Statistically significant p<0.05 is shown in bold.
*Comparison of IOP and ACD/CAD at FFU with that prior to operation using Student’s paired t-test. Comparison of drugs at FFU with that prior to operation using Mann-Whitney test.
†Comparison of IOP and ACD/CAD among patients with three types of UBM configurations using analysis of variance. Comparison of preoperative drugs and drugs at FFU among patients with three types of UBM configurations using Kruskal-Wallis test. a. type Ⅰ versus type Ⅱ; b. type Ⅰ versus type Ⅲ; c. type Ⅱ versus type Ⅲ.
ACD, anterior chamber depth; CAD, corneal endothelium–anterior surface of the iris or CFPM distance; FFU, final follow-up; IOP, intraocular pressure; UBM, ultrasound biomicroscopy.
