Bionic eye changing woman's life after losing sight

A woman who has gradually been losing her sight for years has been describing the joys of being able to see again after being fitted with a bionic eye.

Rhian Lewis, from Cardiff, Wales, was given the retinal implant as part of a trial which could go on to benefit thousands of people suffering from sight loss.

The 49-year-old had an operation to implant a tiny 3x3mm chip into her right eye.
