NCT ID NCT03392324

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early feasibility trial tests a new retinal implant called PRIMA in 5 people with advanced dry age-related macular degeneration who have lost central vision. The device is surgically placed in the eye to stimulate remaining retinal cells. Researchers are checking if it is safe and whether it can improve near vision and quality of life.

Active substance

PRIMA retinal implant (device)

What this could lead to

If it works, this could point toward a way to restore some vision in people with advanced dry age-related macular degeneration.

What could go wrong

This is a very early, small trial with only 5 participants. The implant may not improve vision enough to be useful, and surgery carries risks like infection or device failure.
