Conductive Keratoplasty, or CK, is an alternative to typical laser surgeries for people who are over forty
and have hyperopia, astigmatism, or presbyopia. Developed by Refractec, the process received FDA approval for reduction of
hyperopia and in March 2004 received first and FDA approval for vision technology that improves presbyopia.
Conductive Keratoplasty Process
Conductive Keratoplasty uses heat from radio frequency wave instead of a laser to shrink the collagen fibers in
order to steepen the cornea. After anesthetic drops have been applied and have taken affect, a probe with a special tip that
transfers radio frequencies is used to administer eight to thirty-two uniform treatment spots around the periphery area of the
cornea. In Refractec's NearVision CK, a foot pedal is used to transmit the radio frequency energy. The heat from the radio
frequency is designed to shrink the collagen of the area and cause the cornea to steepen to a very high degree. Less regression is
expected due to the uniform delivery of heat and deep shrinkage of collagen.
Conductive Keratoplasty Candidates
People are best suited for Conductive Keratoplasty if they are over 40, have healthy eyes, have had stable vision for
at least six months, and have hyperopia in the range from +0.75 to +3.00 diopters. There maybe other reasons why you could be a
good or bad candidate and its best to ask your eye care doctor.
