Photorefractive keratectomy (PRK), along with the related laser-assisted sub-epithelial keratectomy (LASEK), is a laser eye surgery procedure intended to correct a person's vision and reduce dependency on glasses or contact lenses. It permanently changes the shape of the anterior central cornea using an excimer laser to ablate a small amount of tissue from the corneal stroma, just under the corneal epithelium, whose outer layer is removed before the ablation.
