Laser treatment myopia, can you treat astigmatism

Laser can treat myopia and astigmatism.

Laser can not only treat myopia, but also astigmatism, such as excimer laser refractive ablation, laser-assisted subepithelial keratectomy, etc. Excimer laser refractive ablation is to remove corneal epithelium mechanically or laser, and then use excimer laser to cut a small amount of superficial corneal tissue, changing the curvature of the corneal surface, and finally achieving the purpose of correcting astigmatism; Laser-assisted subepithelial keratectomy (LASK) is a procedure to correct astigmatism by making an upper skin flap through the chemical action of alcohol on the basement membrane of corneal epithelial cells, then using excimer laser to change the curvature of cornea, and finally replacing the upper skin flap or removing the epithelial flap.
