The CK procedure is indicated for the correction of farsightedness.
Farsightedness, or hyperopia, is a condition in which the eye is too flat. CK modifies the topographical curvature of the cornea, making it steeper. This steepening is what corrects the vision.

How the procedure is performed

CK uses a pen-shaped instrument with a cool tip as thin as a human hair. After application of a topical anesthetic (i.e., eye drops), your doctor will apply radio frequency (RF) energy in a circular pattern. This pattern is along the periphery of the cornea and therefore minimizes interference with your line of sight. A device called a "speculum" is inserted to hold your eye open during the procedure. It can be performed in a little as three minutes. CK is considered painless. Once finished, you don't have to wear a patch and can usually return to work the next day. Vision begins improving in about a week's time.

Advantages of this procedure are:

1.) Spares the visual axis
2.) Is a fast and painless procedure
3.)Involves no “cutting”
4.) Has faster healing and visual recovery than LTK
5.) Has far less regression over longer time periods than LTK
6.) May be used for astigmatism treatment
7.) May be repeated for “lost” effect

Disadvantages of this procedure are:

1.) Slower healing and visual recovery than Laser treatments
2.) Slightly longer treatment time than laser surgery
