CK (for "conductive keratoplasty") is a thermal procedure designed to reduce the need for reading glasses, and suited for those 40+ years of age with good distance vision. CK applies radio-frequency energy to the peripheral cornea in a circular pattern, to induce a relative flattening of corneal curvature peripherally, with steepening of curvature centrally. The steepened central curvature increases the focal power of the eye, allowing you to see near objects.

CK is performed in the office setting using anesthetic drops. Some patients may experience mild discomfort and light sensitivity for a few days after the procedure. Near vision is improved immediately, but may take about a month to stabilize.

One known characteristic of CK is that the effect may fade over time. While CK may be a treatment for presbyopia, it is not a cure. CK is not designed or intended to correct astigmatism.
