Abstract Details

Purpose:

To compare 6-month uncorrected and target-corrected outcomes of patients implanted with a small aperture (IC-8) intraocular lens (IOL) in the non-dominant eye and an aspheric monofocal IOL in the dominant eye.

Setting:

Augen-Zentrum-Nordwest, Ahaus, Germany

Methods:

Eleven patients presenting for cataract surgery, were monocularly implanted with an IC-8 IOL (AcuFocus), and an aspheric monofocal IOL in the fellow eye. Monofocal eyes were targeted for plano, while IC-8 eyes were targeted for -0.75 D post-op refraction. Uncorrected (U) and target-corrected (TC) distance (D), intermediate (I) and near (N) visual acuities (VA), and mean refractive spherical equivalent (MRSE) were evaluated at 6 months post-implantation. Mean acuity is reported in logMAR and snellen equivalent.

Results:

Mean uncorrected MRSE was �.10 D � 0.68 in the IC-8 eye and �.60 D � 0.71 in the monofocal eye. Target-corrected MRSE was -0.75 D in the IC-8 eye and plano in the monofocal eye. The mean binocular UDVA, UIVA and UNVA following monocular IC-8 implantation was 0.01 � 0.10 (6/6), 0.12 � 0.20 (6/7.5) and 0.28 � 0.17 (6/12) respectively and improved with target-correction to -0.09 � 0.11 (6/4.8), 0.05 � 0.13 (6/6) and 0.16 � 0.14 (6/9) for TCDVA, TCIVA and TCNVA respectively.

Conclusions:

With a target correction of -0.75D in the IC-8 eye, near and intermediate visual acuities improve while excellent distance visual acuity is maintained. Both uncorrected and target-corrected visual acuities show patients achieve good for near, intermediate and distance vision performance despite the differences in refractive error.
