Conductive Keratoplastly (CK) uses a low-energy, high frequency radio current and is applied directly to the periphery of the cornea with a metal tip that is controlled manually by the surgeon.  This technology changes the collagen of the cornea to make the central cornea steeper, correcting the vision for farsighted patients and patients who need reading glasses only.

The procedure is approved by the FDA for patients with Presbyopia and who have a difficult time functioning without their reading glasses.  It is also approved for patients with low levels of farsightedness.  The best candidates for CK are patients over 40 years of age with between +0.75 and +2.50 diopters of correction and less than .75 diopters of astigmatism.

The treatment takes only a few minutes and is done by an ophthalmologist with only topical anesthetic.


  • Mild postoperative discomfort
  • Excellent safety profile
  • Minimal risk in re-treatments


  • Fluctuating vision for a few weeks after the procedure
  • Results are not permanent. The effect typically lasts one to three years.
  • Limited to patients with mild farsightedness, less than + 2.50 diopters and have less than +0.75 diopters of astigmatism
