Kate,
I am going on Wednesday to have the cataract removed from my right eye.
I have spoken to several people who have had the operation and none of them have had any problems like you seem to have had..
One lady has now got ingrowing eyelashes and will have another operation soon to stop them growing. Nothing wrong with her eyesight
I don't have any difficulty reading or driving. The problem was found by my optician in February when I went for an annual eye test.
