How is laser surgery for treating myopia?

Laser treatment for myopia, commonly referred to as laser corneal refractive surgery, includes procedures such as laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK). These surgeries improve vision by reshaping the cornea, thereby reducing or eliminating the need for glasses or contact lenses. 1. **Surgical Procedure**: In LASIK, the surgeon creates a thin flap on the corneal surface, then uses a laser to precisely remove inner corneal tissue to adjust its curvature. In PRK, no corneal flap is created; instead, the laser acts directly on the corneal surface, which may result in a longer recovery period. 2. **Effectiveness and Safety**: Laser treatment for myopia has a high success rate, with most patients experiencing improved vision, often achieving 20/20 vision. However, not all patients achieve perfect results, and some may still require low-diopter glasses. Surgical risks include dry eyes, night glare, overcorrection, or undercorrection. These complications are relatively rare when the procedure is performed by experienced surgeons at qualified medical facilities. Note that laser treatment for myopia is an effective method of vision correction, but individual variations and potential risks should be carefully evaluated under the guidance of a physician.
