Abstract：
: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.
