  1. Values are means ± SD (standard deviation).
  2. n sample size.
  3. versus baseline; phacotrabeculectomy versus phacocanaloplasty.
  4. * Two patients developed filtering blebs after canaloplasty and were therefore excluded.
  5. + Two patients needed cyclodestruction to reach target IOP and were therefore excluded.
  6. ~ One patient underwent cyclophotocoagulation to lower IOP and was therefore excluded.
  7. a Mann–Whitney U-test for independent samples without normal distribution.
  8. b Wilcoxon signed-rank test for dependent samples without normal distribution.
