ReSTOR® Intraocular Lens Implants
A New Age In Cataract Care
Until recently, life without reading glasses or bifocals was not an option for most cataract patients. You now have an option. The AcrySof® ReSTOR® 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. Unfortunately, the ability to change focus throughout this range of vision diminishes as we grow older, causing us to become dependent on bifocals or reading glasses.
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.
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 and distance vision.
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 surrounds the apodized diffractive region and is dedicated to focusing light for distance vision.
