Performance and Safety of the ARGOS-SC Suprachoroidal Pressure Sensor in Patients With Glaucoma Undergoing Non-penetrating Glaucoma Surgery

Inclusion Criteria: 1. Subjects able to understand the informed consent and willing to participate as evidenced by providing informed consent. 2. Male or female aged ≥ 18 years on the day of screening Female subjects of childbearing potential (not surgically sterilized or more than one year post-menopausal) must be willing to use adequate contraception throughout the trial and must have a negative pregnancy test (urine beta-hCG) within 24 hours prior to ARGOS-SC pressure sensor implantation. 3. Diagnosis of open angle glaucoma requiring a non-penetrating glaucoma surgery (NPGS). The medical indication for a non-penetrating glaucoma surgery must be given irrespective of the study participation. Potential study patients will be solicited for participation in the clinical trial only after the patient has given consent to the non-penetrating glaucoma operation. 4. Subjects able and willing to attend all scheduled visits and comply with all study procedures Exclusion Criteria: 1. Contraindications for a non-penetrating glaucoma surgery * Neovascular glaucoma, primary and secondary angle closure glaucoma * Condition after previous glaucoma incisional surgery * IOP \> 40 mmHg 2. Myopia (\> -6 dpt) or hypermetropia (\> +4 dpt) 3. Axis length \< 22 mm or \> 26 mm 4. Exudative age-related macular degeneration, instable macular degeneration 30 days prior to inclusion, or macular edema 5. Acute retinal detachment 6. Uncontrolled Diabetes Mellitus (DM) with manifestation of moderate to severe non-proliferative diabetic Retinopathy (DR) or proliferative DR. 7. History or evidence of severe active inflammatory eye diseases (i.e. uveitis, retinitis, scleritis) in one or both eyes within 6 months prior to ARGOS-SC implantation 8. Ocular surgery procedure(s) (excluding selective laser trabeculoplasty and peripheral iridotomy) within 6 months (cataract surgery within 3 months) prior to ARGOS-SC implantation in the study eye that can affect the assessment of IOP by Goldmann Applanation tonometry 9. Ocular disease other than glaucoma that may affect assessment of visual acuity and/or IOP by Goldmann Applanation tonometry/Pascal Dynamic Contour Tonometry (e.g. choroidal hemorrhage or detachment, lens subluxation, thyroid ophthalmopathy) 10. Existence of other active medical eye implant and/or other active medical implants in the head/neck region 11. Difficulties or complications during NPGS procedure or implantation of ARGOS-SC sensor, as assessed by surgeon (e.g. perforation of trabeculo-descement's membrane; excessive aqueous filtration through TDM leading to shallow anterior chamber; excessive bleeding; choroidal detachment) 12. Severe generalized disease resulting in a life expectancy shorter than a year 13. Currently pregnant or breastfeeding 14. Participation in any study involving an investigational drug or device within the past 30 days or ongoing participation in a study with an investigational drug or device 15. Patients who are not suitable for the study based on the surgeon's evaluation 16. Patients unable or unwilling to understand or comply with required study procedures 17. Patients with psychiatric disorders influencing their judgement or autonomy 18. Subject and/or an immediate family member is an employee of the investigational site directly affiliated with this study, the sponsor or the contract research organization. 19. Enrollment of the fellow eye in this clinical study
