Multifocal IOL verses EDOF IOL

Multifocal verses Extend depth of focus (EDOF) implant. Over the last 5 years,newer IOL technology has revolutionized cataract surgery so that the rising patient expectations of excellent distance, intermediate and near vision can be met. The choice of implant (IOL) should depend on each patient’s needs after thorough questioning about their work and daily habits (e.g., use of computers, electronic devices etc.). The main IOL types that have been developed include bifocal, trifocal and EDOF IOLs. In general, trifocal IOLs enhance intermediate vision in comparison to bifocal IOLs, due to the addition of a third focal point, while maintaining good distance and near vision. The EDOF lenses provide better contrast sensitivity and decrease spectacle dependence for distance and intermediate vision, while also being associated with less visual disturbances than bifocal IOLs. However, EDOF lenses are inferior to the trifocal ones in terms of near vision, though this difference does not seem to alter patient satisfaction levels.
