Cataracts and Surgical Treatment:
The eye is like a camera - it has a lens at the front and a film at the back. A cataract is a hazy lens and the lens sits in a bag behind the iris (or coloured part of the eye).
The operation is performed as a day case procedure. The pupil is dilated with drops, then the eye is put to sleep (anaesthetised). A small cut is made at the side of the eye. The lens (cataract) is removed from the bag through the dilated pupil. A new folding lens is then inserted, which unfolds inside the bag.
