Primary Open-angle Glaucoma | Device: ARGOS-IO Sensor Pressure System | Not Applicable |
This study is a prospective open-label, multicenter study for clinical follow-up of the ARGOS-01 and ARGOS-02 patients.
From the ARGOS-01 to the ARGOS-02 study, some modifications were made to the form of the ARGOS-IO implant in consequence of the outcomes of the ARGOS-01 study.
Maximal 5 patients of the ARGOS-01 study and maximal 21 patients of the ARGOS-02 study will take part in this study.
The sensor was always implanted in one eye only which will be the study eye.

Single-arm longterm follow-up ARGOS-IO Sensor Pressure System
The ARGOS-IO sensor was already implanted in a previous study as ARGOS-01 or ARGOS-02.
|
Device: ARGOS-IO Sensor Pressure System
The ARGOS-IO Pressure sensor have been additionally implanted during local routine working procedures for cataract surgery in Patients with Primary Open Angle Glaucoma (POAG) and indicated cataract surgery in previous studies ARGOS-01 and ARGOS-02

- Safety measured by Incidence of medical-device related adverse events and serious adverse events [ Time Frame: 3 years ]The primary objective of this clinical trial is to evaluate the long-term safety and tolerability of the ARGOS-IO pressure sensor under consideration of incidence, nature, severity and seriousness of observed medical device related adverse and serious adverse events.An AE is considered to be device-related if there is at least a possible relationship to the medical device according to the rating of the investigator.
- Limits of agreement between IOP measurements made using GAT and the ARGOS-IO system at each study visit. [ Time Frame: 3 years ]IOP measured in mmHg
- Limits of agreement between IOP measurements made using DCT and the ARGOS-IO system at each study visit. [ Time Frame: 3 Years ]IOP measured in mmHg
- Incidence of observed device malfunctions and nature of device malfunction [ Time Frame: 3 years ]A device malfunction is e.g. difference of more than 5 mmHg between ARGOS-IO and GAT, readout error of the Mesograph because of measurements outside -2 and +70mmHG.
- Patient's compliance in IOP self-monitoring [ Time Frame: 3 years ]Daily self-measurements with the ARGOS-IO sensor should be done at least 4 times daily (morning, noon, afternoon, evening)
- Impact of IOP self-monitoring on glaucoma progression [ Time Frame: 3 years ]Visual field (db), cup/disc ratio, OCT of the optic nerve (µm) and the IOP (mmHg) has to be compared together to evaluate glaucoma progression
- Incidence in glaucoma medication change [ Time Frame: 3 years ]Number of glaucoma medication
- Number of unscheduled visits due to self-measured increased intraocular pressure [ Time Frame: 3 years ]The patients decide to come for a visit by their own due to any reason. This will be documented.
