A bionic eye has restored sight to the blind in groundbreaking tests, according to research published in the Proceedings of the Royal Society B, which describes how the implant allowed two blind men and a woman to see shapes and objects for the first time since losing their sight to retinitis pigmentosa.
Professor Eberhart Zrenner, of Germany's University of Tuebingen, and colleagues at private company Retina Implant AG initially tested their sub-retinal chip on 11 people.
The Daily Mail points out that "the device...consists of a very thin microchip, just 3mm by 3mm in size and packed with 1,500 light sensors designed to replace those in the retina lost to disease.
David Head, chief executive of the British Retinitis Pigmentosa Society, said that it was exciting news but that it was early days.
