Fig. (3) Number of lens epithelial cells after exposure to ultraviolet light. The cell number decreased after UV exposure in a dose-dependent manner (A). After UV exposure of 100 and 200 mJ/cm2, pre-treatment of carteolol hydrochloride had no significant effect on the cell number (B and C). In contrast, pre-treatment of carteolol hydrochloride at 10^-3M significantly inhibited the intracellular fluorescence after UV exposure to 400 mJ/cm² (D).
