Title: A Randomized Study Comparing the Safety and Efficacy of the InnFocus MicroShunt® Glaucoma Drainage System to Standard Trabeculectomy In Subjects With Primary Open Angle Glaucoma
Brief Summary: Assess the safety and effectiveness of the InnFocus MicroShunt when used to lower intraocular pressure (IOP) in subjects with primary open angle glaucoma where the IOP is not controlled when using maximum tolerated glaucoma medications.


Options:
A: Inclusion Criteria:

* An operable age-related cataract
* A diagnosis of POAG treated with 1 to 4 hypotensive medications
* Medicated IOP ≤ 31 mmHg
* Diurnal IOP ≥ 22 mmHg and ≤ 34 mmHg

Exclusion Criteria:

* Congenital or developmental glaucoma
* Previous argon laser trabeculoplasty
* Ab-interno or ab-externo device implanted in or through Schlemm's Canal
* Use of oral hypotensive medication for glaucoma for treatment of fellow eye
B: Inclusion Criteria:

1. Age 40-85 years
2. Open angle glaucoma (including pseudo exfoliative glaucoma)
3. Open angles (≥ Shaffer grade II)
4. Inadequately controlled IOP requiring surgical intervention
5. Visually significant cataract
6. Willing to complete quality of life questionnaires
7. Capable of informed consent and available for at least 1 year follow-up

Exclusion Criteria:

1. Any form of angle closure glaucoma
2. Secondary open angle glaucomas
3. Absence of clear angle landmarks on gonioscopy
4. Other ocular disease that may affect assessments of visual acuity, visual field, or accurate tonometry
5. Previous angle surgery or filtering procedure
6. Steroid use within the preceding 3 months
7. Presence of significant co-morbidities
C: Inclusion Criteria: - POAG on maximum tolerated glaucoma meds - Medicated ≥15mmHg and ≤40mmHg - Exclusion Criteria: - Previous conjunctival incisional ophthalmic surgery - Anticipated need for additional ocular surgery during the study - Secondary glaucoma - Any condition that prevents the device implantation or trabeculectomy in the superior region of the study eye
D: 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

Answer: C
