An intraocular lens is a synthetic implant that serves to replace the natural lens of a person's eye. Intraocular lenses help restore the focusing power of a patient’s eye once the clouded lens is removed during a cataract surgery.
Multifocal and accommodating IOLs, such as Trulign and Crystalens, allow patients to see clearly at any distance, unlike the older monofocal IOLs that require patients to wear glasses that use thick corrective lenses. Monovision IOLs are used in cases where lenses in both eyes are removed. IOL implantation has been approved by the FDA since 1981 for patients who are 18 and older. The procedure is not recommended for children due to the risk of inflammation and an increased chance of developing glaucoma in the future.
