Presbyopia ( loss of accommodative amplitude with
aging ) is a disabling condition not fully correctable with spectacles.
The development of the Multifocal multifocal implant ,
released 12 months ago has allowed thousands of patients to be free of
spectacles and enjoy good reading vision. It effectiveness depends on
meticulous preoperative biometry with a laser interferometer and careful
patient selection as well as faultless surgical technique.
Its has the advantage in less visual distortion and
halo at night and being effective in all light conditions unlike its
competitor refractive technology multifocal lenses such as the Rezoom
or Restor/Technis Multifocal .
Multifocal lenses are only available to those
ophthalmologists that have undergone special training in their use. The
require higher standards of pre-operative biometry and meticulous
surgical technique. Alcon has certified Berwick Surgicentre as a “Multiifocal
Lens Site” on the basis of training and quality of facility.
I one of the top 3 implanters of Multifocal lenses
in Victoria. To date all reports are of a high satisfaction rate
and no incidences to date of lenses requiring exchange or of laser
vision correction postoperatively
Multifocal vs. Monofocal:
The Difference
If you believe you may have a cataract, don't worry. You're not alone.
Every year, thousands of Australians have cataract surgery, and many are
pleasantly surprised by the improvement in their vision.
Monofocal IOL
-
Offers vision at
one set distance, usually far.
-
Good vision when
you go to a ballgame or read road signs.
-
You will probably
need glasses for reading or crafts.
Multifocal IOL
-
Offers good far
vision like a monofocal IOL.
-
Offers intermediate
vision as good or better than a monofocal IOL (from two to five
feet).
-
Also offers a good
near vision with less dependence on glasses or bifocals.
-
If you play
golf you may be able to see where your drive lands, sink your
putt and write down the score - all without glasses.
-
When shopping,
you may be able to read the aisle signs and package labels, and
count your change - all without glasses.
How the Works
When you compare the multifocal IOL with a monofocal lens (see
photos below), you can see the has concentric rings instead of
a flat surface. Many patients with monofocal IOLs can focus on distant
objects such as mountains. But objects at intermediate distances, such
as people at a few feet away, may be out of focus. So, many people with
monofocal IOLs need bifocals or reading glasses.
Results with the
Some
people who receive either monofocal IOLs or multifocal IOLs report halos
or glare at night. These effects are more common with multifocal than
monofocal, although individual results may vary. Only your eye care
practitioner knows what kind of results you can expect, but scientific
studies have shown that 89% of people who receive the are able
to read small print without glasses, 89% are free from severe problems
with glare and 89% are free of severe difficulty with halos.1
Quality of Life with the Many of today's cataract patients are alert and
fit, prefer an active lifestyle, and have high expectations for their
vision . The is well qualified to meet these
expectations as shown by a survey of people with IOLs and
people with monofocal IOLs.2
