title: [Refraction after cataract surgery with posterior chamber lenses].
abstract: In an attempt to determine the accuracy of ultrasound biometry, the spherical equivalent of the refraction obtained after ECCE and implantation of a posterior chamber IOL in 1663 patients was compared to the desired refraction determined prior to surgery. Follow up time was 21 months on the average. In only 7.4% of the eyes was the exact predetermined value obtained. In 44.3% it differed toward plus and in 46.6% toward minus. The predetermined value +/- 1 dpt was obtained in 63.8% and +/- 2 dpt in 88.3% of the cases. In 11.7% of the eyes, the desired value was missed by more than +/- 2 dpt.
