Abstract Details

Purpose:

To compare the visual and refractive outcomes of patients who underwent binocular or monocular implantation of asymmetric refractive multifocal intraocular lenses (MF IOLs) with or without a toric component.

Setting:

Minatomirai Eye Clinic, Yokohama, Japan, and Department of Ophthalmology, Keio University School of Medicine, Tokyo, Japan.

Methods:

This retrospective comparative case series included patients who underwent implantation of asymmetric refractive MF IOLs with or without a toric component (LS-313 MF 30, LM group; LS-313 MF 30T, LMT group, Oculentis GmbH, Germany). The LM group included 108 eyes (64 patients) and the LMT group 81 eyes (49 patients). The main outcome measures were corneal astigmatism, subjective refraction, uncorrected distance visual acuities (UDVA), uncorrected near VA (UNVA), and the need for an additional refractive procedure and Nd:YAG laser posterior capsulotomy. The preoperative and 1-year postoperative data were evaluated.

Results:

Preoperative corneal astigmatism (mean ± standard deviation) was significantly (P<0.001) higher in the LMT group than the LM group (1.58 ± 0.59 diopters [D] versus 0.63 ± 0.32 D, respectively). The mean values in the LM and LMT groups, respectively, were corneal astigmatism, 0.63 and 1.58 D; subjective spherical equivalent, 0.26 and 0.12 D; refractive astigmatism, 0.27 and 0.38 D; UDVA, -0.05 and -0.03 logarithm of the minimum angle of resolution (logMAR); and UNVA, 0.25 and 0.18 logMAR. Refractive and visual outcomes and enhancement and posterior capsulotomy rates did not differ significantly (P>0.05) at 1 year except corneal astigmatism (P<0.001).

Conclusions:

Asymmetric refractive MF IOLs provided excellent visual and refractive outcomes with or without a toric component 1 year after implantation.
