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 WebThe patients were divided in 2 groups: the accelerated “epi-off” crosslinking group (9 mW/cm 2 for 10 minutes) (A-CXL) included 90 eyes from 90 patients, and the standard “epi-off” crosslinking (3 mW/cm 2 for 30 minutes) (S-CXL) group included 93 eyes from 93 patients. The patients were consecutively included in the study.
