Aim. To report a case of 40-year-old male with progressive bilateral keratoconus who had undergone transepithelial phototherapeutic keratectomy (TE-PTK) and corneal collagen cross-linking (CXL) using hypoosmolar riboflavin solution in a same day procedure. Methods. Eye examination showed that UCDVA...

The reaction catalyzed by riboflavin synthase utilizes two identical 6,7-dimethyl-8-D-ribityllumazine substrate molecules. Three bis(6,7-dimethyl-8-D-ribityllumazines) were, therefore, synthesized in which the two lumazine moieties were connected through their N-3 nitrogen atoms by polymethylene linker chains containing three, four, and five...
