Visual outcomes and patient satisfaction 3 and 12 months after implantation of a refractive rotationally asymmetric multifocal intraocular lens

PURPOSE: To assess the 3-month and 12-month postoperative visual performance and subjective patient satisfaction after refractive lens exchange (RLE) with implantation of a rotationally asymmetric multifocal intraocular lens (IOL). SETTING: Cathedral Eye Clinic, Belfast, United Kingdom. DESIGN: Prospective case series. METHODS: The refraction, uncorrected (UDVA) and corrected distance visual acuities, uncorrected intermediate (UIVA) and near (UNVA) visual acuities, distance-corrected intermediate and near visual acuities, and a quality of vision (QoV) questionnaire were evaluated 3 months and 12 months after implantation of an SBL-3 IOL. RESULTS: The study enrolled 100 eyes of 50 patients. The mean monocular UDVA was -0.02 logarithm of minimum angle of resolution (logMAR) ± 0.12 (SD) 3 months postoperatively and -0.01 ± 0.10 logMAR at 12 months (P = .393). The mean monocular UIVA was 0.39 ± 0.11 logMAR and 0.41 ± 0.12 logMAR, respectively (P = .06). The mean monocular UNVA was 0.12 ± 0.13 logMAR and 0.14 ± 0.12 logMAR, respectively (P = .077). The mean QoV score was 8.26 ± 1.16 at 3 months with a significant improvement at 12 months, at which time the mean QoV score was 8.84 ± 1.08 (P ≤ .001). CONCLUSIONS: This asymmetric multifocal IOL provided excellent unaided vision with no significant difference in near, intermediate, and distance vision 3 months and 12 months postoperatively. However, there was a significant improvement in subjective outcomes at the second postoperative assessment, during which patients reported a significantly better QoV score and less blurred vision.
