Nowadays, more and more people think that wearing glasses is inconvenient; wearing contact is too troublesome, so it is better to do myopia surgery, however, little is known about the choice of myopia surgery, so here is a rough introduction about myopia surgery. Myopia surgery can be divided into two categories: corneal surgery and intraocular refractive surgery. Corneal surgery is performed on the surface of the eye, without opening the eye. This type of surgery has been performed worldwide for about 16 years and is relatively safe. Currently, more than 98% of the people who have their vision surgically corrected are having corneal surgery. Corneal surgery can be divided into two types: one is superficial, the full name is excimer laser corneal epithelial resurfacing. It is suitable for low to moderate myopia below 800 degrees, especially for people with five or six degrees of myopia and non-scarring body, and the results of this surgery are very good. The other type is stromal, known as excimer laser in situ keratomileusis, which has a faster recovery and is suitable for all people, and is currently the procedure of choice for most people. For people with higher degrees and corneas that are too thin, there is another option, which is intraocular refractive surgery. Intraocular refractive surgery involves opening the eye and moving the “lens” from outside the eye to inside the eye. In terms of safety, it is not as safe as corneal surgery because it has only been introduced in the last year or two. Safety: Safety is the first question many patients ask when they want to have surgery. As things stand now, this issue does not need to be questioned. Even if someone experiences dry eyes, redness and swelling of the eyes after surgery, it is temporary and can be reduced with time. Results: Many people ask, “Doctor, can my eyes reach 1.5 after surgery? In fact, the quality of vision we are talking about nowadays does not simply mean good farsightedness. For example, many people who work at a desk, although they have good farsightedness, have poor near vision and are uncomfortable with their eyes as usual. Therefore, the purpose of myopia surgery is to ensure eye comfort, balance between left and right eye vision, and balance between daytime and nighttime vision, rather than just pursuing farsightedness.
