What is a cataract?
Over half of those over 65 have some cataract development and most cases can be treated successfully with surgery. A cataract is not a skin that grows over the eye. A cataract is a clouding of part of the eye called the lens. Vision becomes blurred or dim because light cannot pass through the clouded lens to the back of the eye.
What causes a cataract?
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.
What are the symptoms?
Symptoms can include:
What can be done?
The most effective treatment for cataracts is a small operation to remove the cloudy lens. Diets or drugs have not been shown to slow or stop the development of the cataract.
What is a lens implant?
When the cloudy lens has been surgically removed it is usually replaced by a plastic lens so that the eye can focus properly. Occasionally a doctor will decide an eye is not suitable for a lens implant. In these cases contact lenses or special glasses will be prescribed instead.
What happens after the operation?
Your sight will usually improve within a few days, although
complete healing may take several months. It is a good idea to
have some help at home if you can, especially if you find it difficult
How long you are off work will depend on the job
that you do.
