After the age of 40 years, the capacity of the eye to focus on near objects starts decreasing and keeps decreasing with advancing age. Hence every 4-5 years after the age of 40 we have to go for a change of near vision glasses. A person who did not have any power till 40 ends up with a +3 number by the time he becomes 55 years. This condition is called PRESBYOPIA.
NearVision CK (Conductive Keratoplasty®) can change how the eye focuses light by reshaping the cornea to improve near vision. It uses a controlled release of radiofrequency (RF) energy to shrink corneal tissue, which steepens the cornea. This steepening creates a safe and predictable modification to the topographical (surface) curvature of the cornea for the temporary reduction of presbyopic and hyperopic symptoms.

Did you know?
Conductive Keratoplasty isn't the only use of radiofrequency (RF) energy in medicine. Doctors have been safely using this technology in surgery since the 1950s
