Bionic Eye

A bionic eye (retinal implant) restores some vision in blind individuals by electrically stimulating the retina, optic nerve, or visual cortex.

Overview


Bionic Eyes are artificial devices designed to restore some level of functional vision in individuals with partial or total blindness by electrically stimulating the retina, optic nerve, or visual cortex.


Types of Visual Prostheses


There are several types of visual prostheses under development, targeting different parts of the visual system:


Retinal Implants

These devices are implanted directly onto or beneath the retina and stimulate the remaining healthy retinal cells. Examples include:

  • Argus II (epiretinal)

  • Alpha IMS (subretinal)

  • PRIMA (photovoltaic subretinal)


Optic Nerve Implants

These devices stimulate the optic nerve directly using a cuff electrode. The Microsystem-based Visual Prosthesis (MIVP) is an example of this approach.


Cortical Implants

These devices bypass the eye and optic nerve altogether, stimulating the visual cortex directly. Examples include:

  • Intracortical Visual Prosthesis

  • Dobelle Eye
