During cataract surgery, a patient's cloudy natural cataract lens is removed and replaced with a synthetic lens to restore the lens's transparency.Following surgical removal of the natural lens, an artificial intraocular lens implant is inserted (eye surgeons say that the lens is "implanted").In addition to these age related changes, infants may be born with congenital cataracts.Direct ocular trauma and some medications, specifically the long term use of steroids, may also result in cataract formation.Premium intraocular lenses are typically not covered by insurance companies as their additional benefits are considered a luxury and not a medical necessity.An accommodative intraocular lens implant has only one focal point, but it acts as if it is a multifocal IOL.

Metabolic changes of the crystalline lens fibers over time lead to the development of the cataract and loss of transparency, causing impairment or loss of vision.

These intraocular lenses are usually spherical, and they have their surface uniformly curved.

The multifocal intraocular lens is one of the newest types of such lenses.

Artificial intraocular lenses are used to replace the eye's natural lens that is removed during cataract surgery.

These lenses have been increasing in popularity since the 1960s, but it was not until 1981 that the first U. Food and Drug Administration (FDA) approval for this type of product was issued.
