Blind man sees after having a tooth implanted into his eye.

During the procedure, a minute section of a patient's tooth is removed, reshaped and chiselled through to grip the man-made lens which is then placed in its core.

It is implanted under an eyelid where it becomes covered in tissue.

The process requires a living tooth as an implant because doctors suggest there are chances the eye would reject a plastic equivalent.

So a canine - which is the best option due to its shape and size - was taken out of Mr Jones' mouth.

A patch of skin is then taken from the inside of the cheek and placed in the eye for two months, where it gradually acquires its own blood supply.

The tooth segment is finally transplanted into the eye socket. The flap of grafted skin is then partially lifted from the eye and placed over its new sturdy base.

Finally, surgeons cut a hole in the grafted cornea to let light through.
