Abstract Details


To measure the amount of chromatic aberration of different intraocular lens designs.


AMO Groningen BV, Netherlands


Chromatic aberration was measured in vitro for nine different lens designs. Refractive error was measured in a model eye for five different wavelengths (450, 500, 550, 600, and 650nm). The best focus position was based on maximizing imaging quality (MTF at 50c/mm). Each measurement was performed for two lenses of the same design. Chromatic aberration was expressed refractive error in diopters in the spectacle plane. Results were fitted with a hyperbolic curve (refraction as a function of wavelength; Thibos et. al, 1992).


Over the measured range of wavelength the average chromatic aberration of the different lens designs was 1.47 diopter. The difference between the lens design having the largest amount of chromatic aberration and the lens design having the lowest amount of chromatic aberration was 1.03 diopters. The lens with the lowest amount of measured chromatic aberration shows smaller chromatic aberration than the aphakic eye. This means that the lens corrects corneal chromatic aberration.


Chromatic aberration of IOLs can be measured in a physiologically representative chromatic eye model. Ocular chromatic aberration, measured in the range between 450nm and 650nm, varies by as much as 1 diopter between different IOL designs.
