Abstract
In this paper, optimum design of three classic model have been proposed, for refractive multifocal intraocular lenses (singlet, doublet, triplet-MIOLs) implanted within human eye (Liou & Brennan model). The analysis were carried out with ZEMAX-EE optical software through the polychromatic functions; MTF, PSF, spot diagram and (longitudinal-, Sphero-) chromatic aberration in addition to comparison with healthy eye. Due to good biocompatibility, AR40N Allergan and AcrySof SA60AT were used to design refractive MIOLs in unique and / or dual combination. Correction of the spherical aberration and longitudinal chromatic aberration (LCA) within 5° of visual field and 4 mm of pupil diameter were performed over the spectral region (455-655 nm). Result indicate that for all MIOLs proposed design (pseudophakic eye) sharp vision was achieved for a set of distances within range (25-108cm) but still much less than in healthy eye and pseudophakic eye with triplet-MIOLs implanted was the best model.
