Conductive Keratoplasty (CK)

Conductive keratoplasty, or CK, is a type of refractive surgery that uses mild heat from radio waves to shrink the glue-like connective tissue called collagen in the periphery of the cornea. This steepens the cornea, giving farsighted patients with presbyopia better near and distant vision while improving near vision for patients with presbyopia alone. With CK, some corneas have a tendency to revert to their original states, and vision correction fails to remain stable.
