What is a cataract?
A cataract is a gradual clouding of the eye's natural lens, which sits just behind the pupil and focuses light onto the back of the eye. As the lens loses its clarity, vision becomes misty, colours fade and glare becomes more intrusive. Cataracts are extremely common with age — and modern surgery is one of the safest and most effective procedures in medicine.
