The 'everyday miracle' of cataract surgery

The first ever cataract operation was performed in 1950 by Harold Ridley, replacing the eye's natural lens with one made out of plastic.

At the time the operation was very controversial, many of Mr Ridley's contemporaries disapproved.

However the surgery he pioneered has saved the sight of more than 200 million people worldwide.
