Purpose: To evaluate visual performance after bilateral implantation of an extended depth of focus (EDOF) intraocular lens(IOL). Methods: This multicenter, prospective, observational study included 100 patients who underwent bilateral cataract surgerywith a toric or non-toric EDOF IOL (Tecnis Symfony), and 96 patients completed the final assessment at 4 to 6 months. Binocularcorrected distance visual acuity and uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity(UIVA), and uncorrected near visual acuity (UNVA), spectacle independence, visual symptoms, and patient satisfaction wereevaluated. Results: Mean decimal visual acuity results showed a binocular corrected distance visual acuity of 1.10 ± 0.18, UDVA of 1.04 ±0.17, UIVA of 0.96 ± 0.16, and UNVA of 0.68 ± 0.18. Binocular UDVA and UIVA were 0.8 (decimal) or better in 98% and 94% ofpatients, respectively. Binocular UNVA was 0.63 (decimal) or better in 76% of patients. Overall, 76% of the patients achievedspectacle independence across all distances, and more than 85% reported no or mild dysphotoptic phenomena. On a scale of0 to 10, the median patient satisfaction score was 9 for far, 9.5 for intermediate, and 8 for near vision. Conclusions: The Symfony EDOF IOL provided excellent distance, intermediate visual outcome, and functional near visualacuity. The visual results were associated with prominent levels of spectacle independence and patient satisfaction.
