The anterior segment of the eyes on the 18th day after alkali burn under cobalt blue light and the curve and the 18th day’s histogram of the corneal epithelial injury rate. After corneal fluorescence staining was performed on the 18th day, we found that the stained area in the radiation-treated lens group was smaller than that in the other groups (A). The change curve of the corneal epithelial injury rate in each group is shown in figure (B), and the corneal epithelial injury rate of the radiation-treated UCMSC lens group was the lowest on the 18th day compared with that of the other groups (C) (P < 0.05). There were significant differences according to the statistical analysis results: (ns: no significance; *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001. The error bars in the chart represent the standard deviation.
