网页2023年7月18日 · Photorefractive keratectomy (PRK) is a laser refractive procedure used to ablate the corneal stroma to correct refractive errors. Though not performed as often as laser in situ keratomileusis (LASIK), there are select situations in which PRK may be the preferred option.
PRK (Photorefractive Keratectomy): Surgery & Recovery
网页Photorefractive keratectomy (PRK) is a laser surgery procedure to correct your eyesight. The laser makes small changes to the shape of your cornea, the clear, protective layer at the front of your eye. Reshaping your cornea affects how it bends light, which changes how you see. PRK is a predecessor of laser-assisted in situ keratomileusis (LASIK).
