ReSTOR Multifocal Implant
Until recently, life without reading glasses or bifocals was not an option for most cataract patients.
With cataract surgery, patients now have a choice to implant the AcrySof® ReSTOR® lens. The ReSTOR 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.
Accommodation: The ability of the eye’s lens to change shape to focus on objects at various distances.
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 and distance vision by combining the strengths of apodized defractive 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.
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 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
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.
Refraction: Redirection of light rays as they pass through the lens.
The refractive portion 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.
The ReSTOR lens is a novel technology allowing for crisp distance and near vision. Studies report that 80% of people who have this lens implanted are free of all spectacle dependence. RsSTOR provides excellent reading vision, but it is often at a distance of 12- 14 inches. Of the 20% of patients who required glasses post ReSTOR, most were for intermediate distance, like working on the computer. ReSTOR is an exciting technology for those who wish to reduce their spectacle dependence. We have an extensive experience with implanting the ReSTOR lens, and would be glad to speak to you further.
