Abstract

Based on the Hwey-Lan Liou eye model and the equivalent rule,crystal lens is replaced with accommodative intraocular lens (AIOL) for imaging at infinite distance. Based on the analysis of imaging quality of human eye, the displacement, medium refractive index, central thickness, structure, aspheric refractive surface of the AIOL are studied with ZEMAX to implement light ray tracing method. Simulation results indicate that the displacement of AIOL has the greatest impact on its tunability; while it is hardly affected by the medium refractive index, central thickness, and structure. The AIOL with aspheric surface has better tunability.

Key words
