Microstent offers new hope for stubborn glaucoma
NCT ID NCT03267134
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a small device called the Hydrus Microstent in 217 adults with open-angle glaucoma that was not well controlled with other treatments. The goal was to see if the implant could safely lower eye pressure. After 12 months, many patients had a significant drop in eye pressure while using the same or fewer eye drops.
