NCT ID NCT06246136
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two devices used during cataract surgery to treat open-angle glaucoma. About 194 adults with mild to moderate glaucoma and cataracts will receive either the ELIOS device or a competitor device. The main goal is to see which one lowers eye pressure more effectively after 12 months.
