A revolutionary advance in
cataract surgery has been made. 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 or 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 cataract surgery in both eyes.
AcrySof ReSTOR is a
foldable IOL and represents breakthrough technology
because of its unique, patented optic design, which
allows patients to experience the highest level of
freedom from glasses ever achieved in IOL clinical
Clinical data demonstrates that
AcrySof ReSTOR IOL greatly reduces dependence on
glasses or bifocals.
80% of patients in the FDA
clinical study did not need to wear glasses with
AcrySof ReSTOR IOL, compared to 8% in the monofocal
control group following cataract surgery in both eyes.
Combined Visual Acuity: 84.3% of
patients demonstrated combined uncorrected vision
without glasses of 20/25 or better for distance and
20/32 or better for near.
85% of Acrysof ReSTOR patients
achieved 20/40 or better binocular uncorrected vision.
In most states, 20/40 vision
allows individuals to pass the visual requirements for
the driver’s license test without glasses or contact
Acrysof ReSTO IOL uses a
combination of three complementary technologies:
Apodization: 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.
Diffraction: The spreading of
light. In an optical system, light can be diffracted
to form multiple focal points or images.
Refraction: The deflection of a
ray of light when it passes from one medium into
another of different optical density.
The Acysof 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 that 21 million human eyes since 1991.
The AcrySof ReSTOR IOL
received approval by the U.S. Food and Drug
Administration in March 2005. Clinical trials were
conducted in the United States and Europe
to establish the safety and effectiveness of the AcrySof
ReSTOR IOL. A total of 566 patients received the
AcrySof ReSTOR lens in clinical trials and had a mean
age of 68 years.
Since its introduction
outside the U.S. in 2003, more than
11,000 AcrySof ReSTOR IOLs have been implanted in
patients by more than 1,000 surgeons in Europe and
other countries. More than 500 ophthalmic surgeons
outside of the U.S. have been trained to implant
the AcySof ReSTOR lens and thousands of lenses have
already been successfully implanted.
A cataract is a “clouding”
of the eye’s natural lens, which results in blurred or
defocused vision. According to a recent article
published in the Archives of Ophthalmology, more than 20
million adults in the U.S. have developed
cataracts making it the number one cause of poor vision
in the United States. While not all cataracts require
surgery, nearly 3 million cataract procedures are
performed annually in the U.S. Cataracts cannot be
prevented and are the leading cause of treatable
blindness worldwide. According to the National Eye
Institute, the number of Americans with cataracts is
expected to rise to over 30 million people by the year
The Eye Clinic is among
the first medical groups in the United
States to receive the new lens.
