Abstract Details

Purpose:

To evaluate the visual performance of patients implanted monocularly with a small aperture hydrophobic intraocular lens (IC-8 IOL).

Setting:

Asian Eye Institute, Philippines

Methods:

A series of nine patients, presenting for cataract surgery, were implanted monocularly with a single-piece hydrophobic acrylic IOL with a centrally located opaque annular mask measuring 3.23mm in total diameter with a 1.36mm central aperture. Uncorrected distance, intermediate and near visual acuities (UDVA, UIVA & UNVA) and depth of focus were evaluated for 12-months after implantation. Mean ± standard deviation visual acuity is reported in logMAR.

Results:

The mean MRSE was -0.13D. The mean monocular UDVA, UIVA and UNVA improved significantly from 0.36 ± 0.14, 0.45 ± 0.18 and 0.61 ± 0.21 at preop to 0.04 ± 0.05 (p < 0.0001), 0.05 ± 0.06 (p < 0.0001) and 0.06 ± 0.09 (p < 0.0001) at 1 month respectively and remained stable until 12 months. At 12 months, 78%, 67% and 89% of patients achieved 20/25 or better in the implant eye at distance, intermediate and near respectively. 100% of eyes maintained 20/40 or better visual acuity over a range of +0.50 D to -1.50 D of defocus.

Conclusions:

Early results demonstrate monocular IC-8 IOL implantation provides a continuous, broad range of vision and excellent acuity across all focal distances.
