NearVision CK® is performed using small probe, thinner than a strand of human hair, that releases radio frequency (RF) energy.  The probe is applied in a circular pattern on the outer cornea to shrink small areas of corneal tissue.  This circular shrinkage pattern creates a constrictive band, like the tightening of a belt, to increase the overall curvature of the cornea.  The use of RF energy is one of today's most advanced surgical techniques.  In addition to its use in NearVision CK, RF technology is being used in prostate cancer therapy, back surgery and even cardiovascular procedures.

NearVision CK significantly improved patients’ near vision in a 12-month clinical trial study where 98 percent of patients following their treatment were able to see magazine-and newspaper-sized print.  Additionally, 87 percent could see phonebook sized print (significantly smaller then news print), when using both eyes.  No serious, sight-threatening or unanticipated safety events were reported.
