Kaplan-Meier survival plot for cumulative probability of complete success. Success was defined as an intraocular pressure (IOP) of less than 18 mmHg without glaucoma medication (complete success). Censored data occurred if a patient completed the 12-month visit and maintained an IOP of less than 18 mmHg without glaucoma medication over 12 months. In the phacocanaloplasty group, the line starts below 1.0 because 2 patients developed a filtering bleb in the early postoperative period and were countered as a failure.
