In the young healthy eye, the natural lens flexes to focus on objects at varying distances. Multifocal IOLs are designed to provide similar benefits after cataract surgery, achieving good uncorrected vision from near to far. They accomplish this goal by acting more like bifocals or trifocals implanted into each eye. Multifocal IOLs are designed to provide a complete range of vision independent of the ciliary body muscle. To achieve this, they combine the functions of both apodized diffractive and refractive optics
Apodization is the gradual reduction or blending of diffractive step heights that distribute the appropriate amount of light to near and distant focal points. While apodized diffractive optics are designed to improve image quality and minimize visual disturbances, some visual effects may be expected early-on, including halos around lights in night-time conditions. These resolve with neuroadaptation in almost all cases after healing is complete.

Good news for people who have struggled with distorted vision due to astigmatism: toric IOLs are now available for implantation at the time of cataract surgery to cure not only cataract, but also the astigmatism some people have had for all their lives.
