About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Subjects of the ARGOS-01 and ARGOS-02 study with an implanted ARGOS-IO pressure sensor.

Exclusion criteria

  • N/A

Treatment and study plan

ARGOS-IO Sensor Pressure System

Device

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

Other names: EYEMATE-IO

Primary outcomes

  1. Safety: Number of Patients Experiencing a Device Related Serious Adverse Events (SADE) and Device Related Adverse Events (ADE)

    Time frame: Baseline visit to Day 1080 (V01 [Baseline visit] to V07)

    Number of patients experiencing a device related SAE (SADE) and device related complications (ADE) over the 36-months' clinical follow-up time.

  2. Performance: Level of Agreement Between GAT and the ARGOS-IO System

    Time frame: Baseline visit to Day 1080 (V01 [Baseline visit] to V07)

    Level of Agreement between intraocular pressure (IOP) measurements made using GAT & the ARGOS-IO system (IOP in mmHg) following the Bland-Altman method.

  3. Performance: Device Malfunctions

    Time frame: Baseline visit to Day 1080 (V01 [Baseline visit] to V07)

    Incidence, nature and seriousness of observed device malfunctions / deficiencies (DDs)

Secondary outcomes

  1. Patient's Compliance in IOP Self-monitoring (Daily Self-measurements)

    Time frame: Baseline visit to Day 1080 (V01 [Baseline visit] to V07)

    The patients' compliance in IOP self-monitoring throughout the clinical follow-up study. Daily self-measurements with the ARGOS-IO sensor were to be done at least 4 times daily (morning, noon, afternoon, evening).

  2. Patient's Compliance in IOP Self-monitoring (Self-measurement Sequences / Day)

    Time frame: Baseline visit to Day 1080 (V01 [Baseline visit] to V07)

    The patients' compliance in IOP self-monitoring throughout the clinical follow-up study. Daily self-measurements with the ARGOS-IO sensor were to be done at least 4 times daily (morning, noon, afternoon, evening).
