Reading Performance Following Contralateral Implantation of an Extended Depth of Focus (EDOF) IOL and a Hybrid EDOF Multifocal IOL

Purpose To assess objective reading performance at intermediate and near distances using the Salzberg Reading Desk (SRD) (SRD Vision) in patients with cataract who underwent the implantation of a diffractive extended depth of focus intraocular lens (EDOF IOL) in the dominant eye and a hybrid multifocal EDOF IOL in the non-dominant eye. Methods This prospective, non-comparative, interventional study included 46 eyes of 23 patients with cataract who underwent bilateral cataract surgery with implantation of the DFR00V Tecnis Synergy IOL (Johnson & Johnson Surgical Vision) in the non-dominant eye and the DXR00V Tecnis Symfony OptiBlue IOL (Johnson & Johnson Surgical Vision) in the dominant eye. At postoperative 6 months, the Salzburg Reading Desk was used to assess distance-corrected reading performance at near and intermediate distances. Results Although the monocular reading acuity at the preferred intermediate distance was statistically significantly better in the eyes implanted with the DXR00V IOL, it was better with the DFR00V IOL at preferred near distances. The mean binocular distance-corrected preferred intermediate and near reading acuity was 0.07 ± 0.09 (20/23) and 0.13 ± 0.09 (20/27) logarithm of the minimum angle of resolution, respectively. Other parameters of reading performance, such as reading speed, reading distance, reading time, and smallest scale log print size, were similar between the two IOL groups when assessed monocularly. Conclusions Implanting a DFR00V IOL in the non-dominant eye and a diffractive DXR00V IOL in the dominant eye resulted in excellent binocular reading acuity and speed at intermediate and near distances.
