The ReZoom multifocal intraocular lens: 2-year follow-up.

PURPOSE To evaluate distance, intermediate, and near visual acuity and patient satisfaction over a period of 2 years after implantation of the ReZoom multifocal intraocular lens. METHODS Fifty-five eyes of 35 cataract patients were included in this retrospective study. Only patients with a preoperative photopic pupillary diameter superior to 3 mm were included. Monocular visual acuities and visual symptoms were compared at different time points. RESULTS Preoperative mean distance uncorrected visual acuity (UCVA) was 0.5+/-0.3 LogMAR, uncorrected intermediate visual acuity (UCiVA) at 50 cm was 0.6+/-0.3 LogMAR, and near uncorrected visual acuity (UNVA) was J7.8+/-0.6. Mean follow-up was 28.1+/-7.2 months. At 6 months, UCVA improved to 0.05+/-0.09 logMAR (p<0.001), UCiVA to 0.08+/-0.1 LogMAR (p<0.001), and UNVA to J2.4+/-0.4 (p<0.001). At 24 months, UCVA was 0.04+/-0.08 LogMAR, UCiVA was 0.07+/-0.1 LogMAR, and UNVA was J2.3+/-0.7. No significant differences were observed between the values at 6 months versus 24 months. At the 3-month visit, moderate glare and halo were reported by 10% and 13% of patients, respectively. The occurrence of visual symptoms decreased with time, with only 7% and 5% of patients reporting moderate glare and halo at the last visit, respectively. CONCLUSIONS The ReZoom lens provides quality vision at all distances. Between 6 and 24 months of follow-up, a further improvement of optical disturbances rather than uncorrected visual acuity may be expected.
