title: [Control of refraction in cataract surgery].
abstract: The optical problems associated with cataract surgery are reviewed and methods to control the refractive state of the eye after the operation are presented. The clinical benefit of a calculation of intraocular lens (IOL) power from measurements of corneal curvature and eye length is demonstrated in a series of operated patients from two Danish eye departments. It is concluded, that the postoperative refraction can be controlled with a reasonable accuracy. Large and unexpected deviations in the postoperative refraction are avoided in this way, and in a number of cases it is possible to reduce the need for spectacles after the operation.
