Multifocal IOLs
Multifocal IOLs allow for full vision correction at near, intermediate and far distances, completely eliminating the need for eyeglasses or contact lenses for most patients. Some IOLs can also correct astigmatism. The procedure to implant a multifocal IOL is performed at the conclusion of cataract surgery.
These choices were not always available for cataract patients. In the past, cataract surgery only involved monofocal lenses, which could only focus on objects near or far, but could not adjust to accommodate varying distances. These patients still had to rely on glasses or contact lenses after surgery in order to see clearly at all distances, especially for those older patients suffering from presbyopia.
Accommodative IOLs
Crystalens is the only FDA-approved presbyopia correcting intraocular lens (IOL) that corrects vision through accommodation. The Crystalens IOL is made with flexible silicone that has hinges on each side allowing it to move with the eye muscle, flexing and accommodating seamlessly so you can focus on the objects around you at any distance. In other words, it dynamically adjusts to your visual needs.
Accommodation is the ability to shift focus between nearby and distant objects, providing sharper vision at multiple distances in order to minimize the use of glasses. Other IOLs are unable to accommodate and those patients may require additional vision correction with glasses or contact lenses.
