PTK

In relatively rare circumstances, a person’s vision may become blurry or the eye may feel uncomfortable due to scar tissue on the cornea or an irregular corneal surface.

Phototherapeutic keratectomy (PTK) uses the Excimer Laser to remove only the scarred tissue or to smooth the corneal surface by focusing the laser beams only on the surface abnormality.

PTK is an outpatient procedure, generally performed under a topical anesthesia. Following treatment, a bandage contact lens is placed on the patient’s eye for comfort. Eye drops and topical ointment are used after the procedure to improve healing.

Following PTK, the patient may still not have perfect vision and may require glasses or contacts to achieve visual acuity.
