ITV News Correspondent Helen Keenan talks to the vet who performed the procedure
It was a tricky procedure, needing very careful handling and plenty of anaesthetic, but the eye of a fully grown Sumatran tiger has indeed been saved.
Ratna was given an operation at a zoo in Cambridgeshire to save her left eye.
Two months on, the procedure has been hailed a roaring success after she was given the all clear.
The operation is thought to be the first of its kind anywhere in the world on such a large animal.
