title: [Computer-assisted preliminary determination of the refraction of intraocular lenses].
abstract: Seventy-seven cases with posterior chamber lenses were examined after suture removal. The residual astigmatism measured 1.27 D. The remaining refraction (spheric equivalent) was 1.6 D. The relation in size of the two corresponding retina images (isoiconia) was taken into consideration by prior determination of lens power based on computerized measurement. The computer program was developed by Lepper (Bonn). The method of lens power calculation is described.
