  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.

  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

5. Study Description

Brief Summary
The purpose of this study is to evaluate both the safety and feasibility of the surgical implantation of the ARGOS-SC implant during non-penetrating glaucoma surgery and the safety and usability of the ARGOS-SC implant and system in the year following the implantation.
Detailed Description
This study is designed as a prospective, open-label, multicenter, single-arm clinical investigation. Subjects will be followed up at regular intervals for one year following implantation to collect safety and performance information. Enrollment will be halted at every serious adverse device event (SADE). The sensor device is intended to be permanently implanted suprachoroidal in the human eye during non-penetrating glaucoma surgery and is used in conjunction with the hand-held MESOGRAPH reading device to telemetrically measure the intraocular pressure (IOP) of the implanted eye. The sample size calculation was based on the study's dual purpose of establishing safety and comparability of IOP measurements with the ARGOS-SC system to those made with GAT and DCT. IOP measurements will be made with all devices at various time points, resulting in a within individual control for IOP variables. Based on these calculations (performance, safety) and considering possible drop-outs, the exploratory investigation will enroll 24 patients. The minimum number of measurements required to hold the performance claim is approx. 120. With multiple (>8) measurements with either method (ARGOS, GAT) per patient, a sufficient number of paired measurements (in total >>120 measurement pairs) will be available to show equivalence of the methods (primary objective).
