An intraocular lens (IOL) is an artificial replacement lens implanted when a patient's natural lens has been surgically removed during cataract surgery. A wide variety of replacement lenses is available to cataract patients. Each type of lens has its own advantage for post-surgery vision, The most effective lens to use depends on the patient's preferences and particular vision goals, which can differ according to individual occupations and lifestyles. IOLs often eliminate the need for glasses or contacts after cataract surgery, conveniently providing most patients with clear vision.
Multifocal Intraocular Lenses
Multifocal intraocular lenses are designed to correct vision at varying distances. They are appealing to those who would prefer not to wear eyeglasses or contact lenses after surgery, or to require corrective lenses only for certain activities.

Toric Intraocular Lenses for Astigmatism
Until recently, a patient with astigmatism did not have the same opportunities as other cataract patients to have vision corrected with IOLs. Typically, an astigmatic patient would require an additional surgical procedure, such as LASIK, to correct vision after cataract surgery. If the patient did not want to undergo another surgical procedure, the only option for correction would be wearing contact lenses or glasses.
Toric IOLs, however, are specially designed to correct for astigmatism when implanted during cataract surgery. They provide complete vision correction from a single surgical procedure.
