Device gives sight back to three blind people

A GROUND-BREAKING retinal implant has allowed three blind patients to see shapes and objects for the first time since they lost their sight to an inherited disease.

Before having the device fitted, each had a limited ability to perceive bright light but were completely unable to recognise shapes.

Within days of undergoing surgery, all three could locate objects placed on a table, including a cup, a saucer and different geometric shapes.
