Visual prosthesis

9. Februar 2017 - Eye, Ophthalmology

A visual prosthesis , many referred to bionic eye , is an experimental visual device that attempts to restore functional vision in those who suffer from blindness or partial blindness.


Many visual prostheses have been developed based on cochlear implants or bionic ear devices, a type of neural prosthesis in use since the mid-1980s.

The idea of ​​using electric current (for example, electrical stimulation of the retina or visual cortex) to provide sight goes back to the 18th century, discussed by Benjamin Franklin , 1 Tiberius Cavallo , 2 and Charles LeRoy. 3

Argus retinal prosthesis

The Argus retinal prosthesis is an electronic retinal implant produced by the company Second Sight , it is designed mainly to improve the vision of people with severe cases of Retinosis Pigmentaria disease . In February 2013, Argus II became the first commercial visual prosthesis to be approved for use in the United States . 4
