The effect of the combination of lutein, curcumin and vit D (LCD) on the corneal epithelial thickness and corneal thickness in benzalkonium chloride (BAC)-induced dry eye disease in rats (n = 7 per group). Control: No treatment; Dry Eye: BAC-induced dry eye syndrome; LCD I; Dry Eye + LCD I: BAC-induced dry eye syndrome plus LCD I (100 mg/kg body weight); Dry Eye + LCD II: BAC-induced dry eye syndrome plus LCD II (200 mg/kg body weight). Data are presented as a scatter plot with means and standard deviations. (ANOVA and Tukey’s post-hoc test. Statistical significance between groups is shown by: ** p < 0.01; **** p < 0.0001 compared as control group; # p < 0.05; #### p < 0.0001 compared as Dry Eye group; $ p < 0.05 compared as Dry Eye + LCD I group).
