British woman gets bionic eye
Rhian Lewis, a British woman aged 49, is the first Briton to get a bionic eye. A chip was implanted in the back of the retina, which allowed her to see for the first time in six years.
The woman started losing her eyesight when she was 5 years old. Now she can read the time of a clock, experience sunshine and even recognize her two 18-year old twins , which she hadn't clearly seen for a few years.
The bionic eye works by gathering light and sending it to the brain, where it is turned into images.The chip has 15,000 light sensors that replace the cells in the retina. It is connected to a tiny computer that sits in the back of her ear. The revolutionary invention was manufactured by a Germany firm. Lewis is the first person outside of Germany to receive the chip.
The disease which was passed down to Lewis from her parents destroys the light cells in the retina. She became completely blind on one eye and could hardly see anything with her other eye. In her first interview after the successful operation she described the joy of being able to see again.
What Lewis first saw first were simply flashes of light. In the course of a few weeks, the brain learns to change those flashes into objects and shapes she can recognize. She can change contrast and brightness with a small gadget that she holds in her hand.
The operation, performed in an Oxford hospital, took about 6 hours. Surgeons are also amazed because for the first time they have been able to activate a part of the brain that hasn't been working for some time.
The bionic eye is hope for thousands of people who suffer from losing their eyesight, especially when they become older.
