Photorefractive keratectomy is used to change what?

Photorefractive keratectomy reshapes the front surface of the cornea with a laser to change how light is refracted as it enters the eye. By altering the corneal curvature, the eye’s optical power adjusts so images focus more accurately on the retina, correcting refractive errors such as nearsightedness, farsightedness, or astigmatism. It does not affect intraocular pressure, replace the cornea, or remove a cataract, which are addressed by other procedures.
