In Vitro Aberrometric Assessment of a Multifocal Intraocular Lens and Two Extended Depth of Focus IOLs

Purpose. to analyze the in vitro aberrometric pattern of a refractive iol and two extended depth of focus iols. methods. a special optical bench with a shack-hartmann wavefront sensor (sh) was designed for the measurement. three presbyopia correction iols were analyzed: mini well (mw),tecnis symfony zxr00 (sym),and lentis mplus x ls-313 mf30 (mp). three different pupil sizes were used for the comparison: 3,4,and 4.7 mm. results. mw generated negative primary and positive secondary spherical aberrations (sa) for the apertures of 3 mm (-0.13 and +0.12 μm),4 mm (-0.12 and +0.08 μm),and 4.7 mm (-0.11 and +0.08 μm),while the sym only generated negative primary sa for 4 and 4.7 mm apertures (-0.12 μm and-0.20 μm,resp.). the mp induced coma and trefoil for all pupils and showed significant hoas for apertures of 4 and 4.7 mm. conclusions. in an optical bench,the mw induces negative primary and positive secondary sa for all pupils. the sym aberrations seem to be pupil dependent; it does not produce negative primary sa for 3 mm but increases for higher pupils. meanwhile,the hoas for the mw and sym were not significant. the mp showed in all cases the highest hoas. © 2017 vicente j. camps et al.
