Extended depth-of-focus (EDOF) AcrySof® IQ Vivity® intraocular lens implant: a real-life experience

Extended depth-of-focus (EDOF) is a promising intraocular lens (IOL) technology for cataract surgery. The aim of the study was to report the real-life experience related to the implant of EDOF AcrySof® IQ Vivity® (Alcon Inc., USA) IOL.

The study was designed as a interventional, prospective, case series with 3 months of follow-up. Patients needing cataract surgery, without any other kind of ocular diseases, were recruited and implanted with AcrySof® IQ Vivity® IOL. We evaluated the refractive success of this IOL through complete ophthalmologic assessments and the administration of the Quality of Vision test. The main outcome measures were the refractive outcome; far, intermediate, and near vision; and Quality of Vision score.

We included 108 eyes (54 patients; age 62 ± 5 years). Intra-operative and post-operative complications were 0%. Thirty out of 100 eyes (28%) required toric IOL. Best-corrected visual acuity improved from 0.4 ± 0.3 LogMAR to 0.0 ± 0.0 LogMAR (p < 0.01). Refractive outcome was very good for far and intermediate visions, whereas a spherical addition of at least + 1.0D was required for near vision. The mean Quality of Vision score was of 15.5 ± 6.5. The most complained visual disturbances were haloes and glares, although resulting well-tolerated. Dynamic pupillometry findings well-correlated with the amount of complained post-operative visual discomforts.

AcrySof® IQ Vivity® IOL is a well-tolerated choice to correct far and intermediate vision. Spectacles are needed to optimize near vision. Our data strongly suggest dynamic pupillometry as a useful investigation to optimize post-operative refractive success.
