Emerging Prostheses Attempt Vision Restoration
Low-resolution retinal implants aimed at helping the blind gain mobility are
getting ready to appear on the market. 

From: R&D Magazine - June 2004 - page 30

Numerous researchers are dedicating their time and efforts to develop
microelectromechanical systems (MEMS)-based visual prostheses that will
improve the quality of life of visually impaired individuals. Three
approaches are generally being explored, with the prosthesis being implanted
in the brain's visual cortex, the optic nerve, or in the retina. A retinal
prosthesis can be fixated either on the retinal surface (epiretinal) or below
the retina (subretinal).
