A cataract is a hazy area within the normal transparent lens of the eye. Although cataracts can occur at any age, they are generally part of the normal aging of the eye. Approximately 50% of people over 60 have this condition. It is therefore important not to be alarmed if you are told you have cataracts.
Common symptoms of Cataracts are
Blurry, foggy or misty vision.
Changes in how you see colours
Changes in your spectacle prescription
Increased difficulty with driving at night
Glare in bright light
Decisions about your cataracts.
The effect a cataract has upon your vision will vary according to a number of factors such as
The position of the hazy area within the lens
The size of the hazy area
Your level of vision before the cataract was there
The rate at which your cataract is changing (if at all)
These factors contribute to the decision the Optometrist makes about your cataracts. Changing your spectacle prescription.
It may be the only affect the cataract has (particularly during the early stages) iIs to cause a change in your spectacle, and that with the new prescription you see reasonably well.
Monitoring the Cataract.
We may decide that all we need do is monitor how the cataract is affecting your vision. Some cataracts do develop quickly, while others remain the same for much longer periods of time. In some cases we may recommend that we see you more frequently than we have done in the past.
Referring you to an eye specialist
If the cataracts are causing a significant problem to your vision and/or way of life, we may feel it appropriate to recommend referral to an eye specialist. The specialist will assess the cataract with a view to removing it in order to improve your standard of vision. The surgery to remove a cataract is now relatively quick and simple and does not normally require an overnight stay in hospital.
