ACCORDING to Haywards Heath-based Sightsavers, it costs £18 to restore sight to a child suffering from cataracts in Asia, Africa and the Caribbean.

Why, then, do private patients in NHS and private hospitals have to pay between £1,300 and £1,800 in Mid Sussex and elsewhere in the south for the same operation?

When cataract operations overseas cost so little, why is the NHS unable to fund more cataract operations in Britain and so reduce the abnormally long waiting lists? I am aged 80 and have glaucoma and cataracts, although I am not proposing to have an operation.
