Cataract is a clouding of the lens of the eye which occurs with ageing; it is usally treated with an operation.  Cataract can cause visual problems including difficulty reading.  Some elderly patients develop similar visual problems because of the onset of dementia.  It may be difficult to distinguish visual complaints due to age related eye changes, from visual complaints due to early dementia, particularly as dementia testing is not routine in eye clinics.  Patients whose visual symptons are predominantly due to dementia are likely to have persistent visual symptoms following cataract surgery.

This study will assess patients from the cataract clinic and follow them up for 1 year in order to see if their symptoms are due to dementia and not due to cataract.
