Cataract surgery involves replacing the natural opaque lens with a transparent intraocular lens (IOL). Monofocal IOLs allow you to see clearly from near or far, but not both.

Multifocal IOLs mostly have diffractive circles that optimize the transition from far vision to intermediate and near vision.

The insertion of the multifocal IOL is done in the same way as the insertion of a monofocal lens in a conventional cataract surgery.

Under normal lighting conditions, the central diffractive rings provide excellent distance, intermediate and near vision. In low light conditions, the outermost area of the lens further optimizes distance vision. The optical design of modern multifocal IOLs helps reduce the occurrence of halos.
