ACD, anterior chamber depth; AL, axial length; CCT, central corneal thickness; HCD, horizontal corneal diameter; IOP, intraocular pressure; mmHg, millimeters of mercury.
ANOVA was used for continuous variables. The Pearson's chi-squared test and the Fisher's exact test were used for the categoric variables.
a
Comparison between type II and type I.
b
Comparison between type III and type II.
c
Comparison between type III and type I.
P-values with statistical significance (<0.05) are highlighted in bold.
