Phototherapeutic Keratectomy (PTK)

The cornea is the outermost layer of the eye, and its function is to bend light rays so they focus directly on the retina. The cornea is normally clear and smooth, but when the surface of the cornea becomes rough or develops cloudy spots, light is not able to focus precisely on the retina and can result in blurry or inconsistent vision.

Some people’s vision is diminished, even with glasses or contacts, because of these irregularities in their cornea. Phototherapeutic Keratectomy (PTK) uses a laser to remove haziness and irregularities, restoring clearer sight for the patient.
