What are the different multifocal lenses now available?
There are two different types of multifocal lenses currently available: the diffractive multifocal IOL (e.g. ReSTOR® lens by Alcon Laboratories) and the refractive multifocal IOL (e.g. ReZOOM® lens by Advanced Medical Optics). Each of these lenses provides both distance and near vision but each has its own set of advantages and disadvantages.
