Lens manufacturers do not usually supply information about the central thickness of an intraocular lens optic. This paper describes a method to calculate the central lens thickness from variables normally supplied by the manufacturer, i.e., the total lens power in situ, the edge thickness, the optic diameter, and some knowledge of the optic architecture. The formulas are universal and valid for any lens, regardless of lens design and material. There is a correlation between calculated values of optic thickness and values supplied by manufacturers. Individually estimated lens thickness may increase the accuracy of intraocular lens power calculation, pseudophakic anterior chamber depth estimation, and pseudophakic axial length calculation.
晶状体制造商通常不会提供人工晶状体光学部中心厚度的信息。本文描述了一种根据制造商通常提供的变量来计算晶状体中心厚度的方法，即原位总晶状体屈光力、边缘厚度、光学部直径以及一些光学部结构知识。这些公式具有通用性，适用于任何晶状体，无论其设计和材料如何。光学部厚度的计算值与制造商提供的值之间存在相关性。单独估计晶状体厚度可能会提高人工晶状体屈光力计算、人工晶状体眼的前房深度估计以及人工晶状体眼的眼轴长度计算的准确性。
