If the patient is operated on with a multifocal intraocular lens, in principle they will not need to wear glasses, since these lenses correct all refractive errors. Multifocal intraocular lenses provide the closest feeling of perfect vision regardless of focal length.
However, they are not suitable for all patients. Certain limiting factors include the severity of the patient's initial vision problem, individual lifestyle, and vision correction needs.
A multifocal intraocular lens allows patients to see clearly at all distances. These intraocular lenses assign different optical powers. The different optical powers are created by the design that incorporates concentric rings on the surface of the lens. These allow images at a variety of distances to be in sharp focus.
It can take some time for people to adjust to multifocal intraocular lenses because the focusing power that the lenses provide is different than what people are used to. Since they are based on a different design than the bifocal or multifocal optical lenses used in glasses, the brain may need time to adjust.
To make fitting easier, cataract surgeons recommend implanting multifocal intraocular lenses in both eyes, rather than just one.
