Excimer laser refractive keratectomy

Excimer laser surgery is the use of excimer laser to perform a refractive cut of the substromal layer of the corneal flap, thereby reducing the corneal curvature of the pupil area to achieve the purpose of correcting myopia (commonly speaking, the cornea is treated as a transparent material, and Made a pair of lenses). Myopia can be corrected from 200 degrees to 2000 degrees. From the current clinical observation, this operation is a common operation to correct high myopia.
