Blind Paralympian Tim Reddish who has 23 golds can finally see all his medals... with a new bionic eye He's won more than 50 medals swimming for his country, but Tim Reddish only ever had the pleasure of seeing a handful of them. Diagnosed with a degenerative eye condition at the age of 31, the former Paralympian went totally blind 17 years ago. But thanks to the fitting of a bionic eye, the 55-year-old can now see his haul in all its glory. Mr Reddish - currently the chairman of the British Paralympic Association - told yesterday how a revolutionary retinal chip is enabling him to make out shapes and read a clock face. The eight-hour procedure to implant an artificial retina brings hope to thousands who suffer with similar conditions. It costs up to £100,000 per patient and builds on previous attempts to produce a bionic eye using a camera and transmitter linked to a pair of glasses as a means of relaying images to the artificial retina. Mr Reddish is one of nine totally blind UK patients who took part in a trial of the chip at the Oxford University Eye Hospital and King's College Hospital, London. He said of the moment medics switched on the chip: "It was as if a match had been lit in a dark room - it was unbelievable. In the lab tests, when there are objects on a table, and the lighting is bright, I can tell you how many objects there are, and most of the time I can read the clock. To be able to see even the vaguest of blurry outlines of the medals I won is a terrific achievement and means a lot to me. Mr Reddish, from Nottingham, began losing his sight after developing retinitis pigmentosa, an inherited disease that destroys the retina and which affects an estimated 20,000 in the UK. The father-of-two competed at three Games with the British Paralympic swimming team. He scooped silver and bronze in 1992 in Barcelona, silver and bronze in Atlanta in 1996 and a silver medal in Sydney in 2000. He also won 11 gold world blind swimming championships medals during an illustrious career, before becoming performance director for the Paralympic swimming team at the Athens and Beijing Games. He was honoured with an MBE in 2001 and an OBE in 2009, both for services to disabled sport. Last October, medics inserted a 3mm square, light sensitive chip under the existing retina in his right eye.

Each pixel mimics the function of the photoreceptor rod and cone cells in the eye which were destroyed as a result of Mr Reddish's condition. Robert MacLaren, a consultant retinal surgeon involved in the trial, said: "This technology has proven that it is possible to restore some sight to a person who before was completely blind. It is a huge step forward but there is still much more work to be done. Professor MacLaren said because it is a trial, the chips were implanted in only one eye of each patient. The trial was funded by a grant from the Department of Health's National Institute for Health Research, while German chip manufacturer Retina Implant AG also provided its devices for free.
