A Real-World Evidence Study of Goniotomy With the C-REX™ Instrument in Patients With Primary Open Angle Glaucoma

This real-world study collects data on patients with primary open-angle glaucoma (POAG) — the most common type of glaucoma — who have undergone a surgical procedure called goniotomy using a specific instrument called the C-Rex. The goal is to evaluate how well the procedure lowers eye pressure and preserves vision in everyday clinical settings. **You may be eligible if...** - You have been diagnosed with primary open-angle glaucoma (POAG) - You have had goniotomy surgery performed using the C-Rex instrument **You may NOT be eligible if...** - You had any other eye surgery within 8 weeks before your C-Rex procedure - Your eye pressure was higher than 33 mmHg before surgery - You have a type of glaucoma other than POAG - You have other significant eye conditions besides cataract or glaucoma Talk to your doctor to see if this trial is right for you.
