Current visual outcomes expectations of cataract patients are similar to those of refractive surgery patients. Their desire is to be spectacle independent for far, intermediate and near vision activities. Different options are available including: mono-vision and presbyopia correcting intraocular lenses (IOL). Presbyopia correcting IOLs include accommodative, multifocal, trifocal and extended depth of focus (EDOF) IOLs. The Vivity Extended Vision IOL is not a multifocal IOL but due to its design, it provides better intermediate and near VA compared to a monofocal IOL.
The study is concerned with the visual performance of the Vivity Extended Vision IOL at distance, intermediate and near when one of the eyes is targeted for emmetropia and the other is targeted for slight myopia. Patients will serve as their own controls with visual performance evaluated against corrected vision with a target of emmetropia in both eyes.
