Through-Focus Optical Bench Performance of Extended Depth-of-Focus and Bifocal Intraocular Lenses Compared to a Monofocal Lens

New IOL developments are focused on improving both far and intermediate vision while maintaining a functional level of near vision, as well as minimizing photopic phenomena associated with high add multifocal IOLs.1 One example of these new developments is the low add bifocal IOLs (AcrySof SV25T0; Alcon Laboratories, Inc., Fort Worth, TX, and TECNIS ZKB00; Abbott Medical Optics, Inc., Santa Ana, CA) that reduce the distance between the far and near focus generated by the IOL and therefore minimize the size of the associated halo.1,2 Another new technology is the concept of the extended
