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.The development of intraocular lenses brought about an innovation as patients previously did not have their natural lens replaced and as a result had to wear very thick eyeglasses or some special type of contact lenses.Presently, IOLs are especially designed for patients with different vision problems.Phacoemulsification is the most commonly performed cataract procedure in the developed world.

Either topical, peribulbar, or retrobulbar local anesthesia is used, usually causing little or no discomfort to the patient.

They are often referred to as "premium" lenses because they are multifocal and accommodative and allow the patient to visualize objects at more than one distance, removing the need to wear eyeglasses or contact lenses.

Premium intraocular lenses are those used in correcting presbyopia or astigmatism.

In order to achieve the most benefit from a toric lens, the surgeon must rotate the lens to be on axis with the patient’s astigmatism.

Intraoperative wavefront analysis, such as that provided by the ORA System developed by Wavetec Visions Systems, can be used to assist the doctor in toric lens placement and minimize astigmatic errors.
