Sumario: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 surgery with a toric or non-toric EDOF IOL (Tecnis Symfony), and 96 patients completed the final assessment at 4 to 6 months. Binocular corrected 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 were evaluated. 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% of patients, respectively. Binocular UNVA was 0.63 (decimal) or better in 76% of patients. Overall, 76% of the patients achieved spectacle independence across all distances, and more than 85% reported no or mild dysphotoptic phenomena. On a scale of 0 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 visual acuity. The visual results were associated with prominent levels of spectacle independence and patient satisfaction.
