A woman left partially blind in one eye after an acid attack has had her sight restored following stem-cell surgery.

Doctors at the Queen Victoria Hospital in West Sussex took tissue from an anonymous donor, grew it and then stitched it into Katie Piper's damaged eye.

She told Victoria Derbyshire that the operation has been successful.
