(above) Representative image samples stained with Rose Bengal in each group performed on day 0 (immediately after povidone-iodine (PI) treatment) (a) control group (b) 1-min PI group (c) 3-min PI group (d) 10-min PI group. (below) Comparison of Rose Bengal staining scores among the four groups. The Rose Bengal staining scores differed significantly between the control and 3-min PI group, the 3-min and 10-min PI groups, and the 1-min and 10-min PI groups on day 0. Data show means ± standard deviations (error bars). Day 0 indicates the day immediately after PI instillation. * p < 0.05 (Steel–Dwass test for the differences among the four groups)
