Cataracts

A cataract is clouding or opacity of the lens inside the eye. It causes gradual blurring of vision and often glare.

  • Inside your eye, behind the iris and pupil is a lens. In a normal eye, this lens is clear. It helps focus light rays on to the back of the eye (the retina), which sends messages to the brain allowing us to see.

    When cataract develops, the lens becomes cloudy and prevents the light rays from passing on to the retina. The picture that the retina receives becomes dull and fuzzy.

    Cataract usually forms slowly and most people experience a gradual blurring of vision.

  • Most forms of cataract develop in adult life. The normal process of ageing causes the lens to harden and become cloudy. This is called age-related cataract and it is the most common type. It can occur at any time after the age of 40.

    Although most cataracts are age related, there are other types, including congenital (present at birth), drug induced (steroids), and traumatic (injury to the eye). Cataract is also more common in people who have certain diseases such as diabetes.

  • ​Cataract surgery at Moorfields Eye Hospital was recently profiled on the Islam Channel’s Health Show Live. You may find this video useful.
