Abstract

Purpose: To evaluate the visual performance after bilateral implantation of an extended depth of focus (EDOF) intraocular lens (IOL).

Methods: In this multicenter, prospective, observational study, the postoperative outcomes of 96 patients who underwent bilateral cataract surgery with EDOF IOL (TECNIS Symfony) were assessed.

Results: Mean decimal visual acuity results showed a binocular corrected distance visual acuity (CDVA) of 1.10 ± 0.18, uncorrected distance visual acuity (UDVA) of 1.04 ± 0.17, uncorrected intermediate visual acuity (UIVA) of 0.96 ± 0.16, and uncorrected near visual acuity (UNVA) of 0.68 ± 0.18. Overall, 76% of the patients achieved spectacle independence across all distances, and more than 85% reported no or mild dysphotoptic phenomena. On a scale from 0 to 10, 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 and intermediate visual outcome and functional near visual acuity. The visual results were associated with high levels of spectacle independence and patient satisfaction.
