Presbyopic intraocular lenses (IOLs) based on simultaneous vision represent a compromise between perceptual benefit and cost at near far distances. We evaluated this for simulated bifocal IOLs with varying energy distributions additions using SimVis Gekko under different adaptation conditions. Presenting multifocal corrections after blur an abrupt transition of least 5s improves acceptance. Smooth transitions to multifocality also improve acceptance, independently previous adaptation. Corrections low show more visual degradation without equivalent near. These results can be useful IOL designers clinicians maximize adoption IOLs.
