Patient: I am now 37 years old and I have been wearing glasses for more than 10 years, both left and right sides are around 350, but I want to remove my glasses, but I don’t know if I can slowly recover them. (Some people say that if I don’t bring them, my vision will decrease even more, is that right?) Can an engineer please give me some knowledge and advice about this? How does myopia surgery work? Is it safe? Mou Zhangbing, Ophthalmology Department, Chengdu 363 Hospital: Hello! Myopia has the possibility of forming refractive amblyopia if you don’t wear glasses for a long time, which will lead to a decrease in corrected vision; it will not be because you don’t wear glasses, your vision will slowly recover. Excimer laser keratomileusis is the only means to remove glasses. The principle is to use an excimer laser to concave the center of the cornea, which is equivalent to grinding a contact lens on the cornea. The procedure has been performed for more than 20 years and has achieved good results in terms of surgical safety and results. However, a detailed preoperative examination is required to determine whether the surgery can be performed, and the surgery will be considered only after every indicator is met.
