  1. Values are means ± SD (standard deviation).
  2. n sample size, IOP intraocular pressure.
  3. during follow-up; 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 Student´s t-test for independent samples with normal distribution.
  8. b one-way repeated measures ANOVA.
