AcrySof ReSTOR Apodized Diffractive
Posterior Chamber Intraocular Lens (IOL) – SA60D3
Advances in Artificial Lens Technology
There have been great advances in artificial lens technology. Examples of this include the AcrySof® ReSTOR® lens and the AcrySof® IQ lens. Today, the AcrySof® family of lenses are among the most frequently implanted lenses in the world. This is largely due to the long-term clinical results of the lens. Furthermore, these lenses are made of a patented material developed specifically for the eye.

Finally, the opportunity for freedom from reading glasses and bifocals.
Until recently, life without reading glasses or bifocals was not an option for most Cataract:
A "clouding" of the lens in your eye. As light passes through the cataractous lens, it is diffused or scattered. The result is blurred or defocused vision. Accommodation: The ability of the eye's lens to change shape to focus on objects at various distances. . Unfortunately, this ability diminishes as we grow older1, causing us to become dependent on bifocals or reading glasses. However, the AcrySof® ReSTOR® IOL was designed to provide quality near to distance vision by combining the strengths of apodized IOL
Apodization: The gradual reduction or blending of the diffractive step heights. The application of apodization to intraocular lenses is a patented process by Alcon and can only be found in the AcrySof® ReSTOR® IOL.
Diffraction: The spreading of light. Occurs when light passes through discontinuities (i.e. steps or edges). In an optical system, light can be diffracted to form multiple focal points or images.
and refractive technologies. Similar technology has been used for years in microscopes and telescopes to improve image quality, and has now been patented for use in intraocular lenses by Alcon.
Apodization is the gradual tapering of the diffractive steps from the center to the outside edge of a lens to create a smooth transition of light between the distance, intermediate and near focal points. Diffraction involves the bending or spreading of light to multiple focal points as it passes through the lens. On the AcrySof® ReSTOR® IOL, the center of the lens surface consists of an apodized diffractive optic. This means that the series of tiny steps in that center area work together to focus light for near through distance vision
Distance vision: Refers to focal points that are typically 7 feet or further from your eyes. Items that typically fall within the distance range of vision are billboards, street signs, and movie screens.
Refraction: Redirection of light rays as they pass through the lens.
involves the redirection of light passing through the lens, to focus on the retina
Retina: The transmitter located at the back of your eye that sends the images to your brain.
The refractive region of the AcrySof® ReSTOR® IOL bends light as it passes through the lens to a focal point on the retina. This outer ring of the AcrySof® ReSTOR® IOL surrounds the apodized diffractive region and is dedicated to focusing light for distance vision.
When is it used?
The ACRYSOF ReSTOR IOL is used in adult patients with and without presbyopia, who desire near, intermediate and distance vision with increased independence from glasses following cataract surgery.
What will it accomplish?
The ACRYSOF ReSTOR IOL has been shown in a clinical study to provide good near, intermediate and distance vision with increased independence from glasses in patients who have undergone cataract surgery.

Sight changing, life changing.
Introducing a breakthrough in vision surgery. Now there's a revolutionary new way to potentially leave your glasses behind – introducing the AcrySof® ReSTOR® intraocular lens (IOL), a breakthrough in vision surgery. AcrySof® ReSTOR® has been uniquely designed to improve vision at all distances – up close, far away and everything in-between – giving cataract patients their best chance ever to live free of glasses.
Near vision: Refers to focal points that are typically 16 inches or closer to your eyes. This is also known as "reading vision." Items that typically fall within the near range of vision are books, newspapers, and medicine bottles.
patients. You now have an option. The AcrySof® ReSTOR®
Intraocular lens (IOL): An artificial lens that is implanted in the eye to replace the eye's clouded crystalline lens during cataract surgery.
is a unique technological innovation that can provide you with quality vision throughout the entire visual spectrum – near through distance – with increased independence from reading glasses or bifocals!
What is it?
The ACRYSOF ReSTOR Apodized Diffractive Optic Posterior IOL is an artificial lens implanted in the eye to restore vision after a clouded natural lens (cataract) is removed.
The lens of the IOL is convex on both sides (biconvex) and made of a soft plastic that can be folded prior to insertion, allowing placement through an incision smaller than the optic diameter of the lens.
After surgical insertion into the eye, the lens gently unfolds to restore vision. The supporting arms (haptics) provide for proper positioning of the IOL within the eye.
How does it work?
The ACRYSOF ReSTOR IOL is intended to be positioned in the posterior chamber of the eye, replacing the natural lens.
This position allows the IOL to correct the visual impairment of aphakia (absence of the natural lens).
The ACRYSOF ReSTOR IOL has a biconvex optic that is shaped using a special process called apodized diffraction to provide increased depth of focus.
How does the AcrySof® ReSTOR® IOL work?
As we perform daily activities such as reading, watching television or working at the computer, our eyes are constantly focusing on objects at varying distances – up close, far away and everything in-between. The ability to quickly change focus throughout this range of vision is called
