Cataracts 

Cataracts - What are they? 

Cataracts occur when the lens inside your eye becomes increasingly opaque resulting in ‘misty’ or ‘foggy’ vision. The cause of cataracts is age; however, they can be worsened by steroid use, diabetes or sunlight.

What are some of the effects of cataracts?

Someone with early stages of cataracts may notice a ‘film’ in their everyday vision. Often, things that used to look black and white now look grey and colours are perceived as dull. In the early stages of cataracts, new spectacles may improve vision but, as the cataract worsens, spectacles often will not provide any significant improvement. Your optometrist will be able to advise you further on this. You may not be aware of cataracts in your vision because changes can be gradual.

As cataracts become more advanced, vision becomes ‘foggy’, less detail is seen, reading can be slower, television isn’t perfectly clear and driving becomes difficult when driving into the sun. At this stage, new spectacles will not restore ‘normal’ vision and often surgery is required.

Can cataracts be corrected?

Usually, the answer is yes. Corrective surgery removes the cataract (the cloudy lens), and an artificial lens (intra-ocular lens) is put in its place. This procedure takes up to half an hour and you are back at home a few hours later.

Eye drops are required for a month to ensure your eye doesn’t become infected, and usually, your glasses need to be updated after this.

Can everyone have surgery?

Most people with cataracts will benefit from surgery. Your overall health and any other eye conditions you may have will be considered before a decision is made to operate. Your optometrist will refer you to an ophthalmologist (eye doctor) to confirm that you will benefit from having your cataracts removed.

As we get older many aspects of our vision change. So, it is important to make regular visits to your Optometrist to monitor your vision.

Some Suggestions

  • Regular eye examinations will help you make the most of your vision
  • Continue to enjoy reading and the like – avoiding close work will not ‘save’ your eyes
  • Have good lighting when doing close work, preferably with a reflector lamp to illuminate your task
  • When outdoors, wear a hat with a brim to reduce unwanted glare from the sky
  • Sunglasses may be very helpful in bright conditions
  • Ensure you have an adequate diet with plenty of fresh fruit and vegetables
  • Regular medical examinations are essential to ensure that your health is normal

Cataracts are more likely to develop as we get older. For many people, there is only a mild loss of vision.
