From: An in vitro investigation into the impact of corneal rinsing on riboflavin/UVA corneal cross-linking

Average time taken for complete digestion of untreated and cross-linked (CXL) corneas in Run 2. CXL treated corneas (Groups 3–6) showed enhanced resistance to enzymatic digestion compared to untreated corneas (P < 0.01 for Groups 3–5; P < 0.05 for group 6). CXL, corneal cross-linking; UVA, ultraviolet-A light; BSS, balanced salt solution
