I did two separate searches and didn't find anything relating to this so here goes. Apparently two British men have received the gift of sight, they are able to perceive light and even some shapes from the devices which were fitted behind the retina.

Chris James and Robin Millar of the United Kingdom both lost their vision after birth because of a genetic condition known as retinitis pigmentosa, in which light-sensitive cells in the eye stop working. Now, surgeons have partially restored vision to both men with tiny electronic chips that promise to help the blind see the same way cochlear implants have helped the deaf hear. Teams of doctors at the Oxford Eye Hospital and King’s College Hospital in London embedded the small square chips—0.12 by 0.12 inches—in a thin sheet of tissue at the backs of the men’s eyes. As soon as they were switched on, the chips began performing the duties of defunct photoreceptors—also called rods and cones—converting light into electrical impulses that travel to the brain. A thin cable threaded beneath the skin connects the chip to a battery pack, which also sits under the skin near the ear.

Saw this on the BBC news recently, and was mightily impressed. Comming as it does on the same week as we see the brave march of a paralyzed woman, doggedly determined to finish the London Marathon on crutches, using a hybrid assistive limb unit on her legs to keep her going, this is an awesome month for implanted and assistive technologies.

I think it should be the aim of every medical practitioner, to lobby for greater cash input to these technologies for the benefit of all persons who loose the use of a sense, or a limb. We have long used tools to increase our reach, our ability to apply strength. I see these advances as another step man is taking to apply his use of tools to strengthen those that fate has weakened, and am intensely interested to see where this path leads us in the future.
