Primary Outcome Measures:
  • Proportion of eyes with ≥ 20% decrease in intraocular pressure (IOP) from baseline to the hypotensive medication-free 24-month postoperative examination [ Time Frame: 24 months postoperative ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Mean change in IOP between baseline and hypotensive medication-free 24-month postoperative examination [ Time Frame: 24 months postoperative ] [ Designated as safety issue: No ]
  • Proportion of eyes with postoperative IOP ≥ 6 and ≤ 18 mmHg, as measured by Goldmann Tonometry, at the hypotensive medication-free 24-month postoperative examination [ Time Frame: 24 months postoperative ] [ Designated as safety issue: No ]

Enrollment: 897
Study Start Date: September 2009
Estimated Study Completion Date: March 2015
Estimated Primary Completion Date: March 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: CyPass Micro-Stent + Cataract Surgery
Subjects in the CyPass Micro-Stent + Cataract Surgery arm of the study will receive the CyPass Micro-Stent at the conclusion of their cataract surgery.
Device: CyPass Micro-Stent
The CyPass Micro-Stent is a small tube with a through-lumen designed to redirect aqueous fluid from the front to the back of the eye.
Active Comparator: Cataract Surgery
Subjects in the Cataract Surgery arm of the study will not receive the CyPass Micro-Stent at the conclusion of their cataract surgery.
Procedure: Cataract Surgery
Cataract Surgery involves the removal of the natural lens, which has become clouded (called a cataract), and insertion of an artificial lens (called an intraocular lens). This procedure is done through a small surgical incision in the eye.
