Title: A Study of the Glaukos Trabecular Micro-Bypass Stent in Combination With Cataract Surgery in Open Angle Glaucoma Subjects.
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 open-angle glaucoma or ocular hypertension and co-existing cataract.


Options:
A: Inclusion Criteria:

* a previous diagnosis of POAG
* an IOP of \> 18 mm Hg at three separate visits if on one medication, or subjects on at least two medications with uncontrolled IOP on three separate visits.
* all patients were deemed likely to follow surgeon instructions and were able to give informed consent.

Exclusion Criteria:

* any glaucoma diagnosis other than POAG
* the presence of peripheral anterior synechiae (PAS)
* a cloudy cornea likely to inhibit gonioscopic view of the angle
* any previous ocular surgery
* history of trauma or ocular surface disease
* the presence of peripheral anterior synechiae (PAS)
* a cloudy cornea likely to inhibit gonioscopic view of the angle
B: Inclusion Criteria:

* Diagnosed with open-angle glaucoma (OAG) in the study eye. Pseudoexfoliative and pigmentary glaucoma are also acceptable diagnoses.
* Subject on at least one glaucoma medication
* Able and willing to attend follow up visits for two years post operative
* Able and willing to sign informed consent

Exclusion Criteria:

* Prior glaucoma procedures (eg trabeculectomy, viscocanalostomy, ALT, SLT, shunt implant, collagen implant, cyclo destructive procedures etc)
* Angle closure glaucoma
* Fellow eye already enrolled
C: Inclusion Criteria:

* Age 18 to 85 years
* Intraocular pressure greater than or equal to 18 mm Hg and less than or equal to 40 mm Hg
* Previous trabeculectomy, cataract extraction with intraocular lens implantation, or both

Exclusion Criteria:

* Unwilling or unable to give consent, unwilling to accept randomization, or unable to return for scheduled protocol visits
* Pregnant or nursing women
* No light perception vision
* Active iris neovascularization or active proliferative retinopathy
* Iridocorneal endothelial syndrome
* Epithelial or fibrous downgrowth
* Aphakia
* Vitreous in the anterior chamber for which a vitrectomy is anticipated
* Chronic or recurrent uveitis
* Severe posterior blepharitis
* Unwilling to discontinue contact lens use after surgery
* Previous cyclodestructive procedure, scleral buckling procedure, or presence of silicone oil
* Conjunctival scarring precluding a trabeculectomy superiorly
* Need for glaucoma surgery combined with other ocular procedures (eg cataract surgery, penetrating keratoplasty, or retinal surgery) or anticipated need for additional ocular surgery
D: 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)
* Fellow eye already enrolled
