Artificial corneas grown in the laboratory have been transplanted into patient's eyes for the first time in an operation in the year 2010 that offers hope to millions of partially sighted people.
The new technique involves growing human tissue or collagen in the laboratory and then shaping it using a contact lens mould. Damaged and scarred tissue from the front of the eye is then removed and the "biosynthetic" replacement is stitched in its place. Eventually existing cells and nerves in the eye grow over the artificial cornea incorporating it fully into the eye.
The first trials of the operation have shown that it is just as successful as live tissue transplantation and in some cases patients have had their sight fully restored.
