Chang says that for any moving optic, the resulting amount of accommodative shift is proportional to the dioptric power of the IOL.

That may change in the next year, as the clinical investigators and company researchers at Visiogen are readying their Phase III data for the Synchrony dual-optic accommodating IOL for submission to the Food and Drug Administration.His experience is both encouraging and enlightening.The dual optic accommodating Synchrony IOL (Abbott Medical Optics, AMO, Santa Ana, Calif.) gives the patient the ability to have a full range of vision (distance, intermediate, and near) with high quality of vision.Ray-tracing analysis using optical modeling software (ZEMAXTM, Focus Software Inc., Tucson, Ariz) in a theoretical model eye was used to analyze lens configurations to optimize the accommodative and magnification effects of axial lens displacement.Finite-element modelling using a commercially available PC-based software package (COSMOS Design STAR) was applied to design the biomechanical parameters of the inter-optic articulations and optics.A dual-optic design linked by spring haptics increases the accommodative effect of axial optic displacement with minimal magnification effect and has promise for improving the performance of accommodative intraocular lenses.
