- Values are means ± SD (standard deviation).
-
n sample size, BCVA best corrected visual acuity, logMAR log of the minimum angle of resolution.
-
† versus baseline; ‡ phacotrabeculectomy versus phacocanaloplasty.
- * Two patients developed filtering blebs after canaloplasty and were therefore excluded.
-
+ Two patients needed cyclodestruction to reach target IOP and were therefore excluded.
-
~ One patient underwent cyclophotocoagulation to lower IOP and was therefore excluded.
-
a Mann–Whitney U-test for independent samples without normal distribution.
-
b Wilcoxon signed-rank test for dependent samples without normal distribution.
