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

Clear corneal phacoemulsification and IOL implantation were performed by 2 surgeons (Chao-Kai Chang and Hung-Yuan Lin) by using an identical technique to minimize differences in surgically induced aberrations between groups. The surgical process involved topical anesthesia, a 3-step clear corneal incision (2.75 mm) at 180° (temporal in both eyes), a 5.0-mm continuous curvilinear capsulorhexis, phacoemulsification using the stop-and-chop technique, IOL implantation with an injector, IOL centration, and a sutureless incision. The study 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).
