AcrySof® ReSTOR® IOL

The ReSTOR® 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 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 accomodation. Unfortunately, this ability diminishes as we grow older, causing us to become dependent on bifocals or reading glasses. However, the ReSTOR® IOL was designed to provide quality near to distance vision by combining the strengths of apodized diffractive and refractive technologies.

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 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. The refractive region of the ReSTOR® IOL bends light as it passes through the lens to a focal point on the retina. This outer ring of the ReSTOR® IOL surrounds the apodized diffractive region and is dedicated to focusing light for distance vision.
