Refractive Surgery: Conductive Keratoplasty (CK)

CK (conductive keratoplasty) is a procedure for reshaping corneal tissue to help you see better without glasses or corrective lenses. This procedure uses a tiny probe to send radiofrequency energy into the cornea. This shrinks the outer portion of the cornea, making the central cornea steeper.

  • Eyedrops numb your eyes. A device is used to keep your eyes open.

  • The tip of a probe is inserted into the cornea. The treatment lasts a few minutes for each eye.
