    • A system for providing an intraocular lens includes a processor and a computer readable memory. The computer readable memory is configured to communicate with the processor, the memory having stored therein at least one of: one or more ocular dimensions, and at least one predetermined refractive outcome. The memory further includes a sequence of instructions which, when executed by the processor, cause the processor to select an intraocular lens, select a power of an intraocular lens, or provide an intraocular lens. The sequence of instructions includes determining one or more dimensions of an eye. The instructions also include calculating, based on a mathematical relationship, a distance from an apex of a cornea of the eye to an apex or plane of the intraocular lens after insertion into the eye. The instructions further calculating an optical power of the intraocular lens suitable for providing a predetermined refractive outcome. The mathematical relationship includes an axial length of the eye, an anterior chamber depth of the natural crystalline lens, and a corneal radius of the eye, but is independent of a thickness of the natural crystalline lens.
    • 用于提供眼内透镜的系统包括处理器和计算机可读存储器。 计算机可读存储器被配置为与处理器通信,其中存储有存储器中的至少一个:一个或多个眼睛尺寸和至少一个预定折射结果。 所述存储器还包括指令序列,当由所述处理器执行时,使所述处理器选择人工晶状体,选择人工晶状体的能量或提供眼内透镜。 指令序列包括确定眼睛的一个或多个维度。 说明书还包括基于数学关系计算在插入眼睛之后从眼睛的角膜的顶点到眼内透镜的顶点或平面的距离。 所述指令还计算适于提供预定屈光结果的眼内透镜的光焦度。 数学关系包括眼睛的轴向长度,天然晶状体的前房深度和眼睛的角膜半径,但是与天然晶状体的厚度无关。
