What are my lens choices?
The artificial replacement lens used to replace your cataracts is called an intraocular lens or IOL for short. These IOLs are very small and are highly advanced medical devices that are designed to mimic your natural crystalline lens.
Different types of implantable lenses are designed to meet individual eye health and lifestyle needs, so be sure to talk to your doctor about which lens is right for you.
Monofocal lens: This traditional lens will give you good vision for seeing objects in the distance, such as when you’re driving. For near or intermediate vision, such as reading or surfing the Internet, you will typically need to wear glasses. There are many types of monofocal lenses that you can choose. You can ask your doctor which one is best for you.
Toric lens: While a standard IOL can improve your vision by replacing your eye’s cloudy natural lens, if you have astigmatism you may still need glasses or contacts to see clearly. However, depending upon your priorities and lifestyle, your doctor may recommend a premium toric IOL, such as the TECNIS® Toric IOL. Its advanced design replaces your cloudy natural lens, corrects your astigmatism, and typically provides crisp, clear vision with less reliance on glasses for distance vision. However, after surgery, you may still need glasses to ensure optimal near vision.
Multifocal lens: These types of lenses are designed to be able to provide patients the ability to see objects clearly at different distances without glasses—near, far, and everywhere in between. The lens material distributes light to different distances, which the eye can focus on for sharper vision. For people who are active and find wearing glasses inconvenient, the multifocal lens can be the optimal choice.
Lenses with the most advanced technological innovations are designed to give nearly everyone independence from glasses. For example, the TECNIS® Multifocal lens is intended to give people high-quality vision in a range of light conditions, including low light situations, such as driving at night and reading a menu in a dimly lit restaurant.
Some patients may notice rings or halos around light when driving at night right after surgery. But over time, the visual impression of these rings typically lessens or goes away, as your eye and brain adapt to the lens. You can find more information about this lens at www.TECNISMultifocal.com.

Accommodating lens: This type of lens is designed to shift or move with the muscles in the eye to help patients focus at different distances. These lenses attempt to change focal points by moving back and forth in the eye—closer to the front of the eye for near vision and then toward the back of the eye for distance vision. With an accommodating lens, some people don’t require glasses for up-close vision.

Important Safety Information for TECNIS® Toric IOL
The TECNIS® Toric Intraocular Lens (IOL) is an artificial lens designed to be placed inside a patient’s eye to replace their natural lens after cataract surgery. The lens is used to correct corneal astigmatism (a focusing error in the eye where near and far objects appear blurry) and to improve distance vision in adult patients. Talk to your eye doctor to find out if the TECNIS® Toric IOL is right for you.
Existing eye conditions and surgical difficulties may increase the risk of complications. Your doctor will determine if you are a good candidate for lens replacement. There is a possibility that the lens could be placed incorrectly or could move inside the eye and you may experience vision problems or distortions. This may require a second surgery to have your doctor correctly reposition the lens. Although you may be able to see better without glasses or contact lenses at far distances, you may still need reading glasses.
If your eye is not healthy, you may not get the full benefits of the TECNIS® Toric IOL. Before surgery your doctor will check to see if you have any eye diseases. If you wear contact lenses, your doctor may ask that you stop wearing them before being tested for the lens. Your doctor will tell you what activities to avoid while you are recovering from surgery.
In 3.4% of patients, side effects with TECNIS® Toric included the need for a second surgery to reposition the lens or repair the retina. Other side effects included swelling/thickening of the retina (2.9%), and separation of the retina from the surrounding tissues (less than 1%).
Federal law restricts these devices to sale by or on the order of a physician.
Important Safety Information for TECNIS® Multifocal IOL
Approved Use: The TECNIS® Multifocal Intraocular Lens (IOL) is an artificial lens designed to be placed inside a patient’s eye to replace their natural lens after cataract surgery. The lens is used to improve vision at all distances in adult patients. Talk to your eye doctor to find out if the TECNIS® Multifocal IOL is right for you.
Warnings: Existing eye conditions and surgical difficulties may increase the risk of complications. Your doctor will determine if you are a good candidate for lens replacement. Under poor visibility conditions, such as dim light or fog, your vision may be reduced. You may perceive halos and/or glare around lights under nighttime driving conditions and therefore may need to take extra care when driving at night. A very small number of patients (less than 1%) may not be satisfied and request removal of their multifocal IOL.
Precautions: If your eye is not healthy (including glaucoma) you may not get the full benefits of the TECNIS® Multifocal IOL. Before surgery your doctor will check to see if you have any eye diseases. If you wear contact lenses, your doctor may ask you to stop wearing them before being tested for the lens. Your doctor will tell you what activities to avoid while you are recovering from surgery. There is a chance that your vision with a multifocal IOL may not be good enough to perform very near or detailed “up-close” work without glasses.
Side Effects: In less than 4% of patients, side effects with the TECNIS® Multifocal IOL included macular edema, a swelling/thickening of an area of the retina. In less than 1% of patients, there was a need for a second surgery to replace, reposition, or remove the new lens or to repair structures of the eye.
