Alcon AcrySof ReSTOR Intraocular Lens Implant
Meeting the Challenge of Presbyopia:
The ability to focus at various distances is called 'accommodation',
and is the normal condition of a youthful natural lens. However,
as we age, this lens becomes more rigid and our ability to
accommodate diminishes, usually starting around the age of forty. This
inability to accommodate is called presbyopia. Presbyopia is the reason
that reading glasses or bifocals are required as we age.
Aging also causes the eye's natural lens to become more opaque, which
scatters light and creates cloudy vision. The opaque lens is
called a cataract. More than half of Americans 65 and older
have cataracts. Traditionally, when a cataract develops, the
human lens is replaced with an artificial lens inside the eye. Our standard
preferred lens implant allows perfect vision without glasses for one
distance only, usually for far distance. Glasses are still needed for
close up vision.
Monovision, achieved through blended vision, where one eye is focused
for distance and the other eye for intermediate near, is sometimes
a good compromise for average daily activities but still requires
prescription glasses for fine visual tasks.
Surgical techniques using the ReSTOR lens can fix far-sightedness and
near-sightedness. Techniques using the ReSTOR lens also can
correct presbyopia in a pre-cataract condition with a procedure
called refractive lens exchange, for those who do not yet have
cataracts and are highly motivated to be glasses free.
For the first time in the history of ophthalmology, 80% of patients
who choose the ReSTOR lens can be completely independent of
glasses for all daily activities. Near, intermediate and distance
vision are all corrected in cataract patients with the ReSTOR
intraocular lens with apodized diffractive optics.
If you are interested in seeing your best without glasses please contact
East Valley Ophthalmology so that we can evaluate the appropriateness
of this technology for you. Together, we can further discuss
the benefits, risks and costs.
