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

Purpose 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 (R) IQ Vivity (R) (Alcon Inc., USA) IOL. Methods 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 (R) IQ Vivity (R) 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. Results 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. Conclusions AcrySof (R) IQ Vivity (R) 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.
