FDA Approves Artificial Eye

This Argus II helps with retinitis pigmentosa, a disease where the retina gradually degenerates.

How does it work?

The patient wears glasses with an attached video camera that captures images of the surrounding area. These images become an electrical signal which is processed by the video processing unit. The signal is then wirelessly delivered to the eye stimulating the retina. This electrical stimulation of the retina is recognized by the brain as spots of light.

How well does it work?

From the clinical study:

“Results of the clinical study showed that the System helped subjects:  identify the location or movement of objects and people; recognize large letters, words, or sentences; and helped in other activities of daily life, such as detecting street curbs and walking on a sidewalk without stepping off.” - FDA

Disclaimer: “The effectiveness of this device for this use has not been demonstrated.” – Second Sight

Hopefully, as the technology continues to develop, we’ll be able to gain more of our sight back.
