Abstract

The surfaces and refractive index of crystalline lens play an important role in the optical performance of human eye. On the basis of two eye models, which are widely applied at present, the effect of lens surfaces and its refractive index distribution on optical imaging is analyzed with the optical design software ZEMAX (Zemax Development Co., San Diego, USA). The result shows that good image quality can be provided by the aspheric lens surfaces or (and) the gradient-index (GRIN) distribution. It has great potential in the design of intraocular lens (IOL). The eye models with an intraocular implantation are presented.
