[A new program for calculating intraocular lenses].
A principally new programme is described which overcomes the disadvantages of the usual calculation methods. It is based on the application of each surface of the optical system. The point for the anterior chamber lens is chosen in dependence on the anterior chamber depth; for the posterior chamber lens on the posterior surface of the eye lens. The programme is able to calculate 12 different cases. In each case calculations are made for intraocular lens power, aniseikonia and anisometropia. The calculations are made for possible emmetropia as well as for intended myopia or hypermetropia corresponding to the other eye. The programme can also be used to estimate the effect of mistakes made by measuring the single parameters, for instance: refraction, corneal curvature, eye length, anterior chamber depth. Compared to the SRK II-equation the results of the new programme are much more precise.
