Explore the tabs below to learn:

  • How this innovative technology works
  • Key design differences between the AcrySof® IQ ReSTOR® +2.5 D IOL and the AcrySof® IQ ReSTOR® +3.0 D IOL
  • How best to select an AcrySof® IQ ReSTOR® IOL for your patients based on their lifestyle needs and vision goals

AcrySof® IQ ReSTOR® IOLs can help reduce spectacle dependence for all kinds of activities.

Apodized Diffractive Technology Overview & Design Comparisons

Both the AcrySof® IQ ReSTOR® +2.5 D IOL and the AcrySof® IQ ReSTOR® +3.0 D IOL feature an apodized diffractive optical structure. To understand the differences between the lenses, it is important to first understand the principles behind this unique technology.

Diffractive optics

A diffractive optical structure allocates light to multiple focal points by creating zones, or steps, on the anterior surface of the lens.

  • Step height controls the distribution of light between the near and distance focal points.
  • The higher the step height, the more light is distributed to the near focal point.
  • Distance between steps determines the add power of the lens.
AcrySof® IQ ReSTOR® IOLs feature a diffractive anterior surface.


Apodization

Apodization is the gradual shortening of step heights toward the periphery of the diffractive zone.

  • Lower step heights distribute more light energy to the distance focal point.
  • As pupil size increases, more light is allocated to distance.
  • Apodization is intended to improve distance vision in mesopic conditions, such as night driving.
AcrySof® IQ ReSTOR® IOLs feature apodization.

 

Designed to deliver sharp distance vision in all lighting conditions with the goal of reducing spectacle dependence over a range of distances2

AcrySof® IQ ReSTOR® +2.5 D IOL features ACTIVEFOCUSTM optical design2,4:
  • Fewer diffractive steps (7) spaced further apart
  • An 18% smaller diffractive region (3.4 mm diameter, 8.4 mm2 area)
  • A 6% larger peripheral zone that allocates more light to distance as pupil size increases
  • A 0.94 mm-diameter central refractive zone dedicated 100% to distance
  • Greater negative asphericity (-0.2 μm)
AcrySof® IQ ReSTOR® +3.0 D IOL features a pupil-adaptive optical design engineered to optimize performance in all lighting conditions3,4:
  • More diffractive steps (9) spaced closer together
  • A larger diffractive region (3.6 mm diameter, 10.2 mm2 area)
  • A 0.86 mm-diameter central diffractive zone dedicated 60% to the near focal point (40% to distance)
  • Negative asphericity (-0.1 μm)


*Broadest range of vision across all Alcon® IOLs approved in the United States.

ACRYSOF® IQ RESTOR® FAMILY OF INTRAOCULAR LENSES IMPORTANT PRODUCT INFORMATION

CAUTION: Federal (USA) law restricts this device to the sale by or on the order of a physician.

INDICATIONS: The AcrySof® IQ ReSTOR® Posterior Chamber Intraocular Lens (IOL) is intended for primary implantation for the visual correction of aphakia secondary to removal of a cataractous lens in adult patients with and without presbyopia, who desire near, intermediate and distance vision with increased spectacle independence. The lens is intended to be placed in the capsular bag.

WARNINGS / PRECAUTIONS: Careful preoperative evaluation and sound clinical judgment should be used by the surgeon to decide the risk/benefit ratio before implanting a lens in a patient with any of the conditions described in the Directions for Use labeling. Physicians should target emmetropia, and ensure that IOL centration is achieved. Care should be taken to remove viscoelastic from the eye at the close of surgery.

Some patients may experience visual disturbances and/or discomfort due to multifocality, especially under dim light conditions. As with other multifocal IOLs, visual symptoms may be significant enough that the patient will request explant of the multifocal IOL. Spectacle independence rates vary with all multifocal IOLs; as such, some patients may need glasses when reading small print or looking at small objects.

Clinical studies with the AcrySof® ReSTOR® lens indicated that posterior capsule opacification (PCO), when present, developed earlier into clinically significant PCO. Prior to surgery, physicians should provide prospective patients with a copy of the Patient Information Brochure available from Alcon for this product informing them of possible risks and benefits associated with the AcrySof® IQ ReSTOR® IOLs.

Studies have shown that color vision discrimination is not adversely affected in individuals with the AcrySof® Natural IOL and normal color vision. The effect on vision of the AcrySof® Natural IOL in subjects with hereditary color vision defects and acquired color vision defects secondary to ocular disease (e.g., glaucoma, diabetic retinopathy, chronic uveitis, and other retinal or optic nerve diseases) has not been studied. Do not resterilize; do not store over 45° C; use only sterile irrigating solutions such as BSS® or BSS PLUS® Sterile Intraocular Irrigating Solutions.

ATTENTION: Reference the Directions for Use labeling for a complete listing of indications, warnings and precautions.

ACRYSOF® SINGLE-PIECE MONOFOCAL INTRAOCULAR LENSES IMPORTANT PRODUCT INFORMATION

CAUTION: Federal law restricts this device to sale by or on the order of a physician.

INDICATIONS: AcrySof® single-piece monofocal intraocular lenses (IOLs) include the AcrySof® IQ Aspheric Natural IOL (Model SN60WF), AcrySof® UV-Absorbing Aspheric IOL (Model SA60WF), AcrySof® Natural IOL (Model SN60AT) and AcrySof® IOL (Model SA60AT). Each IOL is indicated for visual correction of aphakia in adult patients following cataract surgery. These IOLs are intended for replacement in the capsular bag.

WARNINGS/PRECAUTIONS: Careful preoperative evaluation and sound clinical judgment should be used by the surgeon to decide the risk/benefit ratio before implanting an IOL in a patient with any of the conditions described in the Directions for Use that accompany each IOL. Caution should be used prior to lens encapsulation to avoid lens decentration or dislocation. Viscoelastic should be removed from the eye at the close of surgery.

Studies have shown that color vision discrimination is not adversely affected in individuals with the AcrySof® Natural IOL (Model SN60AT) and normal color vision. The effect on vision of the AcrySof® Natural IOL in subjects with hereditary color vision defects and acquired color vision defects secondary to ocular disease (e.g. glaucoma, diabetic retinopathy, chronic uveitis, and other retinal or optic nerve diseases) has not been studied.

Do not resterilize. Do not store at temperatures over 45° C. Use only sterile irrigating solutions to rinse or soak IOLs.

ATTENTION: Refer to the Directions for Use labeling for each IOL for a complete list of indications, warnings and precautions.
