CK For Astigmatism
Brian S. Boxer Wachler, MD

The 8-minute CK procedure is done in our office. Immediately following the procedure a corneal map is typically taken to assess the level of improvement. If there can be further improvement, additional CK spots are then simply added. Another corneal mapping is performed to confirm that 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 Intacs alone. Intacs and CK are routinely performed on the same day.

The figures above show over 8 diopters of astigmatism correction before (left) and after CK combined with Intacs was performed (right) in one patient.

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. HOWEVER, that is the reason it's crucial that CK is combined with Holcomb C3-R (or performed after it) to reduce CK regression and boost long term results.

The figures above show another patient who experienced over 4 diopters of astigmatism reduction before (left) and after CK with Intacs (right).

CK was originally developed for farsightedness and presbyopia, which involved using the probe to create a symmetrical circular pattern to change to the cornea. Our insights into keratoconus has 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 improvements in vision.
