Clinical outcomes with distance-dominant multifocal and monofocal intraocular lenses in post-LASIK cataract surgery planned using an intraoperative aberrometer

ImportanceStudies evaluating the clinical benefits of intraoperative aberrometry (IA) in cataract surgery are limited. BackgroundThe study was designed to determine whether IA improved clinical outcomes of post-laser in situ keratomileusis (LASIK) cataract surgery with different intraocular lenses (IOLs) implanted. DesignA retrospective chart review of clinical outcomes from one surgeon at one surgical centre was conducted. It included post-LASIK cataract surgeries where IA was used for the confirmation of IOL power, with either a distant-dominant multifocal IOL or a monofocal IOL implanted. ParticipantsRecords for 44 eyes of 31 patients were analysed. MethodsDifferences in visual acuity (VA) and refractions by lens type were compared, and the effects of IA were evaluated. Main Outcome MeasuresUncorrected distance VA and the percentage of eyes with a spherical equivalent refraction within 0.5D of the intended correction were the primary outcome measures. ResultsThere was no statistically significant difference in the percentage of eyes with uncorrected distance VA of 20/25 or better between IOL groups (P = 0.41). More eyes in the multifocal group had a refraction within 0.50D of intended (P = 0.03). In 39% of cases, the preoperative and IA power calculations suggested the same IOL power. When not equal, the IA results were not significantly more likely to be best' (P = 0.08). Conclusions and RelevanceResults suggest that a history of previous LASIK is not a contraindication to use of distant-dominant multifocal IOLs. IA did not appear to improve clinical outcomes in post-LASIK eyes, although a positive trend was evident.
