“Bionic” eye restores vision after three decades of darkness

March 5, 2009

When vision fails, it’s often the result of damage to the eye caused by an injury or degenerative disease. In an attempt to restore such vision loss, researchers for more than a decade have been working to develop an optical prosthetic that can restore sight by delivering images directly to the brain. And it appears they succeeded. The BBC reports that a 73-year-old man identified only as Ron, who received an optical implant at Moorefields Eye Center in London last summer, can see again for the first time in 30 years.
