The scientists explain that the bionic eye will be affective for individuals who once had sight, since their brain knows how to process visual information. The unfortunate people who were born blind do not have the neurological capability to process the data received via the wire. Furthermore, the optic nerve must be at least partly functional. Otherwise, the data will not be fully processed. For many individuals that were born blind, this is a problem as well, since their optic nerve has never been used. However, most of these individuals have a natural compensation mechanism, in the form of enhanced senses, such as hearing and touch.

The researchers note the device has some limitations, and it will not restore perfect vision. However, they are sure it will give people the advantage of having a general sense of their surroundings. Hopefully, the technology may enable people to recognize faces and facial expressions. "The thing is to significantly improve the quality of life for blind patients," said Joseph Rizzo of the Massachusetts Eye and Ear Infirmary, who has co-directed the project with MIT's John Wyatt since 1988.

TFOT has covered the discovery of the last retinal movement-detecting cell and the latest stem-cell research that has improved our understanding of blindness. Another article recently published by TFOT deals with mind controlled bionic limbs, which were designed to assist disabled people in their daily lives. 

Thirty six researchers joined collaborated on The Boston Retinal Implant Project, including scientists from MIT, the Massachusetts Eye and Ear Infirmary, and the V.A. Medical Center in Boston. For more information about the project, see the Boston Retinal Implant Project website.
