kat-uh-rakt: A clouding of the crystaline lens. It has the effect of looking through a dirty window i.e. reducing the quaility of vision.
Other effects include:
» Halo’s around lights˙
» Glare in sunlight
» Increase in short sightedness / decrease in long sightedness.
» Changes in colour vision
Cataracts progress at various speeds depending on the cause and type. When a cataract begins to impede your everyday lifestyle, it can be removed and replaced with a silicon intra-ocular lens. This is a relatively straight forward procedure with a high success rate.
CAUSES OF CATARACTS
Age related changes are the main cause of cataracts but they can also occur at any age due to:
» A serious injury to the eye
» Mineral deficiencies
» Secondary to diabetes
» The side effect of certain medication
» Smoking
» UV light
» Congenital causes
A regular eye test can help by monitoring the effect a cataract has on your vision. Discuss any questions you have with your Optometrist who will refer you to an Ophthalmologist for further management at the appropriate time.
