Bionic eye improves macular degeneration patient's sight
Surgeons in Manchester have performed the world's first bionic eye implant in a patient with the most common cause of sight loss in the developed world.
Ray Flynn, 80, has dry age-related macular degeneration which has led to the total loss of his central vision.
He can now make out the direction of white lines on a computer screen using the retinal implant, which converts video images from a miniature video camera worn on his glasses.
The BBC's Medical Correspondent Fergus Walsh went to meet Ray Flynn and the team behind his treatment.
