Will I have 20/20 vision
following laser vision correction?
The goal of any refractive surgical procedure
is to reduce your dependence on corrective
lenses. However, we cannot guarantee you will
have 20/20 vision as a result. Our commitment
to you is that we will not perform laser vision
correction on you or anyone we feel does not
have a good possibility of achieving independence
from glasses and contacts. The vast majority
of our patients are extremely happy with their
results and can do most activities without
dependence on corrective lenses after laser
vision correction.

Is laser vision correction
safe?
There are possible risks with any surgical
procedure. Serious complications with LASIK
are extremely rare. The chance of having a
vision-reducing complication from LASIK has
been documented in clinical studies to be
less than one percent. Many of the risks and
complications associated with this procedure
can be reduced or eliminated through careful
patient selection and thorough pre-operative
testing using the latest diagnostic technology.
After laser vision correction, you may experience
some visual side effects. These are usually
mild and most often diminish over a few days
to a few weeks. But there is a slight chance
that some of these side effects won't go away
completely, such as feelings of dryness, glare
and halos. If after a thorough examination
we decide you are a good candidate for laser
vision correction, you will be given additional
information about the procedure that will
allow you to make an informed decision about
whether to proceed. Be sure you have all your
questions answered to your satisfaction.

What is the IntraLase
method used in iLASIK?
The IntraLase Method is a 100% blade-free
technique used to perform the critical first
step in the LASIK procedure: creating the
corneal flap. The IntraLase Method uses tiny,
rapid pulses of laser light to create your
corneal flap-instead of using a microkeratome-during
the first step of LASIK. A microkeratome is
essentially a hand-held steel blade that moves
across the cornea to create a flap. As it
cuts, the blade oscillates back and forth,
which can leave an irregular surface after
the flap is lifted. This can affect the quality
of your postoperative vision. Because of the
unique way in which the IntraLase Method creates
a precisely positioned layer of bubbles just
beneath the surface of your eye, it creates
a smooth even surface after your flap is lifted.
With the IntraLase Method, a blade never touches
your eye. This customized approach leaves
the patient with better vision. The creation
of the flap itself takes only about 15-30
seconds per eye.

What about nighttime side-effects?
You have probably seen news stories about
people having difficulty driving at night
after refractive surgery. Nighttime side-effects
may include halos, starbursts, and glare around
lights and blurry vision. Some of these can
be caused higher order aberrations (imperfections).
These effects usually diminish as the eye
heals in the first three to six months. With
Customvue LASIK, four times as many patients
were satisfied with their night vision than
with glasses or contact lenses! Another possible
cause of nighttime side-effects is pupil size.
At night, the pupil expands to let in more
light. Light coming through the peripheral
cornea may be out of focus if the pupil opens
beyond the laser treatment area. This is why
some patients are not good candidates for
LASIK if they have very large pupils. However,
our advanced laser technology has expanded
treatment zones to the widest optical zone
therefore patients that were at one time not
candidates for LASIK because they had large
pupils, can now be treated.
-
Does LASIK cause dry eye?
Following a LASIK procedure, every patient
has temporary dry eye, which can be treated
most often with artificial tears. This dry
eye sensation usually clears up in eight to
12 weeks except in rare cases, where it may
take longer. Patients with pre-existing dry
eye may not be good candidates for LASIK,
but may be candidates for PRK or LASEK. If
you have dry eye, you should discuss it with
your doctor at your pre-op examination. Tests
can often diagnose dry eye but it is still
somewhat difficult to predict who will experience
significant dry eye following LASIK. A thorough
evaluation of your current medications, medical
history and work environment should all be
taken into account.
-
Will it hurt?
There is no pain during any of the laser vision
procedures since anesthetic eye drops numb
your eyes, although some patients may experience
mild discomfort or a pressure sensation during
their procedure. After LASIK, you might experience
mild irritation for a few days. An over-the-counter
pain reliever or use of artificial tears will
generally take care of this discomfort. PRK
and LASEK patients experience more post-operative
discomfort for three to five days while the
epithelium heals.
-
How long does the procedure
take?
Once in the laser room your eyes will be cleaned
and prepared for surgery. The surgery itself
usually only takes five minutes or so per
eye. The excimer laser is being applied to
your eye for just a few seconds. You will
need to show up a least half an hour before
your procedure so that we can get you relaxed
and ready.
-
Do I have to go without
my contacts before having laser vision correction?
If you are wearing hard or gas permeable contacts,
it's important that you remove them at least
three weeks prior to your exam. Soft lenses
should be out for at least two weeks before
your exam. Soft toric lenses may need to be
out longer. Your doctor will advise you how
long you need to be out of your contacts prior
to your exam and prior to your surgery.
-
How old do I have to be
for laser vision correction?
You need to be over 18 years of age, and your
glasses or contact lens prescription should
not have changed in the last year. If your
eye is still changing from year to year, you
should not have the procedure until the cornea
is stable.
-
Can I have laser vision
correction while I am pregnant or trying to
conceive?
Pregnancy can affect your vision, therefore
if you are pregnant or trying to conceive,
you should not have laser vision correction.
You should wait several months after your
pregnancy or after you finish nursing before
having laser vision correction.
-
How long will the results
of the surgery last?
Laser vision correction is considered to be
permanent. However, your eyes can still change
as you age which may cause a need for glasses
or contacts or additional vision correction
procedures in the future. As people reach
their early forties, they develop presbyopia
and begin to need reading glasses. If you're
over 40, you may want to consider monovision.
-
If I choose to have monovision,
does that mean I'll never need reading glasses?
Not necessarily. The effects of presbyopia
continue to worsen as you get older, whether
or not you have monovision. At some point
in time, reading glasses or another vision
correction procedure may become necessary.
The benefit to having monovision is that there
won't be a complete dependence on glasses
for close vision. Many who have monovision
are able to see well enough both at a distance
and near to do things at any age without corrective
lenses.
