Conductive Keratoplasty (CK)
Conductive Keratoplasty utilizes radio frequency energy to change the focusing power of the eye used to correct farsightedness (hyperopia and presbyopia). By directing the energy at the collagen tissue in the cornea in concentric circles, the process adds contour to the tissue so that the eye can focus on near objects. CK does not require an incision and no eye tissue is removed.
Depending on the type and severity of the cornea curvature, thermal spots are positioned in one or more ring formations just outside the line of sight of the eye. The surgeon does this by placing the tiny penetrating tip of the radio frequency generator into the cornea and applying the energy. The conductive qualities of the corneal tissue transfer the energy as heat, denaturing the collagen at the spot. The circular column of flattened corneal tissue that is formed is very small, approximately 100 microns wide and 500 microns deep. When created in ring formations this increases (steepens) the curvature of the cornea, enabling the eye to focus on near objects.
Recovery time: 2 to 3 days.
