为了矫正老视眼，使其达到在连续范围内清晰视物的目标，探索性地将具有大焦深成像性能的光剑元件(LSOE)作为人工晶体(IOL)引入人眼模型中，运用Matlab 数值模拟的方法，模拟了0~4D 物距内视网膜上的成像效果。同时从E 图、调制传递函数(MTF)曲线和斯特列尔比率这三个角度，将该人工晶体的成像效果与老花镜和反向轴棱镜进行对比分析。结果显示，带有光剑人工晶体的人眼模型基本实现了阅读距离(25 cm)至无穷远处的清晰连续成像，在成像质量上占有优势，并且具有大焦深效果受瞳孔缩放影响较小的突出特点。

In order to get continuous and clear vision over a long distance for the presbyopic eyes, an intraocular lens (IOL) is introduced into the human eye model, and the IOL is designed according to the principle of light sword optical element (LSOE). Based on the method of numerical simulation in Matlab, the retina imaging effect is analysed in terms of E figure, modulation transfer function (MTF) curve and the Strehl ratio under the object distance of 0~4D. The LSOE-based intraocular lens is compared with traditional reading glass and axicon, depending on the quality of compensation. The results show that the LSOE-based IOL achieves clear continuous imaging from reading distance (25 cm) to infinity. It also has an advantage on the imaging quality. And the impact caused by the change of pupil diameter is lower than other elements.
