Abstract

In this study, an in vitro comparison of the optical performances of three models (spherical, aberration-neutral, and aberration-correcting) of monofocal intraocular lenses (IOLs) is proposed. A comprehensive model is employed, encompassing a wide range of corneal models and aperture sizes, reflecting the high variability of corneal spherical aberrations (SA) and pupil sizes in both normal and postoperative refractive corneal surgery populations. Analysis of average through-focus modulation transfer function (MTF) curves reveals significant differences in optical performance attributable to pupil size and corneal SA. These differences depend on the IOL model and affects MTFmax (representing contrast at best focus), depth of focus, refractive error tolerance, and the effective power of the lens.

摘要

在本研究中，提出了对三种单焦点人工晶状体（IOL）模型（球面、像差中性和像差校正）的光学性能进行体外比较。采用了一个综合模型，该模型涵盖了广泛的角膜模型和孔径尺寸，反映了正常和屈光性角膜手术后人群中角膜球差（SA）和瞳孔大小的高度变异性。对平均全聚焦调制传递函数（MTF）曲线的分析揭示了由于瞳孔大小和角膜SA导致的光学性能的显著差异。这些差异取决于IOL模型，并影响MTFmax（代表最佳聚焦时的对比度）、焦深、屈光不正耐受性和晶状体的有效屈光力。
