Kaplan-Meier plots of the cumulative probability of failure using the qualified success criteria. (≥20% IOP reduction and an IOP of less than 18 mmHg with or without medication and/or without any secondary intervention). The curve indicates that 76.1 and 72.1% of eyes with POAG (dotted line) and PXG (solid line) respectively achieved qualified success until 12 months postoperatively. The difference was statistically not significant (p = 0.626; LogRank)
