General myopia surgery can be divided into the following categories:
1. laser optical keratectomy: the principle is to remove the epithelial layer on the corneal surface, and then vaporize the corneal tissue that the laser wants to remove. The surgical equipment and operation are relatively simple, and there are relatively few postoperative complications. The main complications are dry eye and night glare.
2. Excimer laser in-situ keratomileusis: Excimer laser surgery uses excimer laser to photorefractive cut the stroma layer under the corneal flap, thus reducing the corneal curvature in the pupil area and achieving the purpose of correcting myopia (generally speaking, the cornea is regarded as a transparent material and cut into a pair of lenses). Can correct myopia of 200-2000 degrees.
