Kaplan–Meier survival plot of the cumulative probability of success for eyes without previous angle surgery (Group 1) and eyes with previous angle surgeries (Group 2) after microcatheter-assisted trabeculotomy for pediatric glaucoma over 12 months. Success was defined as an IOP <21 mm Hg with at least a 30% reduction from preoperative pressure levels with (qualified success) or without (complete success) the use of antiglaucoma medication. Eyes undergoing a secondary surgical procedure were classified as failures and censored from analysis subsequent to the intervention. The differences between groups were analyzed by the log-rank test.
