title: Regional variation in cataract extraction rates and their relationship with resource supply and need.
abstract: There are large variations in cataract extraction rates between different regions of England, which may indicate differences in the availability of the operation in different parts of the country. Analysis shows that there is a relationship between the availability of ophthalmic beds and operation rates, but it is not possible to determine whether the bed supply determines the operation rate or vice versa.
