1. Males or females, 18 years of age or older.
2. Diagnosis of primary or secondary open angle glaucoma during screening/baseline visit or earlier.
3. Grade 3 (open, 20-35 degrees) or grade 4 (wide open, 35-45 degrees) according to Shaffer Angle Grading System.
4. Glaucoma not adequately controlled by one to four different topical hypotensive medication(s), given each for at least one month, as confirmed by 21mmHg < IOP < 35 mmHg in the study eye at baseline visit.
5. Patients must be willing and able to return for scheduled study-related examinations.
6. Patients must provide written informed consent.
1. Grade 2 (narrow, 20 degrees), grade 1 (extremely narrow, less or equal to 10 degrees) and grade 0 (closed or slit) according to Shaffer Angle Grading System in the study eye.
2. Neovascular glaucoma in the study eye.
3. Corneal opacity or iridocorneal angle not visible through gonioprism in the study eye, preventing correct placement of the implant in the stud eye.
4. Prior glaucoma surgery in the study eye. Patient treated with argon laser trabeculoplasty or selective laser trabeculoplasty in the study eye are eligible if treatment was performed � 90 days before baseline visit in the study eye.
5. Visual field defect in the 10-degree central field in the study eye.
6. Any eye surgery that was performed � 90 days before baseline visit in the study eye.
7. Anticipated need for ocular surgery or retinal laser procedure in the study eye 12 months following surgery in the study eye.
8. Anterior chamber anatomic configuration of high risk for development of angle closure glaucoma in the study eye.
9. Pre-existing ocular or systemic pathology that, in the opinion of the physician, is likely to cause postoperative complications following implantation of the device in the study eye.
10. Clinically significant corneal disease (e.g., corneal dystrophy) in the study eye.
11. Evidence of crystalline lens subluxation or luxation in the study eye.
12. Evidence of vitreous loss in the anterior chamber in the study eye.
13. Clinically significant intra-ocular inflammation or infection, presence of ocular disease such as uveitis, ocular infection, severe dry eye, severe blepharitis, active proliferative/inflammatory retinopathy in the study eye.
14. Presence of silicone oil in the study eye.
15. Patients treated with systemic acetazolamide within 3 days before screening/baseline visit.
16. Patient with poor vision score: +1.0 in non-study eye, unless there is an expected benefit for the study eye in the opinion of the investigator.
17. Participation in any study involving an investigational drug or device within the past 3 months and planned participation to any other study during the present study.
18. Only for women of childbearing potential: positive blood pregnancy test at baseline visit.
19. Individuals under tutorship or trusteeship.
