AcrySof ReSTOR Fact Sheet
AcrySof ReSTOR is a breakthrough lens that uses apodized
diffractive technology to give patients a full range of vision-
near through distance- and greatly reduces their reliance
on reading glasses or bifocals. The AcrySof ReSTOR
intraocular lens (IOL) is an artificial lens used in cataract
surgery for patients with and without presbyopia. The unique
patented optic design results in highly-predictable visual
acuity results, meaning patients can read the font on items
such as prescription bottles, magazines, newspapers and computer
screens, while also providing the ability to see items at
a distance independent of reading glasses or bifocals. In
fact, clinical trials have demonstrated that four out of five
patients never needed to wear glasses or bifocals following
bilateral cataract surgery.
Clinical data demonstrates that AcrySof ReSTOR
IOL greatly reduces dependence on glasses or bifocals. 80
percent of patients in the FDA clinical study did not need
to wear glasses with AcrySof ReSTOR IOL, compared
to eight percent in the monofocal control group following
bilateral cataract surgery.
- Combined Visual Acuity: 84.3 percent of patients demonstrated
combined uncorrected vision without glasses of 20/25 or
better for distance and 20/32 or better for near.
- 85 percent of AcrySof ReSTOR patients achieved
20/40 or better binocular uncorrected intermediate vision.
- In most states, 20/40 vision allows individuals to
pass the visual requirements for the driver’s
license test without glasses or contact lenses.
The AcrySof ReSTOR IOL is made of the same highly-biocompatible
acrylic material as Alcon’s market-leading AcrySof family
of intraocular lenses, which have been implanted in more than
21 million human eyes since 1991.
AcrySof ReSTOR IOL uses a combination of three
complementary technologies: apodization, diffraction and refraction.
Its unique apodized diffractive optic design provides the
ability to focus light correctly on the retina for images
at various distances without mechanical movement of the lens.
- Apodization is a gradual reduction or blending of the
diffractive step heights.
- This unique technology optimally manages light energy
delivered to the retina because it distributes the appropriate
amount of light to near and distant focal points, regardless
of the lighting situation.
- Apodized diffractive optics are designed to improve image
quality while minimizing visual disturbances. The result
is an increased range of quality vision that delivers a
high level of spectacle freedom.
