Bionic eye' implant restores men's sight
What was done?
The retinal implants were developed by Retina Implant AG in Germany to treat people with retinitis pigmentosa. Each implant contains a microchip containing 1,500 tiny electronic light detectors. During the trial, the implant was placed beneath the retina at the back of the patient’s eye. The patient’s optic nerve (the nerve that transmits visual information from the retina to the brain) was then able to pick up electronic signals coming from the microchip.
