AcrySof® ReSTOR® IOL
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.
A new look on life with the AcrySof®
ReSTOR® IOL
The AcrySof® ReSTOR® IOL gives you the best possibility to have distance vision, in addition to the ability to read and perform close-up tasks, without the need for glasses. However, results of the clinical trials indicated that there is a slightly greater chance of having difficulty with halos or rings around lights (five out of 100) and glare (five out of 100), as compared to a monfocal IOL (one or two out of 100). Over time, some people grow accustomed to these disturbances and cease to notice them, while others may continue to see them long after surgery.
 Previously, IOLs used in cataract procedures provided good functional distance vision, but offered little benefit for a full range of vision. That meant that people with those IOLs would still need reading glasses from time to time. Now there is a new option – the AcrySof® ReSTOR® IOL is designed to improve vision at all distances.
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.
