Abstract

The conductive keratoplasty is the application of low frequency radio waves to ‘shrink’ collagen fibrils within the cornea. As the collagen shrinks, the band constricts and there is a steepening of the corneal curvature central to the band. The amount of corneal steepening is controlled by treatment placement, intensity and duration. The advantages of CK over laser reshaping of the central cornea are it preserves the optical clarity of the visual axis and does not involve any tissue removal. It is also used to correct low to moderate levels of hyperopia and astigmatism in ammetropes as well as eyes made ammetropic due to LASIK or cataract surgery. The drawbacks include the initial myopic shift after treatment and the lack of consensus as to the long-term stability of the results. The chapter discusses about the histology, treatment, patient selection, predictability, stability, result and complications of CK.
