NCT ID NCT06615661
First seen Jul 21, 2026 · Last updated Jul 22, 2026 · Updated 1 time
Summary
This study follows 100 adults with primary open-angle glaucoma who had a goniotomy procedure using the C-Rex surgical instrument. The goal is to see how well the surgery lowers intraocular pressure and reduces the need for glaucoma medications over 12 months. Researchers will also track any device-related complications.

- C-Rex Instrument, a manual ophthalmic surgical device used for goniotomy
- What this could lead to
- If successful, this could confirm that the C-Rex device is a safe and effective surgical option for lowering eye pressure in glaucoma patients.
