A prospective series of 25 eyes received an intraocular lens (IOL) of power calculated for planned ametropia, by means of the formulae of R. D. Binkhorst, from data of axial length, corneal curvature, and postoperative anterior chamber depth. All the postoperative refractions were within the +/- 2 D range from the predicted refraction, confirming the clinical value of such calculation. A retrospective study of 100 eyes which had received a +19 D power Binkhorst IOL showed a wide range of change in refraction extending up to the +/- 6 D range, indicating that a 'standard' power IOL cannot be relied upon to reproduce the preoperative refraction. Calculation of IOL power from biometric data is essential when controlled postoperative ametropia is required.
对25只眼进行前瞻性研究，根据轴向长度、角膜曲率及术后前房深度的数据，采用R.D.宾克霍斯特公式计算计划屈光不正所需的人工晶状体（IOL）度数。所有术后验光结果均在预测屈光度的±2D范围内，证实了这种计算方法的临床价值。对100只植入+19D屈光度宾克霍斯特IOL的眼睛进行回顾性研究，结果显示屈光变化范围很大，可达±6D，这表明不能依靠“标准”屈光度的IOL来重现术前屈光度。当需要控制术后屈光不正时，根据生物测量数据计算IOL度数至关重要。
