This is a prospective, multi-center study that will examine subjects with documented mild to advanced primary open angle glaucoma (POAG), who may or may not have a cataract requiring removal and placement of an intraocular lens.
Study subjects will be grouped by the severity of their disease (either mild/moderate or advanced). If all inclusion and exclusion criteria are met subjects in all four groups will be implanted with the Hydrus Aqueous Implant. Subjects in whom a cataract is present will undergo standard cataract removal and IOL implantation concurrent with implantation of the Hydrus.
Postoperatively, subjects will undergo a complete ophthalmic evaluation at regularly scheduled intervals.
