Abstract:AIM: To evaluate clinical outcomes after implantation of a new diffractive aspheric multifocal intraocular lens (IOL) with +3.00 addition power. METHODS: This is a retrospective, consecutive case series of cataract patients who underwent bilateral implantation of the Optiflex MO/HF D012 (Moss Vision Inc. Ltd, London, UK) multifocal IOL. Patients followed for 6mo were included in the study. Data on distance, intermediate and near visual acuity, refractive error [manifest spherical equivalent (MSE)], contrast sensitivity, adverse events, subjective symptoms, spectacle independence and patient satisfaction [visual function questionnaire (VFQ)-25 questionnaire] were retrieved from electronic medical records and analyzed. RESULTS: Forty eyes of 20 patients with a mean age of 66.7±8.5y (range: 53-82) were included in the study. Mean uncorrected distance, near and intermediate visual acuity remained stable through postoperative visits and was 0.19±0.19 logMAR, Jaeger 4 and Jaeger 3 respectively at the 6mo visit. At the end of postoperative 6mo, MSE was -0.14±0.42 diopters (D) and 98% of the eyes were within 1.00 D of target refraction. Postoperative low contrast (10%) visual acuity remained stable (P=0.54) through follow up visits with a mean of 0.35±0.17 logMAR at the 6mo visit. There were no reported adverse events. None of the patients reported subjective symptoms of halo or glare. Spectacle independence rate was 90%. Mean VFQ-25 questionnaire score was 93.5±6.12. CONCLUSION: The Optiflex MO/HF-DO12 IOL was safely implanted and successfully restored distance, intermediate and near visual acuity without impairing contrast sensitivity. High levels of spectacle independence were achieved at all distances including intermediate distance.
