摘要：

Customized hybrid diffractive-refractive intraocular lens (IOL) has been designed based oil an individual pseudophakic eye model constructed with the measured corneal topography data and the eye's axial lengths. The detailed designing and optimizing procedure is given. It is Found that an eye with achromatic customized IOL Would achieve super modulation transfer function (MTF) in both the scotopic and photopic conditions. The variation of MTF as colors is negligible, the chromatic focus shift is no more than 0.1 D, and the depth Of focus is 3.0 D with quite high MTF. The achromatic Customized IOL provides excellent visual performance for cataract patients. Moreover, individual pseudophakic eye model can be an effective tool for evaluating the optical performance of pseudophakic eye and the influence of clinical surgery deviation.
