Comparison of Quality of Vision After Bifocal and Extended Depth of Focus Intraocular Lens Implantation

This study was conducted from 2018 to 2020. This study included patients who were with presence of cataract in both eyes, age between 50 and 80 years, and corrected distance visual acuity (CDVA) of both eyes under 20/40. Phacoemulsification cataract surgery was arranged for both eyes for all patients. The study groups of IOL models include EDOF Symfony IOL (AMO, Santa Ana, CA, USA), bifocal Restor +2.5D IOL (Alcon, Fort Worth, TX, USA), and monofocal Sensar AR40e IOL (AMO, Santa Ana, CA, USA). The patients were routinely examined preoperatively as well as 1 month after surgery for far and near visual acuity (in LogMAR unit). Contrast sensitivity, wavefront aberration and quality of vision questionnaire was measured at the 1-month postoperative visit. These aforementioned outcomes were recorded and compared between groups.
