Primary Outcome Measures:
  • Efficacy [ Time Frame: 24 months ]

Enrollment: 47
Study Start Date: February 2005
Estimated Study Completion Date: May 2013
Estimated Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1 Device: Glaucoma Surgery
Comparing the effect in reducing IOP with two Trabecular Bypass Microstents Versus none in patients undergoing cataract surgery, with early open angle glaucoma or ocular hypertension.
Other Name: two Glaukos iStent Trabecular Bypass Microstents
Placebo Comparator: 2 Procedure: cataract surgery only
Subjects will undergo routine cataract surgery only (no stent implant).
Other Name: Phacoemulsification

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.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Newly diagnosed with open-angle glaucoma (OAG) or Ocular Hypertension with subjects not yet taking any glaucoma medications or recently diagnosed with mild open-angle glaucoma and are currently being treated with up to 2 glaucoma medications.
  • All subjects must need cataract surgery.

Exclusion Criteria:

  • Angle closure glaucoma
  • Secondary glaucomas except pseudoexfoliative and pigmentary; no neovascular, uveitic or angle recession glaucoma
  • Prior glaucoma procedures (eg trabeculectomy, viscocanalostomy, ALT, SLT, shunt implant, collagen implant, cyclo destructive procedures etc)
