Cataract Surgery Lenses
Cataract surgery lenses are
known as pseudophakic intraocular lenses or
pseudophakic IOLs for short. These lenses replace the
natural crystalline lens, so the natural lens must be
surgically removed before implantation.
Most of the time, pseudophakic IOLs
are put in place because the natural lens has become
cloudy (i.e. cataract surgery), but more and more, they are
also being used purely for
vision correction purposes, even though the natural lens
is still clear.

Here's a closer look at
our preferred lenses:
Alcon ReSTOR Lens
In the past,
pseudophakic IOLs did not have the ability to provide
clear vision at both near and distance, so reading
glasses or bifocals were necessary for near vision following surgery.
However, in March 2005, the FDA approved
Alcon's ReSTOR lens, the first and only lens that uses apodized
diffractive technology to provide
patients with both near and distance vision. In clinical
trials, 80 percent of patients reported "never" wearing
reading glasses or bifocals following bilateral surgery
- the highest level of freedom from glasses ever
achieved in IOL clinical trials.
Both Dr. Hale and Dr.
Qamar attended the April 2005 meeting of the American
Society of Cataract and Refractive Surgery in
Washington, D.C., where investigators from around the
world presented results from ReSTOR trials. Both were
impressed with the success of the lens and believe it
will soon become a very popular choice, both for
cataract patients and as an alternative to laser vision
correction for select patients, especially those over 40
who would benefit from improved near and distance
Alcon AcrySof Lens
Since 1995, over 21
million AcrySof lenses have been implanted worldwide. In
essence, the AcrySof is the exact same lens as the
ReSTOR, but without the apodized diffractive technology
that boosts near vision.
Even though the ReSTOR
lens is a significant advancement, the AcrySof remains
an excellent alternative for those who are not good
ReSTOR candidates or whose insurance won't allow use of
advantage of AcrySof is its flexibility, which allows it
folded and then inserted into the eye through a small
incision that typically does not require stitches.
AcrySof unfolds gently, which allows us better control
than lenses of other materials. Surgery is safer and
more predictable, because the lens is easier to handle.
contains a UV absorber that provides protection equal or better than other UV blocking lenses and offers the
option of blue-light filtration, which may play a role
in reducing the development and progression of macular
AcrySof is an excellent ocular implant material
continues to grow. Recent studies show that patients
with AcrySof lenses experience less postoperative
complications than patients with silicone lenses.
In addition, fewer AcrySof patients require YAG laser
All told, we believe the
many advantages of AcrySof make it a safe choice
during surgery and an excellent performer over the
