Using radiofrequency (RF) energy, conductive keratoplasty can change how the eye focuses light by reshaping the cornea to make it steeper. After a topical anesthetic (eye drops) has been applied, controlled RF energy is applied in a circular pattern to shrink the corneal tissue. This pattern is applied in the periphery of your cornea and therefore minimizes interference with your line of sight (i.e., pupil). A device called a “speculum” holds your eye open during the procedure.
Once finished, you don’t have to wear a patch and can usually return to work or normal activities the next day. Vision generally begins improving in about a week’s time. As with other procedures, the level of improved vision may be temporary. While CK can turn back the clock on your vision, it cannot stop the clock entirely.
CK can also help patients with farsightedness, or hyperopia, a condition in which the eye is too flat. CK modifies the topographical (surface) curvature, making it steeper and therefore improving vision.
