Optical Quality Differences Between Three Multifocal Intraocular Lenses: Bifocal Low Add, Bifocal Moderate Add, and Trifocal

Abstract

The trifocal IOL provides a better optical quality at the -1.5 D focal point. However, the optical quality of the trifocal IOL significantly decreases compared to the bifocal IOLs at far distance and -2.5 D focal points.
