Customized Corneal Cross-linking Using Different UVA Beam Profiles

Corneal cross-linking (CXL) is a novel therapeutic method to stop or slow the progression of keratoconus.1 There is evidence that keratoconus is a localized biomechanical disorder of the cornea.2 Thus, addressing the local disorder instead of the entire cornea could possibly reduce the amount of ultraviolet-A (UVA) energy delivered to the stroma.3 Biomechanical modeling of CXL has shown that selective CXL of the affected zone of the keratoconic cornea instead of CXL of the central 8- to 9-mm diameter zone may result in greater topographic flattening.4,5 This approach is exciting because it
