Inside your eye you have a lens that sits just behind the iris (coloured part). As a child this lens is usually perfectly clear and lets light travel through it. With time this lens stops being clear and begins to get a little hazy, cloudy and/or yellowed. This usually happens very gradually over many years. Eventually this coudyness can build up enough to affect your vision and this is when it becomes a cataract.
Every person will get cataracts if they live long enough but some things like certain medications (eg steroids), UV exposure, smoking, and diabetes can make then develop early.
We have several specialised pieces of equipment to monitor your cataracts as they progress. If your cataracts become severe enough, then we can arrange a referral to an eye surgeon (ophthalmologist) who can remove the old cloudy lens and replace it with a new clear plastic one.
