Scatter plots of IOP reduction as a function of preoperative IOP at 3 years in the effectiveness^a OAG population (n = 174^b) (A) and patient subgroup with POAG (n = 123) (B). Each data point represents one eye. The grey line delineates IOP reduction (lower portion) from IOP increase (upper portion), relative to baseline IOP. Data points below the 20%, 30% and 40% IOP reduction lines achieved that level of IOP lowering or more. ^aAll effectiveness analyses included one eye per patient; in cases of bilateral implantation, only the first implanted eye was analysed. ^bThis analysis included all patients who had IOP data at baseline. ^cIndicates IOP reduction success, as defined in the protocol. IOP = intraocular pressure, OAG = open‐angle glaucoma; POAG = primary open‐angle glaucoma.
