Fig. 2: Kaplan–Meier survival analysis corresponding to failure criteria 2 for the phacoemulsification, endoscopic cyclophotocoagulation, and dual blade ab interno trabeculectomy (PEcK) and the phacoemulsification, endoscopic cyclophotocoagulation, and trabecular micro-bypass stent (ICE-1) groups.

There is no statistically significant difference between the survival functions (log-rank test, p = 0.41).
