Glaucoma is the leading cause of irreversible blindness worldwide [Medical and surgical therapies for treating glaucoma focus on lowering intraocular pressure (IOP), currently the only known modifiable risk factor [In the surgical realm, phacoemulsification alone often is associated with modest IOP reduction due to an increase in outflow facility [The iStent Endoscopic cyclophotocoagulation reduces aqueous production, thereby decreasing the inflow component of the inflow/outflow balance that contributes to IOP [Both ECP and iStent The present prospective multicenter study compares 1 year outcomes following phacoemulsification + ECP (Group 1) or phacoemulsification + ECP + iStent
