Clinical Study Evaluating the Efficacy and Safety of CID v2.2 in Glaucoma Surgery

This study is evaluating a small drainage device called CID v2.2, which is implanted in the eye to lower pressure in people with glaucoma. It is designed for patients whose eye pressure is not adequately controlled by 1 to 3 glaucoma eye drop medications and who need glaucoma surgery (without cataract surgery at the same time). **You may be eligible if...** - You are 18 or older with open-angle glaucoma (including pigmentary or pseudoexfoliative types) - Your eye pressure is not sufficiently controlled on 1 to 3 medications - Your eye pressure is between 18 and 30 mmHg (or 18–25 mmHg if on 3 medications) - Your visual field loss is mild to moderate (not worse than -15 dB) - Your corneal thickness is within a specific range (480–620 micrometers) - You are scheduled for glaucoma surgery alone (not combined with cataract surgery) **You may NOT be eligible if...** - You have a known allergy to the device materials or are a known steroid responder - You have had prior glaucoma surgery - You have certain types of glaucoma (such as angle-closure, neovascular, or uveitic glaucoma) - You have severe or rapidly progressing glaucoma Talk to your doctor to see if this trial is right for you.
