Multifocal intraocular lens implantation is now widely applied for the treatment of cataracts. As one of its advantages, the diffractive intraocular lens provides good far and near vision for the patients. Such lenses are usually designed e.g. using Binary 2 surfaces in Zemax OpticStudio®. In this example, we demonstrate how to import the initial designs into VirtualLab Fusion, and model the lens system with the actual binary structures taken into account. The performance of the diffractive lens is further investigated by varying the height of binary structures.
