London: Scientists have developed a tiny implant, no bigger than a pinhead, which sits inside the cornea to reverse vision problems in ageing eyes. As some people age, their ability to switch focus between near and distant objects diminishes, a condition known as presbyopia.

It can skew the perception of depth and makes reading in poor light impossible. Now, scientists have developed a tiny implant that sits inside the cornea and slightly increases its curvature, to allow the eye to focus again. Known as a Raindrop corneal inlay, the technique was developed by scientists at ReVision Optics in California but the first operations have now been carried out at a clinic in Leamington Spa, Warwickshire, 'The Telegraph' reported.
