Therapeutic Procedures

PTK procedureThe excimer laser may provide a novel modality in the treatment of a number of superficial corneal disorders. This treatment is known as a phototherapeutic keratectomy or PTK.

Whether PTK eye surgery is used alone or as an adjunctive strategy in traditional corneal surgical techniques, a number of disorders affecting the corneal surface may be successfully treated by taking advantage of the excimer laser’s ability to meticulously remove superficial corneal tissue.

These include a variety of corneal degenerations and dystrophies, corneal irregularities, and superficial scars. While some of these conditions, heretofore, could be treated by mechanical superficial keratectomy techniques, PTK may minimize tissue removal and surgical trauma.

The smoother stromal surface achieved by the excimer laser procedure may improve the surface smoothness of the cornea, improve postoperative corneal clarity and decrease postoperative scarring, and facilitate subsequent epithelial adhesion.

Moreover, superficial corneal disorders which, in some cases, would otherwise require a cornea transplant may be amenable to treatment with the PTK procedure.

Thank you so much Doc! When I first came to you I was 20/50 now I'm 20/10. I'm ready to have a great year!

Dr. Hersh and his staff were excellent. I was comfortable from the time I walked in until the time I left after the procedure.
