Developments in cataract surgical devices and intraocular lenses (IOL) increased patient expectations and changed the practice patterns in ophthalmology. Nowadays, cataract surgery is considered as a refractive surgery. With multifocal IOLs, spectacle independence can be achieved with a good distance, intermediate and near visual acuity. This is associated with increased quality of life after cataract surgery.The most important disadvantages of multifocal IOLs are loss of contrast sensitivity and photic phenomena such as glare and halo. Although multifocal IOLs are more frequently associated with photic disturbances than monofocal IOLs, the trifocal IOLs have improved performance in photic phenomena when compared to bifocal IOLs. Recently, a new technology known as extended depth of focus (EDOF) IOLs have been developed. These lenses create a single elongated focal point to enhance the depth of focus, improving intermediate vision without compromising distance vision. Although EDOF IOLs provide better intermediate distance vision when compared to monofocal IOLs, near vision is not as good as trifocal IOLs. The most important advantage provided by the EDOF technology is lower rate of photic disturbances than trifocal IOL designs. The aim of this study was to compare the visual performance and patient-reported quality of life (QOL) outcomes following bilateral implantation of a novel non-diffractive wavefront shaping EDOF IOL (AcrySof® IQ Vivity, Alcon Research, TX, USA) and a trifocal IOL (AcrySof® IQ PanOptix, Alcon Laboratories, Fort Worth, TX).
The purpose of this study is to compare visual performance and quality of life (QOL) following bilateral implantation of a novel non-diffractive extended depth-of-focus (EDOF) intraocular lens (IOL) (AcrySof® IQ Vivity, Alcon, TX, USA) and a trifocal IOL (Acrysof® IQ PanOptix, Alcon, Fort Worth, TX) in a prospective comparative interventional case series.
