Q: What
is Laser Vision Correction?
A: Laser
Vision Correction is a precise computerized procedure
that uses the VISX Star laser to correct nearsightedness,
farsightedness, and astigmatism. During the treatment,
the lasers cool beam of ultraviolet light removes
a small amount of tissue, usually less than the thickness
of a human hair. Short pulses of this cool beam laser
light change the curvature of the cornea, allowing
images to be more sharply focused.
Q: What are Nearsightedness, Farsightedness, and
Astigmatism?
A: Nearsightedness
occurs when the curve at the front portion of the
eye, known as the cornea, is too steep, resulting
in blurred images in the distance. In a normal eye,
the cornea and the lens of the eye focus light to
form an image on the back surface of the eye, known
as the retina. In a nearsighted eye, the eye focuses
or refracts light too much, causing images of distant
objects to form in front of the retina and appear
blurry; with farsightedness, the opposite is true
weaker focusing power causes the image to theoretically
focus behind the retina, also making them appear blurry.
Astigmatism results in blurred vision as the result
of irregular curvature of the cornea.
Q: Am I a candidate for Laser Vision Correction?
A: Candidates
for Laser Vision Correction should be 18 years or
older with stable vision, healthy eyes, and a refractive
vision problem within the range of effective treatment.
You will need an initial evaluation followed by a comprehensive exam to
help you and your doctor decide what procedure is
right for you.
Q: What are the real benefits of Laser Vision Correction?
A: Laser
vision correction is the modern alternative to glasses
or contact lenses. The goal of LVC is to reduce or
eliminate your dependence on contact lenses and glasses.
Q: I wear bifocals now, and my doctor says that
Ill still need to wear reading glasses even
if I have LASIK done. Why is this?
A: Most
people in their 40s or older will need reading glasses
if their eyes are corrected for distance because the
eyes lens loses flexibility as we age. This
condition, called presbyopia, cannot currently be
treated by surgical methods.
Some patients in this age group select monovision,
such as is done with contact lenses. This option allows
patients to use one of their eyes for distance and
the other to see up close. Although monovision proves
to be satisfactory for some patients, many are not
comfortable with this arrangement. Patients need to
discuss the options with their physicians.
Q: If Im corrected for distance, will I lose
ability to see well up close?
A: If you
have LASIK done to correct your distance vision, you
can expect to have very clear overall vision. However,
images close to you may not appear as clear after
having LASIK if you are over 40 years of age.
Q: Does insurance cover this surgery?
A: Although
LASIK is not considered a cosmetic procedure, it is
considered an elective surgery. Such surgeries are
covered in many European and Asian countries. However,
most United States, Canadian, and Latin American insurance
policies will not cover the procedure, nor will Medicare
usually cover it. If you reside in the U.S., you should
check with your insurance company to see if your policy
offers partial or full coverage. In many cases, the
cost of the procedure can be covered by medical flex
plans or medical cafeteria plans that allow pretax
dollars to be set aside for medical expenses. You
should check with your employer to see if your company
offers this type of benefit. It is possible that the
cost of LASIK may be deducted from your U.S. federal
income taxes. You should check with your accountant
to see if you can take LASIK as a deductible health
expense.

Q: Can I have both eyes done with LASIK at the
same time?
A: You
can have bilateral simultaneous LASIK (both eyes done
at the same time), but the choice to do so depends
on the surgeons approach and your requirements.
Some surgeons prefer to wait a few days to several
weeks between eyes in order to evaluate the results
of the first eye. While this practice affords the
patient an opportunity to see clearly with at least
one eye before the other is done, it somewhat inconveniences
the patient. Some surgeons will do both eyes on the
same day in order not to inconvenience the patient;
however, others maintain that there may be additional
risks associated with bilateral surgery. Patients
should discuss their options with their ophthalmologist.
Q: If I have one eye done at a time, what will
my vision be like in between the first and second
surgeries?
A: There
are a number of different options to help patients
deal with their vision between procedures. Some patients
who do not have bilateral surgery will begin wearing
a contact lens in the eye that has not undergone surgery.
