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

Figure 2

Percentage of apoptotic KC keratocytes 24 hours following CXL. The use of riboflavin or UVA-light illumination separately had no significant impact on the percentage of apoptotic keratocytes compared to controls (). Following CXL using 0.05% or 0.1% riboflavin, the percentage of apoptotic KC keratocytes was significantly increased ( and , resp.).
