Bionic implant shows promise for restoring sight in dry AMD
NCT ID NCT03333954
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a tiny implant called the PRIMA Bionic Vision System in 5 people with advanced dry age-related macular degeneration who had lost central vision. The implant is placed under the retina and uses electrical stimulation to replace damaged light-sensing cells. The goal was to see if the device could create visual perceptions, potentially helping patients see shapes and objects again.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- PRIMA Bionic Vision System (sub-retinal implant)
- What this could lead to
- If it works, this could provide partial vision restoration for people blinded by dry age-related macular degeneration.
- What could go wrong
- This is a very early feasibility study with only 5 participants, so results may not apply widely. The implant only partially restores vision and does not cure the underlying disease.
