What is Conductive Keratoplasty?

Conductive Keratoplasty (CK) can change how the eye focuses light by reshaping the cornea to treat farsightedness. It uses a controlled release of radio frequency (RF) energy to heat and shrink corneal tissue, which steepens the cornea. This steepening creates a safe and predictable modification to the cornea for the temporary reduction of farsightedness

How does CK work?

CK uses a pen-shaped instrument with a cool tip as thin as a human hair. After application of a topical anesthetic (i.e., eye drops), your doctor will apply radio frequency (RF) energy in a circular pattern.

This pattern is along the periphery of the cornea and therefore minimizes interference with your central vision. A device called a "speculum" is inserted to hold your eye open during the procedure.

Once finished, you don't have to wear a patch, and can usually return to work the next day. Vision slowly improves over the next several weeks.

Will the instrument used in the CK procedure penetrate the cornea?

The small, pen-shaped instrument used to apply radio frequency (RF) energy does penetrate, to a specific depth, in the cornea (approximately 0.45 mm or less than 1/50 of an inch).

The actual penetrating tip (KeratoplastT Tip) is as thin as a human hair. It also has a specially designed stop to eliminate the risk of penetrating the cornea too deeply.

What are the risks and side effects of CK?

Because CK is minimally invasive and well controlled, the procedure has very few surgical complications. As you can see from the diagram, the procedure does not touch the center of the cornea. During the first 24 to 48 hours after surgery, you may experience tearing and some discomfort, including a foreign-object sensation in the eye. The new reading vision will stabilize during the following weeks.
