What this trial studies

This observational study enrolls adults diagnosed with primary open angle glaucoma (POAG) who have undergone goniotomy surgery using the C-Rex Instrument. Participants are consented before the surgery and are followed for 12 months postoperatively to collect data on intraocular pressure (IOP), the use of glaucoma medications, and any complications related to the device. The study aims to gather real-world evidence regarding the effectiveness and safety of this surgical approach in managing POAG.

Who should consider this trial

Good fit: Ideal candidates for this study are adults with a diagnosis of primary open angle glaucoma who are scheduled to undergo goniotomy surgery with the C-Rex Instrument.

Not a fit: Patients with a history of intraocular surgery within 8 weeks prior to the C-Rex surgery or those with preoperative IOP higher than 33 mmHg may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the effectiveness of goniotomy surgery in lowering IOP for patients with primary open angle glaucoma.

How similar studies have performed: Other studies have shown success with similar surgical approaches for managing glaucoma, indicating potential for positive outcomes in this study.
