A Study of the Trabecular Micro-bypass Stent in Combination With Cataract Surgery in Subjects With Newly Diagnosed Open Angle Glaucoma and Subjects Diagnosed With Ocular Hypertension

The purpose of this study is to evaluate the safety and efficacy of the iStent trabecular micro-bypass stent in reducing intraocular pressure (IOP) in subjects with newly diagnosed open-angle glaucoma and subjects diagnosed with Ocular hypertension.
