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

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.

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!

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 accommodation

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.

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.

Apodized Diffractive

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
