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.