This practice gives them an opportunity to use their
two eyes simultaneously. However, the contact lens
will need to be removed at least five days prior to
the second surgery.
Others function by using the operated eye immediately
without the use of a contact lens in the opposite
eye. This solution may work for nearsighted patients
with a refractive error of fewer than six diopters.
A patient with a refractive error above six diopters
who does not wear a contact lens may be unable to
use both eyes together due to the large difference
in refractive error between the eyes. Removing one
lens from a pair of glasses is usually not useful.
Doing so could cause double vision and eyestrain.
Q: Can I play sports after LASIK surgery?
A: You
can resume most normal activities immediately after
surgery. However, for at least two weeks you will
need to avoid activities that would cause perspiration
to run into the eyes. You should wear safety glasses
while playing contact sports whether or not you have
had surgery. But if you do not routinely wear safety
glasses, your surgeon may recommend wearing them for
at least one month after LASIK. You will also need
to avoid such activities as contact sports and swimming
for several weeks. It is important to talk specifically
with your doctor about limitations on activities after
LASIK.
Q: How long will it take before I can see well,
and how long will it take before I have my best vision?
A: Fast
visual recovery characterizes this operation. Most
patients achieve good vision the day of the surgery
and find that their eyes feel fairly normal within
a day. However, vision can continue to improve, and
best vision can still take two to three months to
occur. If necessary, adjustments to the surgery (called
enhancements) can be done.
Q: Will I need to wear glasses once my eyes have healed?
A: Most
patients who have LASIK do not wear classes for their
daily activities. However, patients may need to wear
reading glasses if they are over the age of 40. This
is caused by the normal aging of the eye known as
presbyopia. This condition occurs with or without
LASIK. Some patients may need a minimal prescription
for some activities such as night driving.
Q: How safe is the LASIK procedure?
A: Most
studies show that LASIK produces minimal risk of serious
complications. However, LASIK is a surgical procedure
done on a delicate part of the eye, and complications
can occur. Risks and complications will be further
discussed with you during your LASIK consultation.
Q: Are the results achieved from LASIK permanent?
A: The
effects of LASIK are permanent. The effects of LASIK
do not wear off. But it is important to realize that
a persons eye can change internally. That is
why many surgeons recommend having the procedure done
after the major eye changes have occurred in ones
life. For instance, LASIK is not recommend on children
because their eyes change a great deal. They would
need the vision fine-tuned in a few years. If the
procedure is performed after the age of 18, the chance
of long-term stable correction is more likely. Even
the eyes of patients over the age of 18 can still
be changing.
Therefore, we recommend a good conversation with your
surgeon so they can review the changes you have had
and help you make a decision whether or not you should
wait until the changes have slowed down. Patients
should also note that while results are usually stable,
they can be modified by enhancement procedures
procedures performed after the initial one
if necessary.
Q: If I have LASIK and my vision changes later in
life, can it be redone?
A: Retreatment
may a viable solution to vision changes later in life,
and other treatment options exist. You would need
to see your ophthalmologist to determine the cause
of the change and to determine which option is best
for you.
Q: How
long will the LASIK procedure take?
A: The
whole procedure takes about 10 to 15 minutes for two
eyes, including creating the flap and performing the
laser under the flap.
Q: Can I drive immediately after having LASIK?
A: Patients
may experience some discomfort and/or blurred vision
for a few hours after surgery, and most patients receive
a sedative prior to surgery. Therefore, you cannot
drive home after undergoing the procedure, and you
should plan not to drive for at least twenty-four
hours.
Q: What type of anesthetic is used for LASIK?
A: The
procedure is done with a topical anesthetic (eye drops)
to numb the eye. Patients may be given a small amount
of oral sedative to help them relax.
Q: Does the LASIK procedure hurt?
