Additional applications of corneal cross linking.

Corneal collagen cross-linking (CxL) is a prevalent surgical method for the management of keratoconus. However, literature suggests that, further to keratoconus, CxL has a beneficial impact on a series of corneal related diseases and states. This article attempts to provide a contemporary review for all additional applications of CxL. Specifically, it outlines the most recent studies that demonstrate the beneficial impact of CxL for iatrogenic ectasias, pellucid marginal degeneration, infectious keratitis, bullous keratitopathy, and for ulcerative keratitis. The outcome of this review indicates that CxL could serve as a primary or adjuvant therapeutic modality for all aforementioned corneal-related pathologic states.
