Conductive Keratoplasty (CK) is a non-laser vision correction procedure that uses radio waves to help restore near vision for patients with presbyopia. CK was designed for farsighted individuals (hyperopes) over the age of 40 who would like an alternative to wearing reading glasses. CK is not intended for nearsighted (myopic) patients.
CK eye surgery uses the controlled release of radiofrequency (RF) energy to heat and shrink corneal tissue. This treatment steepens the cornea; thereby allowing light to properly focus on the retina. The RF energy is applied to the eye in a circular pattern; avoiding the pupil entirely.
The procedure itself involves first numbing the eye with drops. A treatment pattern is then imprinted with rinse-away dye. Finally, a Keratoplast tip is used to apply the RF energy. As with other vision correction procedures, mild discomfort and light sensitivity may be experienced for a few days.
Due to certain drawbacks of the CK procedure, LASIK MD surgeons have decided not to perform it at their clinics.
