title: Anisophoria and aniseikonia. Part II. The management of optical anisophoria.
abstract: Part I of this publication dealt with the simultaneous occurrence of aniseikonia and optical anisophoria when anisometropic spectacles are worn. Part II deals with the correction and management of spectacle-induced anisophoria. It presents simple formulas for calculating the constants of an iseikonic correction that circumvent much of the trial and error inherent in the older methods. It shows how such iseikonic lenses rather than prisms can be used to correct a large portion of optical anisophoria and how such corrections can improve binocular visual performance. It also discusses dynamic phorometry and some new methods for measuring induced anisophoria. The essential message of Parts I and II is that the two effects, aniseikonia and optical anisophoria, should be considered together and not as separate entities.
