What is CK?

NearVision CK is Changing People's Lives

Soon, you could be able to do these things without reading glasses:



CK Is Custom-Made For Baby Boomers

CK (Conductive Keratoplasty) is the only vision procedure designed specifically for Baby Boomers who want a safe, minimally invasive procedure to free them of reading glasses. CK has been performed for over seven years and more than 100,000 CK procedures have been done. There have been ZERO reported infections or major adverse affects with CK, so CK is extremely safe. The FDA first approved CK in 2002 for age-related farsightedness (hyperopia), a condition that differs from presbyopia in its effect on the eye's ability to focus, but has similar symptoms. The FDA approved CK for presbyopia in March 2004. Presbyopia, Greek for "aging eye," is a progressive condition that causes near vision to fade with age.

Many newspaper articles have featured Dr. Starr as he is the first and only ophthalmologist in the local area to perform CK. CK has become the fastest-growing refractive procedure since the introduction of LASIK. CK is the first and only non-invasive, FDA-approved refractive technology for improving the loss of near vision that accompanies presbyopia. A survey of Baby Boomers found that 2/3 of those surveyed would consider having an elective procedure to reduce their dependence on reading glasses. A full 42 percent ranked CK as their number-one choice, citing its non-invasive method and safety as the primary reasons for their preference. 


Instead of using a laser or scalpel, controlled radio waves gently change the shape of the cornea to improve vision, giving NearVision CK one of the highest safety profiles among all refractive eye procedures. More than 20 years of research into this technique have established the precise depth and temperature necessary to achieve refractive change.

How does it work?


Using a probe thinner than a strand of human hair, CK applies radio waves in a circular pattern on the outer cornea to shrink small areas of collagen. This shrinkage pattern creates a constrictive band (like the tightening of a belt), increasing the overall curvature of the cornea to bring near-vision back into focus for Baby Boomers.

Radiofrequency energy is one of today's most advanced surgical technologies. In addition to its use in CK, RF technology is being used in prostate cancer therapy, back surgery, even cardiovascular procedures.

NearVision is typically performed on just one eye, restoring near vision without compromising the patient's binocular distance vision. Healing time is rapid with most patients returning to work the following day.
