Aspheric aberration-correcting IOL leads to enhanced visual acuity, depth of focus, contrast sensitivity

LISBON, Portugal — Implantation of a new aspheric IOL that allows individual correction of corneal spherical aberration showed superior results when compared with an identical design aspheric aberration-neutral IOL in a study.
The results of 92 cataract patients implanted with the Individua-aA IOL (HumanOptics) were compared with those of a control group of 41 patients implanted with the Aspira-aA (HumanOptics). The two groups had comparable basic characteristics, with a wide variability of spherical aberration between 0.1 µm and 0.7 µm but similar mean values
