Eye implant may delay cataracts after vitrectomy
NCT ID NCT05026632
First seen Jun 27, 2026 ยท Last updated Jun 27, 2026
Summary
This study tests a special implant placed in the eye during vitrectomy surgery to see if it can safely slow down cataract formation. About 30 adults who need vitrectomy and already have some cataract will receive the implant. The goal is to delay cataract progression, possibly reducing the need for future cataract surgery.
