[Functional aniseikonia following implantation of a posterior chamber lens in the early postoperative phase].
Three to five days after unilateral posterior chamber lens implantation in 25 patients iso-iconia was measured with the Aulhorn phase difference projection haploscope. The results were compared with measurements obtained with a computerized calculation program. The average aniseikonia values (4.1%) were in good agreement with the pre-calculated computer data (3.2%). Causes of the wideranging individual differences are discussed: postoperative astigmatism; anterior chamber depth; measuring errors; reliability of the information provided by the patients. This investigation confirms that aniseikonia after implantation of a posterior chamber lens is less pronounced than when cataract spectacles or contact lenses are used.
