ABSTRACT
PurposeTo demonstrate the results of the ray tracing-type aberrometer in measuring spherical aberration (SA) in pseudophakic eyes with monofocal intraocular lens (IOL), aspheric monofocal IOL, or aspheric diffractive multifocal IOL.MethodsTotal, corneal, and internal SA were measured using iTrace at a 6-mm pupil size in 27 eyes of 27 patients implanted with a monofocal spherical IOL (group 1: Natural, SN60AT), 30 eyes of 30 patients implanted with a monofocal aspheric IOL (group 2: IQ, SN60WF), and 30 eyes of 30 patients implanted with a multifocal aspheric IOL (group 3: ReSTOR, SN6AD1) at 3 months after cataract surgery. We compared the internal SAs of these IOLs in pupil sizes of 3, 4, 5, and 6 mm.ResultsThere were no demographic statistically significant differences among the groups. The internal SA of group 1 had a positive value. The internal SA of group 2 was −0.175±0.135 μm in 5-mm pupils and −0.227±0.253 μm in 6-mm pupils. The internal SA of group 3 was −0.072±0.128 μm in 5-mm pupils and −0.173±0.231 μm in 6-mm pupils.ConclusionMeasuring internal SA with iTrace yields relatively accurate results in all types of IOLs with adequate pupil sizes.
