To assess the visual outcomes obtained with a new version of diffractive extended depth of focus intraocular lens (EDFIOL), the Tecnis Symfony.

: This study enrolled 70 eyes of 35 patients who had bilateral implantation of the extended depth of focus intraocular lens (IOL), after lensectomy. Monocular and binocular uncorrected (UDVA) and corrected distance visual acuity (DCVA), monocular and binocular uncorrected (UNVA) and distance-corrected near visual acuity (DCNVA) at 40 cm, binocular uncorrected and distance-corrected intermediate visual acuity (DCIVA) at 60cm, were evaluated over 6 months.

The mean refractive and visual acuity results were stable during the follow-up period (P>0.05). Six months postoperatively, monocular UDVA and UNVA significantly improved in comparison to preoperative monocular DCVA and DCNVA, respectively. The binocular uncorrected distance (UDVA), intermediate (UIVA), and near (UNVA) visual acuities were 20/30 or better in 100%, 94.2% and 94.2% of patients respectively, 6 months postoperatively. The corrected distance (DCVA), intermediate (DCIVA), and near (DCNVA) visual acuities were 20/30 or better in 100%, 82.9%, and 82.9% of patients respectively. The mean postoperative sphere was -0.78 0.41 More than 89.4% of patients reported no or mild halos, glare, starbursts, or other photic phenomena.

Bilateral implantation of the extended depth of focus IOL provided good refractive and visual outcomes at far, intermediate, and near distances, being stable during the follow-up period.
