CATARACTS - What you should know




A cataract is a painless clouding of the clear lens of the eye, 
normally caused by ageing.

Cataracts
 
It causes problems to vision, which is often described by those with cataracts as being 'foggy' or 'frosty'. Surgery to remove the lens is the most common form of treatment. Left untreated cataracts can lead to blindness.

There are three types of cataracts: 


1) Nuclear cataracts: located in the centre of the lens. 

2) Cortical cataracts: start at the outer edges of the lens and extend to the centre.

3) Subcapsular cataracts: affect the back of the lens.
