The eye is a delicate thing. Most ocular implants that get too hands-on with your squishy sightballs cause rejections problems, but a new implant developed by the Boston Retinal Implant project shrinks the components significantly, allowing your eye to take on its cyborg enhancements without casting them off violently as unwelcome invaders.
For people with retinal diseases like acute macular degeneration or retinitis pigmentosa, vision is impared because the retina's photo-sensing cells become unreceptive to light; however, the nerves leading from the eye to the brain (the most Monster cables) are generally left in good shape. Implants like this one stimulate the sleepy retina cells with electric current, which is generated from the wirelessly-powered coil surrounding the iris and processed by a microcontroller in the tiny titanium case that sits on the outside of the eyeball.
This iteration is the first to have components small enough to be mostly external, which is less complicated from a bio-rejection standpoint. So to go where lasers can't, hopefully Eye 3.0 tech like this will pick up the slack. [Technology Review]
