Laser treatment versus surgery for glaucoma that doesn't respond to eye drops

Glaucoma is a serious eye condition where pressure builds up inside the eye and damages the nerve that allows you to see. When eye drops alone don't work well enough, doctors can try surgery. This trial is comparing two different surgical approaches: one uses a laser to reduce fluid production in the eye, while the other creates a small drain to let excess fluid escape. The goal is to see which method works better and is safer for patients like you who have already had cataract surgery.

Many patients with glaucoma can't control their eye pressure with medications alone, even when using multiple eye drops. Surgery becomes necessary, but doctors want to know which surgical approach is safest and most effective for patients who have had cataract surgery, since they may respond differently than other patients.
