A new and complete methodology of monofocal intraocular lens (IOL) design is presented aiming at isoplanatism, i.e. IOLs that provide the eye with optimized optical quality over a wide field of view (typically in a range of ten degrees). The methodology uses a merit function considering dimensional and biomechanical constraints, and a geometrical optical quality metric that is evaluated simultaneously at different field angles. As an example, we present new isoplanatic designs based on different commercial IOL platforms. Aspheric isoplanatic designs improve peripheral quality over current aspheric IOLs. Also, isoplanatic designs provide more stable optical quality across the field and across pupil diameter.
提出了一种全新且完整的单焦点人工晶状体（IOL）设计方法，旨在实现等视平性，即能在宽视场（通常在10度范围内）为眼睛提供优化光学质量的人工晶状体。该方法使用一个考虑尺寸和生物力学约束的优值函数，以及一个在不同视场角同时评估的几何光学质量指标。例如，我们展示了基于不同商业IOL平台的新等视平性设计。非球面等视平性设计比当前的非球面IOL能改善周边质量。此外，等视平性设计在整个视场和整个瞳孔直径范围内提供更稳定的光学质量。
