After 20 years of becoming progressively blind, Chris James is being given the chance to see again.
He suffers from retinitis pigmentosa a condition which affects many thousands of people in Europe and is currently incurable. He is one of the patients participating in a trial of an implant, known as a ‘bionic eye’, carried out at the John Radcliffe Hospital in Oxford, England.
During an operation a chip, made by the German company Retina Implant AG, is placed in the patient.
The chip, which is similar to those found in cellular phone cameras, allows the conversion of light passing through the eye into electrical impulses, which the brain can then interpret as images.
