Radially segmented apodized diffractive multifocal design for ocular implant

摘要

A radially segmented apodized diffractive multifocal IOL for ocular implant is provided. The ocular implant can comprise a radially segmented apodized diffractive multifocal intraocular lens optic and a number of haptics. The radially segmented apodized diffractive multifocal IOL may pass optical energy in both photopic and mesopic conditions. The radially segmented apodized diffractive multifocal IOL includes a number of radially segmented apodization zones, each radially segmented apodization zones having a unique focal length. The haptics mechanically couple to the apodized diffractive multifocal IOL optic in order to position and secure the apodized diffractive multifocal IOL within the eye. The radially segmented apodized diffractive multifocal IOL may include both a diffractive region and a refractive region.
