Cataracts and Vision

cataracts and vision

A cataract refers to the clouding of the normally clear lens situated behind the pupil (dark centre) of the eye. Cataracts occur as a natural consequence of ageing, although can be worsened by smoking, long exposure to bright sunlight, trauma and some medications. Cataracts can be treated by cataract surgery. The cataract is removed and a clear artificial lens is inserted to allow you to see well.

How do I know if I need cataract surgery?

Cataracts cause a reduction in:

  • quality of vision
  • colour appreciation
  • distance and reading vision, and
  • night vision

These changes may interfere with many of your activities, such as driving, watching TV, working on the computer, reading the newspaper or walking down the street.

At Glaucoma Care your Ophthalmologist can assess your cataract(s). After discussion with your Ophthalmologist you should decide together when to have surgery based on how much the cataract(s) interfere with your life.

What are the benefits of cataract surgery?

Performed by our surgeons, cataract surgery results in excellent vision. It will improve the colours you see, the sharpness and quality of your vision. In some patients with glaucoma or raised eye pressure, cataract surgery can widen the drainage angle, improving the drainage of fluid from the eye to lower the eye pressure.

Are there drops, tablets, or other lifestyle changes that can treat cataract(s)?

No - at present cataracts can only be treated by surgery.

Will I still need my glasses after surgery?

Our team will aim to provide crisp vision without glasses, however you may still need glasses for very fine print, especially for reading. If you prefer, potential spectacle-independent options can be explored that allow both near and distance vision.
