采用Binkhorst II、Sanders/ Retzlaff/Kraff（SRK I（TM）、SRK II（TM）、SRK/T（TM）、Holladay和Olsen公式）对822例人工晶状体植入进行了多中心研究，评价了人工透镜（IOL）屈光度计算的准确性。除了第一个之外，所有这些都是通过计算每种透镜类型的SRK A常数、Holladay外科医生因子和Olsen人工晶状体前房深度（ACD）进行回顾性优化的。Olsen公式的ACD预测是基于先前描述的包括术前ACD、角膜高度、眼轴长度和透镜厚度的回归公式。在光学IOL屈光度计算公式中，Binkhorst公式的预测误差最大，Olsen公式的预测误差最小，比SRK/T和Holladay公式更准确（P
The accuracy of intraocular lens (IOL) power calculation was evaluated in a multicenter study of 822 IOL implantations using the Binkhorst II, Sanders/ Retzlaff/Kraff (SRK I (TM), SRK II (TM), SRK/T (TM), Holladay, and Olsen formulas. All but the first of these were optimized in retrospect with calculation of the SRK A-constant, the Holladay surgeon factor, and the Olsen pseudophakic anterior chamber depth (ACD) for each lens style. The ACD prediction of the Olsen formula was based on a previously described regression formula incorporating preoperative ACD, corneal height, axial length, and lens thickness, Among the optical IOL power calculation formulas, the highest IOL power prediction error was found with Binkhorst's and the lowest with Olsen's, which was more accurate than the SRK/T and the Holladay formulas (P
