A wireless brain implant designed to restore artificial vision has been implanted in a third blind participant as part of an ongoing US study.

The Intracortical Visual Prosthesis (ICVP) device bypasses the eye entirely, directly stimulating the brain's visual cortex to generate patterns of artificial sight.

The system uses multiple miniaturised wireless stimulators implanted into the brain, each carrying electrodes that deliver controlled electrical pulses.
