Artificial lens implant promises to give patients 'HD vision'
Implanted lenses may be old hat compared to newfangled sight restoration techniques involving radiation beams and teeth, but it looks like some eye surgeons in the UK have now come up with a few new tricks that promise to let patients see better than ever. The new process apparently starts out like a standard procedure for cataracts, but makes use of lenses made from light-sensitive silicone that can be fine tuned several times after the surgery, eventually giving the patient "HD vision" that's said to be better than 20/20. The lenses can apparently even be adjusted for either bifocal or varifocal use, eliminating the need for some patients to wear glasses at all. Head on past the break for a video. [Thanks, Esevila]
Researchers develop eye-implantable camera
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."Read - NewScientist blurbRead - Patent application
