Purpose

To compare ocular higher order aberrations (HOAs) and visual outcomes according to the add power of the near segment in eyes with rotationally asymmetric multifocal intraocular lenses (mIOLs).

Setting

This retrospective study was performed in pseudophakic eyes with implantation of rotationally asymmetric mIOLs (LS-313 MF20 [Group A, n=41 or MF30 [Group B, n=43]) with the near segment positioned inferiorly.

Methods

From the review of medical records, corneal and ocular HoAs at 4.0 mm of measuring diameter and visual outcomes such as uncorrected distance (UDVA), intermediate (UIVA, 66cm), near visual acuity (UNVA, 33cm), contrast sensitivity (CS), were compared between two groups both before cataract surgery and at two months postoperatively.

Results

Preoperative corneal HoAs such as vertical coma, horizontal coma, and spherical aberration (SA) showed no difference between two groups (all P>0.05). Change of vertical coma, total coma and total trefoil were higher in group B than group A (P=0.015, 0.039, and 0016, respectively). Change of horizontal coma and SA was found no differences between two groups. UDVA and CS showed no difference between two groups (all P>0.05). UIVA in group A was better than that in group B (P<0.001) and UNVA in group B was better than that in group B (P<0.001).

Conclusions

Although the add power of the near segment positioned inferiorly in rotationally asymmetric multifocal IOLs produce HoAs, it might not affect to visual outcomes.
