摘　　要：针对目前临床上常用的ＳＲＫⅡ公式在计算人工晶体屈光度时的局限性，对４１５只后房型人工晶体眼的角膜屈光力、眼轴长度和正视化人工晶体屈光度进行回归分析后，设计出一种不同于传统的线性回归公式的曲线回归公式——二元三次计算公式。结果：二元三次回归公式为一单调递增曲线，呈连续分布，不分区间。利用二元三次回归公式计算的总体标准差小于ＳＲＫⅡ公式的总体标准差。Objective:Since some limitaions of SRK Ⅱ formula,the dual cubic curved regressive formula was designed.methods:By means of computer,statistical analysis and regressive treatment of kerato diopter,axial length and emmetropic IOL diopter of 415 pseudophakia was done.Result:The dual cubic regressive formula was a progressively increased curve with continous distribution,and the standard deviation produced by the dual cubic formula was less than the standard deviation produced by SRK Ⅱ formula.conclusion:The dual cubic regressive method could be used to calculate IOL diopter more accurately.
