A series of forty eyes received intraocular lenses (IOLs) of power +17, +19, or +21 D after consideration of computer calculation based upon data of corneal curvature, axial length, and anterior chamber depth using the formula of R. D. Binkhorst. Results were compared with those of a control group of ninety eyes which were given IOLs of standard +19 D power. No difference was found between the resulting visual acuities or range of postoperative refractions. The preoperative refraction was found to offer no guide to the selection of IOL power. The results were analysed in detail and it was found that the computer prediction of postoperative refraction for the IOLs implanted was of a high level of accuracy. This suggests that improved clinical results are to be expected from a close adherence to the IOL power calculated by a system which has been tested for accuracy and reliability. The cautious minor adjustment of IOL power as in the protocol of this study does not influence the outcome.
根据R.D.宾克霍斯特公式，基于角膜曲率、眼轴长度和前房深度数据进行计算机计算后，为40只眼睛植入了屈光度为+17、+19或+21 D的人工晶状体（IOL）。将结果与90只接受标准+19 D屈光度人工晶状体的对照组眼睛进行比较。结果发现，最终视力或术后屈光范围没有差异。术前屈光情况对人工晶状体屈光度的选择没有指导作用。对结果进行了详细分析，发现所植入人工晶状体术后屈光的计算机预测具有很高的准确性。这表明，严格按照经过准确性和可靠性测试的系统计算的人工晶状体屈光度，有望获得更好的临床效果。本研究方案中对人工晶状体屈光度进行的谨慎微调不会影响结果。
