Presbyopia and Presbyopia Correcting Implants

Dr. Khater is proud to offer two different styles of presbyopia correcting implants: ReZoom and ReSTOR.

Presbyopia

bulletPresbyopia is a term used to describe the loss of near or reading vision due to changing.
bulletPresbyopia affects nearly every adult over the age of 50.1
bulletPresbyopia is caused in part by a gradual hardening of the natural crystalline lens of the eye. As the lens gets harder and less flexible, the eye’s ability to switch from seeing objects at a distance (driving) to seeing objects that are near (reading) is compromised. (See image at right.)

bulletThe most commonly prescribed treatments for the loss of near or reading vision from presbyopia are reading glasses or bifocals.
bulletToday, depending upon the lifestyle and eye health needs of an individual, a person with cataracts and presbyopia can be treated with a new generation of presbyopia-correcting intraocular lens implants.
bulletOn May 3, 2005, CMS (Centers For Medicare and Medicaid Services) published a ruling that made presbyopia-correcting intraocular lens technology accessible to a broad range of people.

Intraocular Lenses: An Overview

bulletIntraocular lenses (IOLs) are small devices – with an optic usually about 6.0 mm in diameter – that are used to replace the natural crystalline lens of the eye when the lens of the eye becomes clouded due to a cataract and light can no longer pass clearly through the eye to focus on the retina.
bulletApproximately 14 million IOLs are implanted worldwide each year.
bulletPrior to FDA approval of multifocal IOLs that correct for distance, intermediate and/or near vision, IOLs provided correction of vision at one plane – usually distance vision. Patients were required to wear glasses, bifocals or trifocals for intermediate and near vision.
bulletIntraocular lenses are implanted by ophthalmologists, highly trained medical doctors who have completed a four- to five-year residency program following medical school.

The ReZoom™ Multifocal IOL (Lens)

bulletThe ReZoom™ Multifocal Lens is implanted in the eye and replaces the cataractous natural crystalline lens of the eye. The lens is normally implanted in both eyes.
bulletThe ReZoom™ Multifocal Lens is designed to provide:
- Sharp distance vision (driving, golfing, walking)
- Critical intermediate vision (computer use, cooking, talking face-to-face)
- Crisp near vision (reading)
bullet92% of people receiving the ReZoom™ Multifocal Lens technology function independent of glasses in most daily situations (see chart at right).

bulletThe ReZoom™ Multifocal Lens, featuring Balanced View Optics™ technology (see illustration below), is designed to deliver a full range of vision – near, intermediate and distance.
bulletThe ReZoom™ Multifocal Lens is indicated for the correction of cataracts in adult patients with or without presybopia.

For More Information, please see the ReZoom IOL Patient Information Brochure.

The ReSTOR ® Apodized Diffractive IOL

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.

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.

The AcrySof ReSTOR ® Intraocular Lens has been shown in a clinical study to provide good near, intermediate and distance vision with increased independence from glasses.
