Geometric-phase intraocular lenses with multifocality
Light: Science & Applications, 2022 Multifocal and extended depth-of-focus intraocular lenses (IOLs) embedding μm-thin geometric phase (GP) layers are demonstrated. GP-IOLs will alleviate blurred vision and photic phenomena of conventional presbyopia-correction IOLs.
