Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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. Some may have already enjoyed freedom from glasses and would like to continue after the cataracts are removed. Different options are available. These options include: mono-vision and presbyopia correcting intraocular lenses (IOL). Presbyopia correcting IOLs include accommodative, multifocals and extended depth of focus (EDOF) IOLs. In a previous study that evaluated the visual outcomes of an EDOF IOL when combined with a multifocal IOL with a +3.25 D add in patients with or without astigmatism undergoing routine cataract surgery showed good outcomes with high patient satisfaction and less dependance on glasses for intermediate and near activities. As technology evolves, new lens models are available in the market. The purpose of this study is to evaluate the latest EDOF and a hybrid multifocal lenses when combined.
