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]
