The 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 (IOL) 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 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 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.

Finally, quality vision and true freedom from glasses for 80 percent of patients

AcrySof® ReSTOR®/Monofocal Overall Spectacle Wear

During the AcrySof® ReSTOR® IOL clinical studies, patients experienced lifestyle enhancement through quality vision, and greater freedom from reading glasses and bifocals. In fact, according to the AcrySof® ReSTOR® clinical studies, four out of five patients with the AcrySof® ReSTOR® IOL reported never wearing glasses following cataract surgery in both eyes, compared to only 1 out of 10 patients with monofocal lenses. This is the highest level of freedom from glasses ever demonstrated in an IOL clinical trial.

Additionally, the AcrySof® ReSTOR® clinical studies indicated that nearly 94 percent of the study subjects were so satisfied with their new quality vision that they would have the AcrySof® ReSTOR® IOL implanted again.
