AcrySof® ReSTOR® IOL
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 patients. You now have an option. The AcrySof® ReSTOR® IOL Intraocular lens 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.
Unfortunately, this ability diminishes as we grow older, 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 diffractive 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 through distance vision.
Refractive
Refraction involves the redirection of light passing through the lens, to focus on the retina. 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.
Glossary
Accommodation: The ability of the eye's lens to change shape to focus on objects at various distances.
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.
(IOL): An artificial lens that is implanted in the eye to replace the eye's clouded crystalline lens during cataract surgery.
Retina: The transmitter located at the back of your eye that sends the images to your brain.
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. 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.
