NearVision CK applies radio waves in a circular pattern on the outer cornea to shrink small areas of collagen. This shrinking 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. When the cornea is compressed, it causes a mechanical stretching effect on the corneal fibers that resists the natural tendency of the tissue being drawn toward the pulse of RF energy. Using the LightTouch technique, the amount of compression is greatly reduced or eliminated. In preliminary findings, this low-compression technique may produce more robust results by minimizing the corneal stretching associated with the standard CK technique.
