Professor James Wolffsohn from Aston University in the United Kingdom imagines that within the next decade, the cure to near- and farsightedness will not only exist, but will actually be within reach. While the underlying idea of replacing biological lenses with minty-fresh artificial ones isn't necessarily new (think cataract surgery), Wolffsohn's efforts will allow patients to focus both near and far, instead of just plain old, boring far. While the details on how the lenses work are a little scant (read non-existent), apparently eye muscles squeezing the "ultra-flexible" devices allow the actual focusing to occur. The professor has been working with opthology companies to commercialize the specs, and envisions the procedure costing less than £1,000 within the next five to ten years. Sounds good to us, because fancy new lenses or not, as people who stare at computer screens all day, the odds of us going under the laser at some point are a tad on the high side.

Most of the bionic eye systems we've seen involve clunky glasses-cam headgear, but the implantable camera now being developed at UCLA does it straight Terminator-style and keeps your face unencumbered. The camera, which researcher Michelle Hauer and her team recently filed a patent for, is small enough to be implanted directly on the eye's lens, and feeds image data to a chip at the back of the eye, where it can either be fed into the optic nerve to aid the blind, or just into a portable hard drive to aid the creepy. Hauer says power will come from on an onboard battery, but we're more interested in the mention of "optical control signals" in the patent application -- and by "interested" we mean "terrified of a zombie android army."

Researchers at the University of Southern California's Doheny Eye Institute have snagged the all-important FDA approval need to begin clinical trials of their bionic eye implant, joining a growing number of other groups following in Lee Majors footsteps. Once underway, between 50 and 75 patients suffering from retinitis pigmentosa and macular degeneration will be outfitted with the implant, which has already seen some degree of success in limited testing. As the image above shows, in its current form at least, the device isn't completely implantable, also consisting of a small camera mounted on a pair of glasses that's wired to a handheld device. It works by processing images from the camera and wirelessly transmitting them to a receiver implanted in the eye, which in turn sends signals to a series of electrodes that stimulate the retina, sending the information to the brain, all of which happens in real time. While it won't restore full sight, the researchers say patients should be able to detect light and distinguish objects from one another. If all goes as planned, they also foresee the device being commercially available shortly after the trials are complete, although it obviously won't come cheap, with an expected price tag of $30,000. Let's just hope a mirror shades version isn't too far behind.

It's a bit odd, even to us, that bionic eyes aren't really that fresh of a topic these days, but they're still dang awesome, and it looks like a new project by the Bionic Eye Foundation at Sydney's Prince of Wales Hospital is doing particularly well. The bionic eye works in much the same way as a cochlear implant does, by implanting small electrodes to stimulate the retina, which then sends images on to the optic nerve. The view is generated by a video camera mounted on a pair of glasses, and while it's barely managing flashes of light for patients so far, the method seems plenty promising. There isn't much hope yet of offering full sight, but basic outlines of objects should be possible in the near future, and work is even being done on an implant that sends messages directly to the brain, in case a patient's optic nerve does not function. We're not sure how long it'll take for this technology to get out of the lab on onto the street, but clinical trials are sure a good sign.
