Viability, Apoptosis, Proliferation, Activation, and Cytokine Secretion of Human Keratoconus Keratocytes after Cross-Linking

Figure 1

Viability of human KC keratocytes 24 hours following CXL. Application of 0.05% or 0.1% riboflavin-5-phosphate solution without illumination or the UVA-light illumination alone did not show a significant impact on keratocyte viability compared to controls (). Using 0.1% CXL, viability of KC keratocytes decreased significantly ().
