Alcon AcrySof ReSTOR Intraocular Lens Implant
Entirely Unique:
The ReSTOR Lens Design
The ReSTOR lens is like two lenses in one. One refractive lens
is for distance, and the other one, a diffractive lens, is
for near. ReSTOR is not dependent on the movement of the lens. Instead,
it has a unique apodized diffractive optic that is new to IOL design.
This optical design of the lens distributes light between near vision
and distant vision to accommodate vision at a range of distances. While
a perfect intraocular lens has yet to be developed, the FDA
results for the ReSTOR lens have been better than all previous multifocal
implants.
Apodized Diffractive
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
through distance vision. Refractive involves the redirection of light
passing through the lens, to focus on the retina. 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.
Breakthrough Technology
The AcrySof ReSTOR IOL represents breakthrough technology because it
treats the refractive problem of presbyopia. It delivers consistent
high-quality accommodative-like vision across the entire visual
spectrum. This is due to its unique, proprietary and innovative optics.
The ReSTOR lens uses a new strategy for collecting and distributing
light that doesn't rely on the ciliary muscle, the muscle that controls
the flexing of the inside lens, which looses its effectiveness with
age.
Other accommodative-type intraocular lenses produce vision at various
ranges by depending on the action of the eye's muscles to produce
accommodation. However, the ReSTOR lens provides different ranges of
vision based on a lens configuration that enables specific distribution
of light in response to how wide or small the eye's pupil might be.
This light distribution design is called apodized diffractive optics.
Highest Quality Results
Previous attempts using various multifocal lenses often resulted in
haloes and significantly reduced contrast sensitivity in low
light conditions. These issues are no longer a problem with the ReSTOR
lens. As well, unlike the blended vision monofocal implant option; there
is no loss of depth perception. Reading ability, even for fine print,
is markedly improved with the ReSTOR.
Medicare Approved!
Medicare has announced revisions to some of its payment guidelines,
allowing patients covered for cataract surgery to choose the
ReSTOR lens at an added fee. Previous Medicare payment rules did not
allow patients to choose this lens, which is significant since
the lens was specifically designed for this age group.
The ReSTOR lens and the care associated with the surgery to implant
it treats the non-covered refractive diagnosis of presbyopia.
For the first time, Medicare is now allowing patients to choose this
elective refractive service. Patients with cataracts will still have
their basic surgery covered by Medicare and/or insurance, plus they
may elect to pay out of pocket for the upgrade of the ReSTOR lens and
presbyopia treatment.
Refractive lens exchange, surgery patients without cataract who wish
to be independent of glasses would be responsible for the whole
fee as usual.
Alcon's AcrySof ReSTOR Lens Is FDA-Approved:
This new artificial lens, which often can restore sight at near, intermediate,
and distant ranges following cataract surgery, has received
United States Food and Drug Administration approval. The clinical studies
supporting its approval showed that 80 percent of patients who received
the AcrySof ReSTOR lens did not use glasses for any activities after
cataract surgery.
Although the ReSTOR implant is new to the United States, it has had
the CE Mark in Europe (highest certification in Europe, a designation
similar to UL – underwriters labs - in the United States) and
there are many thousands already implanted worldwide.