A: Patients
are given a topical anesthetic (eye drops) to numb
the eye, so they experience no pain. When the surgeon
applies the vacuum ring, the patient experiences a
sensation of pressure just before his or her vision
fades for a few seconds. The microkeratome
the instrument the surgeon uses to create the flap
and the laser do not cause any pain or discomfort.
For several hours after the procedure, many patients
describe a mild burning sensation, such as after opening
the eyes while swimming in chlorinated water. After
the first few hours, this uncomfortable feeling usually
subsides.
Q: How long will I be out of work after having LASIK?
A: It depends
on your occupation. Certain jobs that require intense
clarity of vision (dentistry and surgery, for example)
may be difficult to perform for one or two days. Most
patients can return to work the next day, assuming
their vision is adequate for their job. However, some
people may feel fatigued for a day or so following
surgery.
Q: Is LASIK investigational?
A: No.
LASIK has been performed outside of the United States
for approximately ten years and in U.S. clinical trials
with excellent results since 1991. It is now the most
commonly performed refractive procedure in the United
States. Long-term studies indicate that LASIK is safe
and effective. LASIK is outside the scope of
current approved labeling in the United States,
and the FDA considers the decision to conduct LASIK
as the practice-of-medicine. This means
that physicians can perform LASIK should the physician
and the patient make the joint decision to do so.
Q: Why is LASIK performed as a practice-of-medicine
in the United States?
A: The
FDA approves drugs and devices. The FDA has approved
the use of microkeratome. It has also approved the
excimer laser for surface treatment of nearsightedness
(myopia), farsightedness (hyperopia), and astigmatism
in the United States. PRK underwent the FDA clinical
trials. However, the FDA has not approved the use
of these two instruments in the same procedure. Here
is why: Laser manufacturers would have to repeat the
expensive and time-consuming approval process with
LASIK that was already completed and approved for
PRK. Since the approved lasers and microkeratomes
have proven safe and effective, surgeons are allowed
to perform LASIK if both the surgeon and patient believe
that this procedure best serves the patient. Therefore,
most manufacturers have opted not to undergo the process.
Nevertheless, some manufacturers are going through
the effort of working with the FDA to put LASIK in
the specific labeling for excimer laser so that it
would not be considered an off-label procedure.
Q: Is LASIK an off-label use of the excimer laser?
A: Since
VISX received FDA approval for its STAR S2 Excimer
Laser system for LASIK for the treatment of nearsightedness
up to 14.0 diopters with or without up to-5.0
diopters of astigmatism, LASIK is no longer considered
off-label for this application. LASIK correction of
hyperopia, however, is still an off-label use. The
use of devices during a procedure deemed a practice-of-medicine
is called an off-label use of these devices.
Because the approved lasers and microkeratomes have
proven safe and effective in other procedures, ophthalmologists
can use them off-label if it is in their patients
best interest to do so.
Q: When LASIK is an off-label use, why do surgeons
opt to do this procedure?
A: LASIK
has significant advantages over other methods for
many patients. The safety and accuracy of LASIK equals
or exceeds that of PRK. Because of the wide range
of correction and the rapid visual recovery associated
with LASIK, it is already the most common refractive
surgical procedure in the United States.
Q: What results can I expect from LASIK?
A: LASIK
improves the uncorrected vision ones
visual capacity while not wearing corrective lenses
in most patients who have the procedure. Almost
all patients can expect to achieve 20/40 vision, which
most states and provinces consider good enough to
drive without having to wear contacts or glasses,
and many can expect to achieve 20/20 vision or better.
However, there are no guarantees that you will have
perfect vision. People who are most satisfied with
the results of laser correction clearly understand
the potential risks and complications and possess
realistic expectations of what their vision will be
like after surgery.
Q: Will my eyes look different after LASIK?
A: No.
Your eyes will look exactly the same.
Q: What does Laser Vision Correction cost?
A: When
compared to non-surgical alternatives, refractive
surgery is surprisingly cost effective. Ask our staff
to discuss our charges and all finance options available
to you.
Q: Is Laser Vision Correction affordable for me?
A: YES!
