Accommodating & Multifocal Intraocular Lenses (IOLs) offer lens choices for patients requiring Cataract Surgery. Cataract Surgery is a procedure used to treat compromised visual acuities resulting from the clouding of the eye's natural crystalline lens.
During cataract surgery, the natural clouded lens is removed and then is replaced by an intraocular lens (IOL). The type traditionally used is a standard monofocal IOL (or a toric model for the correction of astigmatism), designed to target vision at a single focal point. Most patients opt for good distance vision but typically need glasses for near and intermediate tasks such as reading and computer use.
Accommodating and Multifocal IOLs are lens replacement options that are designed to treat a cataract, plus deliver a more natural range of vision, with less dependence on intermediate and near vision glasses.
Accommodating IOLs are not fixed like a standard monofocal lens but instead are designed to flex or "accommodate" like the natural eye's lens. This "accommodation" provides a continuous range of vision with optimal intermediate, near, and distance vision. Accomodating IOLs are also available in a toric model for the correction of astigmatism.
Multifocal IOLs are not uniform like a standard monofocal lens, but instead are designed to contain different visual zones to sharpen near and distance vision. Multifocal IOL's may provide better near vision for tasks like reading, but may be associated with more blurring and glare than an accommodating IOL or a standard Monofocal IOL.
Accommodating and Multifocal IOLs are appropriate for cataract patients who, because of their lifestyle, job, or hobbies would like a more natural range of vision. If you require treatment for cataracts, you and your Surgical Specialist may want to discuss the risks and benefits of these lens options to see if they are right for you.
