Preparing for cataract surgery

What is cataract surgery?

A cataract forms when the natural lens in your eye becomes cloudy. Modern surgery allows the damaged lens to be removed and replaced with an artificial lens.

What type of anaesthetic will I have?

  • Most people are awake during the procedure and have local anaesthetic to numb the eye.
  • This may either be in the form of drops, or a numbing injection around the eye.
  • Occasionally people require some sedation (medicine to relax you).
  • A small number (1 per cent or 1 in 100 people) may need a general anaesthetic for medical reasons (anaesthetic drugs make you unconscious, so you are completely unaware throughout your operation).
  • Your anaesthetist will discuss with you the best options for you, based on your age, health and any difficulty the surgeon anticipates.
