Long-term eye pressure control with a glaucoma implant

This trial is checking how well the Hydrus implant works over a very long time—up to 14 years after surgery. The Hydrus implant is a tiny device placed in the eye to help lower pressure and prevent blindness from glaucoma. Researchers want to understand how this treatment performs in real life over many years, including whether patients still need other eye pressure medications or additional surgeries.

Glaucoma damages eyesight by building up pressure inside the eye, and patients need long-term pressure control to avoid going blind. While doctors know how this medication works for up to 5 years, nobody has studied it for 8 to 14 years yet, so this trial will show what happens to patients' eyes over the long term.
