%X    The purpose of this study is to present the design of a new 43D model eye that is geometrically and optically similar to the Liou and Brennan eye model. A comparison is made between the 43D eye model and the ISO 11979-2, Annex C model eye.     The industry-standard Liou and Brennan eye model [1] was used as the baseline for an average presbyopic eye. The new 43D model eye was designed to be geometrically and optically similar to the Liou-Brennan eye model. Three tests were done to verify the design of the new 43D model eye. First, the total power of the 43D model eye and an ISO 11979-2 eye model were measured and compared to the Liou-Brennan eye model. Second, the spherical aberration (SA) of the 43D model eye and an ISO 11979-2 model eye were also measured. Finally, the expected add power of a simple two zone PMMA bifocal lens was analytically calculated using both model eyes and compared to the Liou-Brennan eye model.     The 43D model eye agrees better with the Liou-Brennan model geometrically and optically than the current ISO 11979-2 model eye.     The new 43 D wetcell is better suited to testing IOL optical performance than the ISO 11979-2 prescribed model eye.[1] Liou H. and Brennan N.A., Anatomically accurate, finite model eye for optical modeling, J.
