A teenager whose sight was almost totally gone had it restored with special contact lenses.
Kristian Cooke, aged 14, had been diagnosed with keratoconus, a condition of the cornea, when he was ten.
This meant he was increasingly unable to read, watch television or play games and sport and at 14 was on the threshold of being registered blind.
Internet research by his mother, Sarah Adams, led to finding a specialist through a self-help group and an operation at Moorfields Eye Hospital to insert the scleral contact lenses into Kristian"s eye.
He has now passed his GCSE maths and physics - three years early - and intends to go to Cambridge University when he has his A-levels under his belt.
Keratoconus is a degenerative disorder that leads to a thinning of the cornea and which leads it to become more conical, when it should be shaped in a gentle curve.
