With the development of the technology of phacoemulsification and intraocular lens (IOL) implantation, the calculation formula of IOL power has been optimized. The existing formulas are still not accurate enough for some special cases, such as patients with short or long axial length and previous corneal refractive surgery, because the calculation of IOL power is a nonlinear function, and these mathematical formulas based on an optical model can not show the nonlinear relationship well. Therefore, new IOL calculation formulas developed by using an artificial intelligence nonlinear mathematical model have come into being. This review demonstrates the development and application of new IOL calculation formulas, in order to provide guidance for improving the visual quality and clinical application of each calculation method in cataract patients.
随着超声乳化白内障吸除术和人工晶状体（IOL）植入技术的发展，IOL屈光力计算公式得到了优化。对于一些特殊情况，如眼轴短或长的患者以及既往有角膜屈光手术史的患者，现有的公式仍不够准确，因为IOL屈光力的计算是一个非线性函数，而这些基于光学模型的数学公式无法很好地体现这种非线性关系。因此，利用人工智能非线性数学模型开发的新IOL计算公式应运而生。本文综述展示了新IOL计算公式的发展与应用，旨在为提高白内障患者各计算方法的视觉质量及临床应用提供指导。
