Experimental measurement of Longitudinal Chromatic Aberration in patients implanted with trifocal diffractive IOLs, published in JRS

Trifocal diffractive Intraocular Lenses are increasingly popular designs for the correction of Presbyopia. Using a polychromatic Adaptive Optics system we measured chromatic difference of focus at multiple wavelengths (psycophysical and double-pass measurements) and far/intermediate/near foci in 10 patients bilaterally implanted with the FINeVision Trifocal IOL (hydrophilic material) by PhysIOL. Longitudinal Chromatic Aberration was largest for far and close to zero for near vision. Refractive and diffractive effects can be used to modulate chromatic aberration in patients implanted with diffractive IOLs.

The study is the result of collaborative work between VioBio Lab (CSIC) Innova Ocular  and PhysIOL
