  • ABSTRACT: The apodized diffractive multifocal intraocular lens is one of the intraocular lens types currently available for the correction of presbyopia. The design of apodized diffractive multifocal intraocular lenses improves on the visual outcomes obtained with the full optic diffractive and refractive intraocular lenses. In addition to the visual improvements, apodized diffractive multifocal intraocular lenses, using a combination of diffractive and refractive technologies and gradually decreasing diffractive steps from the center to the periphery of the intraocular lens, reduce or eliminate the visual phenomena produced mainly in night conditions when the pupil size increases
