To compare the postoperative quality of vision between different bilateral placements of near segments of rotationally asymmetric refractive multifocal intraocular lenses (IOLs) and to determine how this affects visual performance.SettingCathedral Eye Clinic, Belfast, Northern Ireland, United Kingdom.DesignRetrospective comparative case series.MethodsThe study enrolled consecutive patients having refractive lens exchange and implantation of rotationally asymmetric multifocal IOLs. Group 1 received bilateral SBL-3 IOLs and Group 2 received bilateral Lentis Mplus LS-312 MF30 IOLs, with the near segments placed inferonasally in each group. Group 3 received a Lentis Mplus LS-312 MF20 IOL in the dominant eye with the near segment positioned superotemporal and a Lenstec SBL-3 IOL positioned inferonasally in the fellow eye. Binocular uncorrected (UDVA) and corrected distance visual acuities, binocular uncorrected near (UNVA) and intermediate (UIVA) visual acuities, binocular distance-corrected near and intermediate visual acuities, and quality of vision were evaluated over 3 months postoperatively.ResultsThe study enrolled 180 patients (360 eyes). There was no significant difference between the groups in binocular UDVA, UIVA, and UNVA; however, there was a significant difference between the groups in quality of vision (P ≤ .001). Group 3 had significantly better overall quality of vision.ConclusionWhen implanting rotationally asymmetric multifocal IOLs, a combination of superotemporal placement of the near segment (+2.00 diopter [D] addition [add]) in the dominant eye with inferonasal placement of the near segment (+3.00 D add) in the fellow eye yielded consistent, high overall quality of vision and uncorrected visual acuity.Financial DisclosureNone of the authors has a financial or proprietary interest in any material or method mentioned.
