Conductive Keratoplasty: An FAQ

FREE EVAULATION - Contact Diana for more information.

What is near vision conductive keratoplasty (CK)?
CK uses radio waves, instead of a laser to reshape the cornea to improve near vision. After the procedure, most patients can see well enough to read a menu, see the phone book, do their mail and do other near vision tasks without glasses. In fact, in the FDA study, 98% of patients could read newspaper-sized print after CK.

Who are candidates for CK?
Candidates are those people over 45 who have had good vision all of their life and now only need reading glasses. The best candidates are those who hate their reading glasses!

How is the procedure performed?
The procedure takes 3-5 minutes and is done in our office. A probe, thinner than a human hair touches a circular pattern around the periphery of the cornea and delivers low-dose radiofrequency energy. This shrinks the collagen which acts like a belt around the cornea, to steepen the center. Generally, it is only necessary to do only one eye.

Does it hurt?
The procedure itself is painless. The eye is a bit scratchy, with a foreign body sensation for a day or two afterwards.

When does the near vision improve?
Many people notice improvement right after the procedure, while some take a few days to a couple of weeks. The vision will fluctuate slightly, stabilizing within weeks.

Does the procedure last?
There is some very mild regression over the first 2 years and then it seems to stabilize. Studies done four years after the procedure do show stability but we are not sure just how long the effects of CK last. People will continue to age, however; even if the effect of the procedure lasts, it is assumed that, 5 to 10 years afterwards, something else may be done.

What are the complications?
The beauty of CK is that it is quite safe, with very few complications. Induced astigmatism is possible which would be treated by further CK. Infection and corneal erosions can also occur.
