Abstract Details

Purpose:

To evaluate long-term visual performance and satisfaction of patients implanted monocularly with a small aperture intraocular lens (IOL) in their non-dominant eye and an aspheric monofocal lens in their dominant eye.

Setting:

Retrospective, multi-center study

Methods:

Sixty-four patients presenting for cataract surgery, were implanted contralaterally with an IC-8 IOL (AcuFocus), and an aspheric monofocal IOL. IC-8 eyes were targeted for a residual refraction of -0.75 D and fellow monofocal eyes were targeted for plano. Uncorrected (U) distance (D), intermediate (I) and near (N) visual acuities (VA), and mean refractive spherical equivalent (MRSE) were evaluated at 1, 3, 6 months, and one long-term visit post-implantation (mean long-term follow-up 31 months (±4.2). Visual acuity is reported in logMAR ± standard deviation. Additionally, satisfaction (Scale: 1=very dissatisfied, 5=very satisfied) and symptoms (Scale: 1=very mild, 5=very severe) were evaluated.

Results:

Long-term mean MRSE was -0.45 ± 0.70 in the IC-8 eyes, and +0.06 D ± 0.48 in the monofocal eyes. The mean binocular UDVA, UIVA and UNVA was 0.00 ± 0.10, 0.06 ± 0.14 and 0.20 ± 0.16 respectively. UCDVA showed statistically significant difference between the long-term visit and the 1 and 6 month exams (p=0.0051 and p=0.0141, respectively). Patients reported low visual symptoms (1.37 ± 1.66 for glare and 1.09 ± 1.56 for halo). Overall satisfaction with vision was 4.2 ± 0.87. No significant differences were seen for MRSE, UCNVA, UCIVA, symptoms or satis-faction at any time point.

Conclusions:

Patients maintained good visual performance over the long-term and reported overall high satisfaction and low visual symptoms after contralateral implantation with an IC-8 IOL and an aspheric monofocal IOL.
