  Cataracts

If your doctor has told you that you have a cataract, don't be alarmed. Over half of those over 65 have some cataract development and most cases can be treated successfully with surgery.
  Despite what you may have heard, a cataract is not a skin that grows over your eye. A cataract is a clouding of part of your eye called the lens. Your vision becomes blurred or dim because light cannot pass through the clouded lens to the back of the eye.
  
Cataracts can form at any age, but most often develop as people get older. In younger people they can result from an injury, certain drugs, long-standing inflammation or illnesses such as diabetes.

Some symptoms:

  • 'I'm not seeing as well as I used to'.
  • You may notice that some things seem blurred round the edges, or that your glasses seem dirty or scratched.
  • The cloudiness in the lens may occur in more than one place, so that the light rays which reach the retina are split, causing a double image.
  • You may find that bright light or very sunny days make it more difficult to see

  The most effective treatment for cataracts is a small operation to remove the cloudy lens. This cannot be performed by laser, although laser treatment is sometimes needed afterwards. Diets or drugs have not been shown to slow or stop the development of the cataract.
  When the cloudy lens has been surgically removed it is usually replaced by a plastic lens so that the eye can focus properly.

  In the past, eye specialists often waited until the cataract became `ripe' before suggesting you had it removed. Nowadays, with
modern surgery the operation can be carried out at any stage of the cataract's development. If visual impairment interferes with
your ability to read, to work, or to do the things you enjoy then you will probably want to consider surgery.
   For most people, it is possible to have your operation and go home on the same day, as long as you have someone to look after
you at home. Sometimes surgery will mean a short stay in hospital.

What happens in the operation?

Just before the operation you will be given eye drops to enlarge your pupil and something to help you relax if you want this.
Normally cataract surgery is performed with a local anesthetic and some sedation. The local anesthetic numbs the area that is being operated on. You will be wide awake but feel nothing in your eye. Usually the eye specialist will explain what is happening as the operation goes along, and a nurse will be there to hold your hand and make sure you are all right.

The operation is performed with the aid of a microscope through a small cut in the top of the eye. This is closed using small
stitches at the end of the operation. The operation generally takes 30 minutes. A pad or shield will probably be put over your eye to protect it from accidental rubbing and bumping after the operation.

I want to reassure you that your eye is not taken out of its socket during surgery. The operation is not painful and often, stitches are not needed.

After the operation:

  Your sight will usually improve within a few days, although complete healing may take a month. It is a good idea to have
some help at home if you can, especially if you find it difficult to put your eye drops in. You will need to take it easy for a couple
of weeks so that your eye can heal.
