Abstract

Abstract: : Purpose:The purpose of this study is to design an accommodative intraocular lens. Methods:The IOL consists of six or eight symmetrically arranged eccentric "Gaussian lenses", which are mounted on an elastic thin wire frame. These Gaussian lenses are almost overlapped but just about 0.5 mm off center. Each Gaussian lens can be pushed toward center when the ciliary muscle squeezes the outer diameter of the elastic wire frame. When the Gaussian lenses are pushed more overlap, the focusing power of the combined lens will be increased. Results:According to the calculation, when the outer diameter of the combined lens changes 0.5 mm, the focusing power of the combined IOL will be changed from 20 diopters to 30 diopters. Conclusion:Our designated intraocular lens could reach the same accommodative power as the real human lens.
