An eye implant made from human embryonic stem cells could treat a common cause of blindness. Because of that, study author Amir Kashani says, he didn’t expect an improvement in vision. Researchers at the US Food and Drug Administration inserted stem-cell membranes into the eyes of Two people with advanced dry macular degeneration, a leading cause of blindness. During a year , their eyesight either grew no worse or improved slightly. Researchers at the US Food and Drug Administration in London have developed a similar stem-cell patch for patients with the wet form of macular degeneration. However, both studies were small, with no control groups, and the Moorfields Eye Hospital has yet to approve embryonic stem-cell treatments.
