XEN Glaucoma Gel Stent Versus Trabeculectomy

This study is comparing two surgical procedures for treating glaucoma — a condition where pressure inside the eye damages the optic nerve: the XEN gel stent (a minimally invasive implant) versus trabeculectomy (a traditional surgical procedure that creates a new drainage channel). The goal is to see which approach better lowers eye pressure over time with fewer complications. **You may be eligible if:** - You have open-angle glaucoma (primary, pseudoexfoliation, or pigmentary type) - Your surgeon determines you are eligible for either procedure - You are 18 or older - You have reasonably good visual acuity - You understand the procedure and are willing to attend follow-up appointments **You may NOT be eligible if:** - You have a significant cataract - You have had recent cataract surgery in the eye being treated (within 1 month) - You have had prior glaucoma surgeries that would interfere Talk to your doctor to see if this trial is right for you.
