High-order aberrations with Hydroview H60M and AcrySof MA30BA intraocular lenses

Abstract

To compare differences in high-order aberrations between 2 intraocular lenses (IOLs), the Hydroview H60M (Bausch & Lomb) and AcrySof MA30BA (Alcon). Department of Ophthalmology, Nara Medical University, Nara, Japan. Twenty-four eyes of 14 patients with a Hydroview IOL and 25 eyes of 20 patients with an AcrySof IOL who had uneventful phacoemulsification and a best corrected visual acuity better than 20/16 from 6 to 12 months after surgery were evaluated. High-order aberrations were measured using a Hartmann-Shack aberrometer at 4.0 mm and 6.0 mm wavefront aperture diameters, and IOL tilt and decentration were assessed by Scheimpflug videophotography. There were no differences between the 2 groups in IOL tilt and decentration (P>.05, Mann-Whitney U test). In the cornea, there were no differences between the 2 groups in high-order aberrations at 4.0 mm and 6.0 mm aperture diameters (P>.05, Mann-Whitney U test). In the whole eye, there was a significant difference between Hydroview (mean 0.441 microm +/- 0.147 [SD]) and AcrySof (0.696 +/- 0.287 microm) IOLs in spherical-like aberrations at the 6.0 mm aperture diameter (P =.00008, Mann-Whitney U test); there were no differences between the 2 groups in other aberrations. The type of IOLs influenced spherical-like aberrations. The IOL's shape was a particularly important factor in spherical-like aberrations. The aberrations may affect night driving in certain individuals.
