Dr. Duffey performs Conductive Keratoplasty (CK) for presbyopic patients who desire a fast, convenient and comfortable in-office alternative to laser refractive surgery. CK utilizes radiofrequency (RF) energy applied to the outer aspects of the cornea to change the central corneal curvature. This is a no-laser, no-cutting procedure with an excellent margin of safety.

CK has been FDA-approved since 2002 and used worldwide for many more years. Healing time is rapid with most patients returning to work the following day. The FDA reports that the magnitude of correction with this treatment diminishes over time with some patients retaining some, or all, of their intended refractive correction. When done for presbyopia (the loss of reading vision after age 40), CK is typically done on the non-dominant eye. Therefore only one eye is required to have surgery for presbyopia, cutting the expense and risk of surgery in half.
