Purpose: Evaluation of the visual and refractive results 3 months after implantation of a diffractive extended range of vision (ERV) intraocular lens (IOL) during cataract surgery.

Methods: In a prospective multicentre study, patients with a calculated postoperative corneal astigmatism of ≤ 1.5 D received a diffractive ERV IOL (TECNIS Symfony, model ZXR00, Abbott Medical Optics, USA) during cataract surgery. After 3 months, the monocular and binocular corrected and uncorrected far, intermediate and near visual acuity, as well as refraction, were evaluated.

Results: 18 patients (36 eyes) with a mean age of 63.34 ± 4.6 years underwent bilateral cataract surgery. After 3 months, the binocular uncorrected distance visual acuity (UDVA) of logMAR was - 0.05 ± 0.11 and the corrected distance visual acuity (CDVA) of logMAR - 0.14 ± 0.05. Binocular uncorrected intermediate (UIVA) and near visual acuity (UNVA) were logMAR - 0.09 ± 0.02 and 0.19 ± 0.09, respectively. A target refraction of ± 0.75 D was reached by 89 % of the patients.

Conclusion: Implantation of an extended range of vision intraocular lens offers an effective way for visual rehabilitation at far and intermediate distances. Near vision is still in a functional range.
