There are about 285 million people in the world who are visually impaired. Out of them about 39 million people are completely blind and the remaining 246 million people have low vision. Now, there is hope for these people. Technology can help them to get their vision back. In a pioneering research work, the vision of two British men was partially restored after a micro-electronic chip was implanted in their eyes behind the retina. This tiny 3mm square microelectronic chip has a large number of light-sensitive pixels which perform the function of the photoreceptor rods and cones. The said chip was placed behind the retina from where an ultra-thin cable connected them to a control unit under the skin behind the ear. This chip is similar to the ones found in mobile phone cameras. The two patients, Chris James and Robin Millar received this treatment as a part of a clinical trial carried out at the Oxford Eye Hospital and King’s College Hospital in London under the guidance of Professor Robert MacLaren and Mr. Tim Jackson.
