 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 Utest for independent samples without normal distribution.

^{b} Wilcoxon signedrank test for dependent samples without normal distribution.
