Phototherapeutic keratectomy (PTK) uses the excimer laser to treat diseased corneal tissue. The photoablation of corneal opacities and irregular corneal surfaces promotes improvement in best corrected visual acuity and decreased frequency of recurrent erosion episodes. PTK is successful in a variety of corneal disorders and has less complications and a shorter recovery period than lamellar or penetrating keratoplasty.
