Corneal Epithelial Removal with a Newly Designed Epithelial Brush

Table 1

Ratio of the epithelial defect area at each time point after epithelial removal to the epithelial defect area immediately after epithelial removal.

Statistically significant difference in the epithelial defect area between immediately after epithelial removal and at each time point. Kruskal–Wallis test. ^‡ value could not be obtained due to the complete healing of the epithelial defect in the Ocu and Amo groups.
