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:
 |
Blurred Vision: "I'm not
seeing as well as I used to" people may notice that some things seem
blurred round the edges, or that your glasses seem dirty or scratched.
|
|
Seeing Double: The cloudiness in
the lens may occur in more than one place, so that the light rays that reach
the retina are split, causing a double image.
|
|
Poor Vision in Bright Light:
Bright light or very sunny days may make it more difficult to see.
|
|
Change of Colour Vision: As the
cataract develops, its centre becomes more and more yellow, giving
everything you see a yellowish tinge.
|
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 to put your eye drops in.
|
You will need to take it easy for a couple of weeks so your eye can heal. |
|
Avoid rubbing your eye; wear an eye shield if you are a restless
sleeper. |
|
Don’t do any heavy lifting, and avoid strenuous exercise and swimming. |
|
You can do light housework or cooking but try to get some help if you can. |
|
You don’t need to stay indoors but take care if it is windy, in case
anything blows in your eye. |
|
Wash your hair leaning backwards rather than forwards. |
|
Avoid eye make-up for six weeks. |
|
You can resume your sex life a week or two after the operation. |
|
Avoid driving until your surgeon tells you it is safe. |
|
New glasses are usually prescribed four to eight weeks after the
operation. |
|
How long you are off work will depend on the job that you do. Ask your eye
specialist about this. |
