SCIENTISTS
have developed a tiny implant , no bigger than a pinhead ,
which sits inside the cornea to reverse vision problems in aging
eyes .
With the age ,some people's 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 .
The new implant slightly increase the curvature of the cornea,which allows the eyes to focus again.This new technique ,known as a' Raindrop corneal inlay' was developed by scientists at Revision Optics in California.The first operations have now been carried out at a clinic in Warwickshire .The inlay is called Raindrop because it is in the shape of a droplet and is made of hydro-gel, a substance which is also used in contract lenses. Hydro gel is 80 percent water which makes it more compatible than other implants.
