Definition of Phototherapeutic Keratectomy
Phototherapeutic Keratectomy (PTK) – treatment with an excimer (cool) laser to smooth irregularities and dissipate cloudiness in the cornea. PTK is an ambulatory surgery procedure, with local anesthetic to numb the surface of the eye and a mild sedative for comfort. The procedure takes 20 to 45 minutes, depending on the extent of corneal sculpting needed.
