Multifocal Intraocular Lenses and Extended Depth of Focus Intraocular Lenses

Abstract

Presbyopia and cataract patients' desire for increased spectacle independence after surgery is one of the main drivers for the development of multifocal intraocular lenses (MIOLs) and extended depth of focus (EDOF) intraocular lenses (IOLs). As education, biometry, diagnostics, surgical techniques, and MIOL/EDOF IOL designs have improved over the past decade, an increasing number of cataract surgeons have become cataract-refractive surgeons to help address this need. There is not 1 single MIOL/EDOF IOL, however, that suits all patients' needs. The wide variety of MIOLs and EDOF IOLs, their optics, and their respective impact on our patients' quality of vision have to be fully understood to choose the appropriate IOL for each individual; MIOL/EDOF IOL surgery has to be customized. This review article looks at the different optical aspects and clinical consequences of MIOLs/EDOF IOLs to help surgeons find an appropriate solution for each of their individual patients.
