision has stabilized (between one week and three months, depending on the individual), the results of the procedure will be long-lasting with little to no regression. However, due to the need for employment and education, a small number of patients who come in for surgery before their refractive status is fully stabilized may develop myopia in the future. Will I get premature presbyopia after surgery? Presbyopia is a physiological phenomenon of human aging, and corrective myopia surgery will not affect or change the degree and progress of presbyopia in any way. When myopic patients reach the age of presbyopia, most of them need to wear two pairs of glasses, one for distance viewing and the other for near viewing, which makes life and work more inconvenient. Do I need to be hospitalized after LASIK? No. You can go home the same day and do not need to be hospitalized. However, you may experience tearing and foreign body sensation for a few hours after surgery, and you should rest with your eyes closed. What time can I start working after surgery? After LASIK, there is no need for bandages and you can regain your vision in a few hours. You can live and use your eyes normally the next day, but you must pay attention to the scientific use of your eyes. It takes 5-6 months for the corneal tissue to fully heal and 1-3 months for the vision to stabilize after surgery. How long does LASIK treatment take? It takes about 10 minutes for both eyes, and the laser treatment takes only a few seconds to a few tens of seconds.
