a A scatterplot revealed a statistically significant correlation between ACV change value (mm3) and ICL central vault (μm) (Pearson’s correlation coefficient r = 0.528, P < 0.001). Linear regression equation: y = 21.56 + 5.5*x. b Spearman’s correlation analysis revealed a positive and significant correlation between ACV change value (mm3) and preoperative ACD (mm) (r = 0.665, P < 0.001). Linear regression equation: y = 2.69 + 0.00686*x
