Subretinal Photovoltaic Implant to Restore Vision in Geographic Atrophy Due to AMD

The 60-second view

What problem?

Geographic atrophy destroys central vision and no therapy had been shown to restore it.

What did they do?

Implanted a photovoltaic microarray under the retina in 38 participants; camera glasses project near-infrared images onto it.

What changed?

26 of the 32 participants assessed at 12 months improved by at least 0.2 logMAR with the system on.

Why does it matter?

It is the strongest clinical evidence so far that a neural prosthesis can restore a lost sense at a scale relevant to a common disease.

Method

Participants

38 people with geographic atrophy and visual acuity of at least 1.2 logMAR; 32 assessed at 12 months

Interface

Subretinal photovoltaic implant with near-infrared projecting glasses

Signal

Photovoltaic stimulation of inner retinal neurons

Task

Visual acuity with and without the system at 6 and 12 months

Decoder

Not applicable; image processing in the wearable

Results

26 of 32 (81%)

Clinically meaningful improvement at 12 months

Participants implanted

Strength of evidencePeer reviewed, open-label, multicentre, baseline-controlled. Serious adverse events related to the procedure or device were reported and are detailed in the paper.

Figures are quoted from the published abstract and were checked on 3 Oct 2026.

Limitations

• Open-label, single-group design.
• Six participants were not assessed at 12 months.
• Restores central form vision through glasses, not natural sight.

What this could enable

The first authorised device for restoring form vision in this condition, CE-marked in 2026.
