The innovations in phacoemulsification surgery and advances in surgical equipment ensure a safe extraction of the crystalline lens and implantation of intraocular lenses (IOL). As a result of developing intraocular lens technologies and changing patient demands, many multifocal, accommodative, toric, toric-multifocal, and extended depth of focus (EDOF) IOLs have been introduced and the original aim of restoration of far vision with implanted monocular IOLs has been evolved to an objective of improved vision at different distances with total spectacle independence. This study aimed to compare the visual acuity at different distances, contrast sensitivity, spectacle needs, photic phenomena, and quality of life parameters of patients bilaterally implanted with a low add bifocal (Tecnis ZKB00) or an EDOF IOL (Tecnis Symfony), both with planned mini-monovision to improve near vision. In this regard, binocular logMAR uncorrected visual acuities (UVA), monocular defocus curves, CS with CSV 1000-E and Pelli-Robson Test (PRT), spectacle needs and quality of life parameters with NEI RQL-42 questionnaire were evaluated at postoperative 1, 3, and 6 months.
