Dr. Daniel Durrie is working on an alternative to eliminate the post lasik complications. Millions of Americans who have undergone Lasik surgery face a return to eyeglasses or contacts as their near vision — like everyone else's — begins to diminish with age.
Refractec Inc. of Irvine, Calif., has chosen Durrie Vision of Overland Park and four other ophthalmic practices across the country to conduct expanded clinical trials for this procedure called Post-Lasik Near Vision CK.
CK (conductive keratoplasty) is a radio-wave treatment that already has received Food and Drug Administration approval for treatment of presbyopia, or age-related loss of near vision, and hyperopia, or farsightedness.
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 creates a constrictive band, increasing the overall curvature of the cornea to bring near vision back.
According to Durrie the procedure made the following differences in tasks involving near vision:
* Following the procedure, 95 percent of patients were able to read a computer screen, compared with 67 percent prior to the Near Vision CK treatment
* Twenty-nine percent of patients were able to read menus or golf scorecards without glasses, but more than 86 percent were able to after Near Vision CK.
During the expanded trials, about 150 more patients older than 45 who have had Lasik vision correction are expected to receive CK.
