† 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.
