WebRecently, we have developed collagen crosslinking induced by combined riboflavin/UVA treatment, thus increasing the biomechanical rigidity of the cornea to treat progressive keratoconus. The present safety study was performed to evaluate possible cytotoxic effects of combined riboflavin/UVA treatment on the corneal endothelium in vitro. Endothelial Web21 nov. 2024 · The Dresden protocol specified that for CXL to be performed safely, corneas should have a minimum corneal thickness of 400 µm after epithelial debridement.
Webthe progression of keratoconus and post–laser-assisted in situ keratomileusis (LASIK) corneal ectasia. Riboflavin serves as a photosensitizer. When it is activated by UVA radiation, oxygen radicals are released into the corneal stroma, followed by formation of new covalent bonds between collagen fibrils, thereby stiffening the corneal stroma.1
