Eligibility Criteria
Inclusion Criteria:

- Sufficiently controlled intraocular pressure (IOP)
- Study eye needs to be phakic

Exclusion Criteria:
- Any other type of glaucoma other than primary open-angle glaucoma as defined by inclusion criterion 3

- Intraocular surgical procedure(s) within 6 months prior to ARGOS-IO implantation or any surgical procedure such as refractive eye surgery in the study eye that can affect the assessment of IOP by Goldmann applanation tonometry
- History of eye tumor
- Ocular disease other than glaucoma that may affect assessment of visual acuity and/or IOP by Goldmann applanation tonometry (choroidal hemorrhage or detachment, lens subluxation, thyroid ophthalmopathy)
- Anterior chamber configuration that puts the subject at high risk to develop an angle closure glaucoma
- History of extensive keloid formation
- Severe dry eye syndrome
- Subjects who will need to undergo ancillary procedures in the study eye at the time of implantation or during the post-operative study period
- Any known intolerance or hypersensitivity to topical anesthetics, mydriatics, plaster or silicone (component of the device)
- Existence of other active medical eye implant and/or other active medical implants in the head/neck region
- Any contraindication for intraocular lens (IOL) implantation such as choroidal hemorrhage, concomitant severe eye disease, excessive vitreous loss, extremely shallow anterior chamber, microphthalmos, non-age-related cataract, posterior capsular rupture, severe corneal dystrophy, untraceable IOP, zonular separation, color vision deficiencies
- Severe generalized disease resulting in a life expectancy shorter than a year
- Any clinical evidence that the investigator feels would place the subject at increased risk with the placement of the device
- Currently pregnant or breastfeeding
- 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
- Patients who are not suitable for the study based on the surgeon's evaluation
- Patients unable or unwilling to understand or comply with required study procedures
- Patients with psychiatric disorders influencing their judgement or autonomy
- 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.

5. Study Description
Brief Summary
The purpose of this study is to evaluate the safety and performance of the ARGOS-IO system in patients with POAG and indicated cataract surgery.
Detailed Description
This prospective, open-label, multi center, single-arm clinical investigation will enroll 22 consecutive patients.
Enrollment will be temporarily halted in case a serious adverse device effect (SADE) occurs, and Data and Safety Monitoring Board (DSMB) meeting will be conducted as soon as possible. The DSMB will then recommend whether to further continue the study as planned, or whether enrollment shall be stopped. In order to provide a complete overview of the study to the DSMB, an interim analysis will be performed after half of the study population (11-14 subjects) is enrolled with a minimum follow-up of 1 month. A conclusion for safety will be made if in total no more than 2 of the total of 22 patients experience a SADE.
The primary aim of this study is to show "safety", which will be evaluated based on the percentage of subjects who experience a SADE (="non-safety"), as defined in the primary endpoints.
The study will be declared a success if the final non-safety event rate is less than 6% (type II error rate of 0.20). The calculation is based on a design optimizing the minimum expected sample size with parameters alpha=0.05, beta=0.20, p0=0.75, p1=0.94.
