Pigmentary Glaucoma, Primary Open Angle Glaucoma, Pseudoexfoliative Glaucoma
Conditions
Brief summary
The study objective is to demonstrate the safety of Minimally Invasive Micro Sclerostomy (MIMS) device for lowering elevated IOP in patients diagnosed with glaucoma.
Interventions
PROCEDUREMinimally Invasive Micro Sclerostomy
Creation of a drainage channel of 50 - 100 microns (diameter) at the sclera-corneal junction and extending from the anterior chamber to the interface between the sclera and the conjunctiva (subconjuctival space).

Inclusion criteria
* End Stage primary open-angle glaucoma, pseudoexfoliation glaucoma or pigmentary glaucoma in the study eye (EGS criteria) * Optic nerve appearance characteristic of glaucoma in the study eye * Best-corrected visual acuity (BCVA) of counting-fingers, hand movements, light perception or no light perception due to glaucomatous loss of central vision in the study eye * Patient is treated with 1 to 5 hypotensive medications in the study eye * Unsatisfactory medicated IOP (≥ 18 mmHg) at the screening visit in the study eye * Shaffer grade ≥ III in all four angle quadrants in the study eye * Subject is able and willing to attend all scheduled follow-up exams * Subject understands and signs the informed consent
Exclusion criteria
* Subjects presenting 1 or more of the following criteria will not be enrolled in the trial: * Ocular conditions with a poorer prognosis in the fellow eye than in the study eye * Closed angle forms of glaucoma in either eye * Congenital or developmental glaucoma in either eye * Other secondary glaucoma (such as neovascular, uveitic, lens-induced, trauma-induced, or glaucoma associated with increased episcleral venous pressure) in the study eye * Peripheral anterior synechiae (PAS), rubeosis or other angle abnormalities in the study eye * Subject has history of penetrating keratoplasty (PKP) * Any previous surgery in the study eye (except for clear corneal cataract surgery) where the conjunctiva is not intact and elastic. * Any ocular disease or history in study eye such as severe dry eye, active proliferative retinopathy, ICE syndrome, epithelial or fibrous down growth, and ocular pathology that may interfere with accurate IOP measurements * Prior surgery for an ab-interno or ab-externo device implanted in or through the Schlemm's canal in the study eye. * Use of oral hypotensive medication for glaucoma for treatment of the fellow eye * Less than the minimum visual function required for driving in the fellow eye: best-corrected visual acuity worse than 20/40 (Snellen equivalent) or Esterman visual field score less than 85%. * History of idiopathic or autoimmune uveitis in either eye * Severe trauma in study eye * active iris neovascularization, previous cyclodestructive procedure, prior scleral buckling procedure, presence of silicone oil, need for glaucoma surgery combined with other ocular procedures or anticipated need for additional ocular surgery in study eye within 12 month period * Vitreous present in anterior chamber, prior vitrectomy or virteous hemorrhage in study eye * Aphakia * Prior vitreoretinal surgery in study eye * Clinically significant ocular inflammation or infection within 90 days prior to screening * Unable to discontinue use of blood thinners in accordance with surgeon's standard preoperative instructions * Uncontrolled systemic disease that in the opinion of the investigator would put the subject's health at risk and/or prevent the subject from completing all study visits * Current participation or participation in another investigational drug or device clinical trial within the last 30 days before screening visit * Pregnant or lactating women
