NearVision CK® is a non-laser procedure that can reduce or eliminate farsightedness and presbyopia and offer those who have difficulty seeing small print the opportunity to read again without bifocals or reading glasses. It is best suited for patients over the age of 40 who had good vision until they reached their forties.
Near vision CK uses the controlled release of radiofrequency energy to reshape the cornea. A small probe is applied to the inner corneal tissue in a circular pattern, which causes it to shrink. This circular shrinkage pattern creates a constrictive band or belt-tightening effect, which steepens the curvature of the cornea and increases its focusing power.
Some people, who can see well at distance, elect to have “blended vision” and have only one eye treated to provide them with better near vision. NearVIsion CK may cause temporary swelling of the cornea so it may take a few days for the swelling to subside to appreciate the results.
The goal of CK is to turn back the clock and restore your vision to where it was when you were in your thirties and reduce or eliminate your need for reading glasses. How far the clock turns back depends on how your eye responds and how it heals. As your eyes continue to age, you may require additional treatments in the future. With CK, we are tightening collagen, and although the collagen “tightening” in the cornea lasts longer than the collagen tightening in the skin (facial wrinkles,) we know that collagen does tend to relax over time. The exact duration of CK results will vary in patients. Patients that have the CK procedure, may need additional CK treatment (or “upgrades”) anywhere from 2-3 years.
