PURPOSE: To evaluate visual outcomes with particular attention to visual acuity of a segmental refractive multifocal intraocular lens, the ACUNEX VarioMax (Teleon Surgical).
METHODS: This prospective, non-randomized, non-comparative study was conducted at the Department of Ophthalmology, University Hospital, Goethe University, Frankfurt, Germany. Thirty-four eyes (17 patients) were included. Inclusion criteria were bilateral cataract, age older than 30 years, and predicted corneal astigmatism ≤0.75 diopters (D) postoperatively. Exclusion criteria were prior ocular surgeries, amblyopia, or potential postoperative corrected distance visual acuity worse than 0.3 logarithm of the minimum angle of resolution (logMAR). Uncorrected visual acuities for distance, intermediate, and near and distance-corrected visual acuities at 4 m, 80 cm and 40 cm, contrast sensitivity, defocus curve, and questionnaires on optical quality, quality of life, and spectacle independence were assessed after 3 months.
RESULTS: The mean monocular uncorrected distance visual acuity was 0.02 ± 0.09 logMAR at 4 m, uncorrected intermediate visual acuity was 0.15 ± 0.12 logMAR at 80 cm and uncorrected near visual acuity was 0.24 ± 0.10 logMAR at 40 cm. Defocus curve testing showed a distance-corrected binocular visual acuity range between 0.00 and -2.50 D (from -0.06 to 0.12 logMAR). Median contrast sensitivity under photopic and mesopic conditions was 1.48 ± 0.18 and 1.25 ± 0.29 logCS, respectively.
CONCLUSIONS: This segmental multifocal intraocular lens provides good visual acuity at all distances, particularly providing good intermediate visual acuity and depth of focus. It showed good contrast sensitivity and high spectacle independence with a high degree of patient satisfaction.
