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.
Cathedral Eye Clinic, Belfast, Northern Ireland, United Kingdom.
Retrospective comparative case series.
The 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.
The 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.
When 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.

回顾性比较病例系列。
该研究纳入了连续进行屈光性晶状体置换并植入旋转不对称多焦点IOL的患者。第1组接受双侧SBL-3 IOL，第2组接受双侧Lentis Mplus LS-312 MF30 IOL，每组的近节段均放置在下鼻侧。第3组在主眼植入Lentis Mplus LS-312 MF20 IOL，近节段位于颞上方，在对侧眼植入Lenstec SBL-3 IOL，近节段位于下鼻侧。在术后3个月评估双眼未矫正（UDVA）和矫正远视力、双眼未矫正近（UNVA）和中视力（UIVA）、双眼远矫正近和中视力以及视力质量。
该研究纳入了180例患者（360只眼）。各组之间在双眼UDVA、UIVA和UNVA方面无显著差异；然而，各组之间在视力质量方面存在显著差异（P≤0.001）。第3组的总体视力质量明显更好。
植入旋转不对称多焦点IOL时，主眼近节段颞上方放置（附加+2.00屈光度[D]）与对侧眼近节段下鼻侧放置（附加+3.00 D）相结合，可产生一致的、高总体视力质量和未矫正视力。
