Surgeons at Oxford Eye Hospital implanted an electronic ‘bionic eye’ in a blind woman which has helped the blind woman restore her lost sight partially. The woman said she could now make out the time on a clock face.
BBC Wales said that a group of surgeons at Oxford Eye Hospital implanted a small light-sensitive microchip at the back of Rhian Lewis's right eye. It took around eight hours for a team of surgeons to implant the chip at the back of the lady’s eye.
Rhian Lewis, 49, has had the condition retinitis pigmentosa since she was five years old. The condition deteriorated her eyesight as she got older and until she was completely blind in her right eye, and has a very limited in her left eye.
Mrs Lewis underwent the surgery in June, 2015, after surgeons implanted the chip as part of a trial at Oxford’s John Radcliffe Hospital. Further during follow-up tests, Mrs Lewis was asked to look closely at a large cardboard clock to see if she could tell the time correctly. She said she was able to tell what time was in the clock.
Mrs Lewis was then taken to the cloisters of New College, Oxford, to see if she could make out its features. “I walked up the street, and the lady from social services said to me to point out anything I thought might or might not be there”, said Mrs Lewis.
The thing she said she saw first was a silver car. She said at first, she was not able to believe that she can now see because the signal was really strong, and that was the sun shining on the silver car. Mrs Lewis is the first patient outside of Germany to be fitted with the latest generation of the light-sensitive chip.
