4- Laser therapy
In the recent years, laser therapy is used extensively and successfully to treat myopia in adults. There are multiple techniques using laser therapy in treating myopia. From these techniques:
-
- LASIK: LASIK is laser in situ keratomileusis. It is a technique used to treat myopia. In this procedure, a thin flap is done on the outer surface of the cornea, then a thin layer of the cornea is removed, and the flap return to its place. This laser technique is preferable as it has rapid recovery and less patient discomfort and side effects. This technique may not be suitable for treating all degrees of myopia.
- LASEK:LASEK is laser assisted subepithelial keratectomy. In this procedure, a thin flap is made in the surface of cornea, then the laser tries to reshape the cornea and to decrease its curvature. After finishing, the epithelium is returned to its place.
- Photorefractive keratectomy (PRK): PRKis a technique that resembles LASIK technique, except that all the epithelium is excised completely, the epithelium heals and regrows.
