ReSTOR Multifocal IOL

About the AcrySof® IQ ReSTOR® IOL

Apodized Diffractive Optics for a Full Range of Vision

In the healthy eye, the lens flexes to focus on objects at varying distances. The AcrySof® IQ ReSTOR® IOL was designed to provide a complete range of vision independent of the ciliary body muscle. To achieve this, the AcrySof® IQ ReSTOR® IOL combines the functions of both apodized diffractive and refractive regions.

Apodization is the gradual reduction or blending of diffractive step heights. The AcrySof® IQ ReSTOR® IOL features patented apodized diffractive technology that distributes the appropriate amount of light to near and distant focal points, regardless of the lighting situation. The apodized diffractive optics are also designed to improve image quality and minimize visual disturbances—a significant improvement over traditional multifocal technologies.1

Apodized Diffractive

The apodized diffractive optics are found within the central 3.6 mm optic zone of the lens. This area comprises 9 concentric steps of gradually decreasing (1.3–0.2 microns) step heights that allocate energy based on lighting conditions and activity, creating a full range of quality vision—near to distant.



The refractive region of the optic surrounds the apodized diffractive region. This area directs light to a distance focal point for larger pupil diameter, and is dedicated to distance vision.

+3.0 D Add Power for True Performance at All Distances2

The AcrySof® IQ ReSTOR® IOL +3.0 D (SN6AD1) incorporates a +3.0 diopter correction at the lenticular plane (approximately +2.5 D at the spectacle plane), for improved intermediate vision over the original AcrySof® IQ ReSTOR® IOL +4.0 D (SN6AD3), with similar near and distance visual acuity.
