Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Open-Angle Glaucoma Device: Glaucoma Surgery Procedure: cataract surgery only Not Applicable

Detailed Description:
The study will compare the reduction in IOP of those subjects implanted with two Glaukos micro-stents with the reduction in IOP for patients receiving only primary medical therapy (Xalatan - Latanoprost) or cataract surgery alone. Both groups will undergo routine cataract surgery.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 47 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