The affordability of laser vision correction has never
been greater. First, consider the cost of replacing
your eyeglass frames and lenses or the repetitive
costs of disposable contact lenses. With laser vision
correction you can receive the greatest value: clear
vision without glasses or contact lenses! Ask about
our many affordable financing options that are available.

more.
Q: How is LASIK done?
A: LASIK
combines the use of two technologies: the microkeratome
and the excimer laser. The microkeratome is a device
that has been used for many years in corneal eye surgery
to create a flap in the cornea. Once the flap is made
it is folded back to allow the excimer laser to treat
in the corneal bed. The benefits of this procedure
include minimal pain, rapid visual rehabilitation,
and less change due to healing (regression).
Q: What does the term LASIK mean?
A: LASIK
is the acronym for laser in situ keratomileusis, sometimes
referred to as laser assisted in keratomileusis. The
name refers to the use of a laser to reshape the cornea
without invading the adjacent cell layers. In situ
is Greek for in the natural or normal place.
Medically, in situ means confined to the site of origin
without invasion of neighboring tissues. Kerato is
the Greek word for cornea and mileusis means to
shape.
Q: How long has LASIK been performed?
A: LASIK
has been performed internationally for approximately
10 years. It was first performed in clinical trials
in the U.S. in 1991. It is important to note that
major components of the procedure have a long history.
Ophthalmologists have been reshaping the cornea for
over 50 years, creating a protective layer of tissue
for over 35 years, and using the excimer laser since
the 1980s.
Q: Why is LASIK considered an advancement in refractive
surgery?
A: LASIK
combines the precision of the excimer laser that is
used in PRK (Photo Refractive Keratectomy) surgeries
with the flap technique that characterizes ALK.
Q: Whom can LASIK benefit?
A: LASIK
can benefit a great number of people with myopia,
hyperopia, and astigmatism. Candidates should have
a strong desire to be less dependent on corrective
lenses and be willing to accept the risks of surgery.
Q: What can I expect on the day of my Laser Vision
Correction procedure?
A: Laser
vision correction is the modern alternative to glasses
or contact lenses. The goal of LVC is to reduce or
eliminate your dependence on contact lenses and glasses.
Once you become accustomed to the sound of the laser,
anesthetic drops will be placed in your eye to numb
it. In the laser room, you will be seated in a reclining
chair, the physician will position your head under
the laser, and a retainer will be placed between your
eyelids to gently hold them open during the treatment.
Access to the cornea will be performed. Once completed,
you will be asked to focus on a blinking red light
while the laser removes microscopic amounts of tissue
from the cornea. The laser will treat your eye for
less than one minute and your total time in the laser
area will be about 30 minutes. After your laser treatment
is complete, some drops and a protective bandage or
lens will be placed on your eye for protection and
comfort. While the actual procedure is painless due
to the numbing of the eye drops, you will experience
some slight irritation during the immediate post-operative
period.
Q: How do I choose a surgeon?
A: Be an
informed consumer. Ask questions regarding the surgeons
background, experience, and the outcomes they have
had in delivering vision correction. Ask your optometrist
for a recommendation. Attend informational seminars
and complimentary evaluations. Ask the surgeon questions
specific to your visual needs and expectations. The
surgeons at MSEILASIK Vision Centerhave
extensive experience in delivering results consistent
with your needs. As leaders in the field, our surgeons
are involved in clinical investigation of advancements
such as hyperopia (farsightedness) treatments.
Q: What are the risks associated with Laser Vision
Correction?
A: The
most common side effects during the immediate post-operative
period are pain, light sensitivity, blurred vision
during healing, inadequate correction, over correction,
glare, haze, star burst, and induced astigmatism.
These side effects usually diminish as the eye heals.
While significant complications are very rare, the
following are some of the problems that can occur.
These include infection, intraoperative complications,
inadequate healing, persistent irregular astigmatism,
and unstable vision. This is not a complete list of
side effects or complications. It is very important
to discuss the potential risks with your doctor prior
to consenting to surgery.
