There are several types of laser surgery for myopia.

With the development of science and technology, laser surgery for myopia is changing with each passing day. At present, it has already become a very mature surgical method. In the earliest times, laser surgery for myopia required to lift the corneal epithelium, cut the laser below, and then wash it after it was done, wash away the so-called blood, and then cover the corneal flap back. This was the surgical method of the past. With the development of science and technology, laser surgery for myopia was changing with each passing day. At present, it had already become a very mature surgical method. The earliest laser surgery for myopia required to lift the corneal epithelium and make a laser cut below. After that, it was washed away to wash away the so-called blood. Then, the corneal flap was covered back. This was the surgical method of the past. Currently, there was a more advanced and mature method, which was the femtosecond laser method. Femtosecond laser, it makes the part to be cut directly under the epithelial layer of the cornea through the femtosecond laser, that is, it can do the cutting without making a corneal flap. After the fine laser cutting, a small opening is made at the edge of the cornea, and the cut part is gently taken out. Therefore, such a surgical method, the so-called patient becomes, first, less irritating; second, less error; and third, the visual effect is particularly good. This is the development of science and technology to bring advanced achievements, is also a very mature technology.
