CK for Astigmatism

The 10-minute CK procedure is done in our San Leandro Horizon office. Immediately following the procedure a corneal map is typically taken to asses the level of improvement. If there can be further improvement, additional CK spots are then simply added. Another corneal mapping is performed to confirm tat the proper endpoint has been attained. CK is often combined with Intacs, since CK can provide further improvements to eyesight and supplement the improvement of Itacs alone. Intacs and CK are routinely perfomed on the same day.

CK works by using radiofrequency (non-laser) energy that is strategically delivered to the cornea by a small probe. A tiny probe applies heat to the outer cornea at the precise area where astigmatism reduction is needed. The heat causes a local tightening effect against the astigmatism, which can reduce the astigmatism and improve eyesight. Immediate improvement in the cornea shape is noted, as evidenced by the new corneal topography mapping. Potential risk of CK is regression of effect.

CK was originally developed for farsightedness and presbyopia, which involved using the probe to create a symetrical circular pattern to change the cornea. Our insights into Keratoconus have enabled us to understand the principles responsible for the irregular corneal shape that defines Keratoconus and how to improve it. CK has been a successful addition to reduce astigmatism and further improve the corneal shape. This has resulted in greater improvments in vision.
