Posterior chamber lenses with angled haptics were implanted in one eye of each of 53 patients with senile cataract. Dioptric aniseikonia was calculated between 1 month and 24 months after surgery (with Gruber's and Huber's computer program) on the basis of most recently obtained values (bulb axis length, depth of the anterior chamber, lens thickness, necessary refraction), and compared with subjective measurements taken with the phase difference haploscope. The agreement between the calculated and subjective aniseikonia was greatest when tested in a vertical meridian. However, it was not possible to predict any correlation between dioptric and subjective aniseikonia with confidence. On the basis of the test results it seems justified to aim for a minimal refractive error in the pseudophakic eye of about +/- 0.5 D in patients with hypermetropia or myopia up to 4 D, even if subjective aniseikonias of over 10% can be proved. The latter manifest great meridional differences and hardly interfere with binocular single vision.
对53例老年性白内障患者，每例患者的一只眼睛植入了具有成角度袢的后房型人工晶状体。术后1个月至24个月期间，使用Gruber和Huber计算机程序，根据最近获得的值（眼球轴长、前房深度、晶状体厚度、所需屈光度）计算屈光性像不等，并与使用相差检眼镜进行的主观测量结果进行比较。在垂直子午线上进行测试时，计算得到的像不等与主观像不等之间的一致性最高。然而，无法有把握地预测屈光性像不等与主观像不等之间的任何相关性。根据测试结果，对于远视或近视度数高达4D的患者，即使可以证明主观像不等超过10%，在人工晶状体眼内将屈光不正误差控制在约±0.5D似乎是合理的。后者表现出很大的子午线差异，几乎不影响双眼单视。
