In Vivo Measurement of Longitudinal Chromatic Aberration in Patients Implanted With Trifocal Diffractive Intraocular Lenses

Multifocal corrections are increasingly used solutions for presbyopia, working by the principle of simultaneous vision (ie, projecting simultaneously focused and defocused images on the retina). These corrections, in the form of intraocular lenses (IOLs) or contact lenses, provide multifocality at the expense of reducing optical quality at all distances. Current multifocal IOLs in the market work on diffractive or refractive principles, including refractive bifocal concentric and angular, diffractive bifocal and trifocal, extended depth of focus, or hybrid designs.1 On-bench evaluations of
