AcuFocus IC-8 intraocular lens for myopic patients with cataract: a retrospective study

Purpose: To retrospectively review visual outcomes of patients with myopia who were implanted with the IC-8 intraocular lens in the nondominant eye and a monofocal intraocular lens in the dominant eye at a private ophthalmology clinic in Australia. Methods: We retrospectively reviewed medical records of consecutive patients aged ≥18 years who had myopia (-0.25 diopter) in both eyes and astigmatism (-2.50 diopters) in the nondominant eye and underwent bilateral cataract surgery and implantation of the IC-8 intraocular lens in the nondominant eye and a monofocal intraocular lens in the dominant eye between January 2018 and February 2020 at a private ophthalmology clinic in Australia. At 6 months, uncorrected monocular and binocular distance, intermediate, and near visual acuity was assessed. Dysphotopsia symptoms was evaluated with the Quality of Vision questionnaire. Results: Medical records of 15 men and 10 women aged 28 to 79 (mean, 60.8±11.5) years of Chinese (n=16), Caucasians (n=8), and South Asian (n=1) ethnicity were reviewed. The mean spherical equivalent improved from -2.92 to -1.20 diopters in nondominant eyes and from -2.42 to -0.13 diopters in dominant eyes. Binocularly, 92%, 64%, and 100% of patients achieved uncorrected distance, intermediate, and near visual acuity of logMAR 0 or better, logMAR 0 or better, and logMAR 0.20 (N5) or better, respectively. The mean Quality of Vision questionnaire score was 32.1 for frequency, 25.4 for severity, and 23.9 for bothersomeness of dysphotopsia symptoms. The rate of laser capsulotomy was higher in eyes with the IC-8 intraocular lens than eyes with the monofocal intraocular lens (72% vs 48%, p=0.08). Conclusions: The IC-8 intraocular lens can extend the depth of focus and is a good option for patients with myopia. It provides good binocular uncorrected distance, intermediate, and near visual acuity when used in conjunction with a monofocal intraocular lens in the dominant eye. Some patients may have dysphotopsia symptoms, but the symptoms are not frequent, severe, or bothering.
