Conductive keratoplasty

Conductive Keratoplasty (CK) is a refractive surgery procedure designed to correct mild to moderate hyperopia, or farsightedness. The procedure uses radiofrequency energy to reshape the cornea and bring near vision back into focus. CK is typically used for patients over age 40 who have difficulty seeing up close, a condition known as presbyopia.

Procedure

CK is performed using a small probe, thinner than a strand of human hair, that releases radiofrequency energy. The probe is applied in a circular pattern on the outer cornea to shrink small areas of corneal tissue. This circular shrinkage pattern creates a constrictive band (like the tightening of a belt), increasing the overall curvature of the cornea. The procedure is performed in-office with topical (eye drop) anesthesia. It is a minimally invasive and typically takes less than five minutes.

Benefits and Risks

The primary benefit of CK is the improvement of near vision. However, as with any surgical procedure, there are risks involved. These may include glare, halos, starbursts, and night vision problems. Some patients may also experience regression over time, with a return of some of their hyperopia.

Post-Procedure Care

After the procedure, patients may experience some discomfort in their eye. This can usually be relieved with over-the-counter pain medication. Most people are able to return to their normal activities the next day.
