Clear vision results from light rays passing
through the cornea, the lens and then directly onto the
retina. From the retina the image is transferred to the
brain and this is how we see. Each individual's eye and
cornea have a unique shape. If the curvature of your
cornea does not allow light rays to focus directly on the
retina, then you have a refractive error. Refractive
errors such as nearsightedness, farsightedness and astigmatism
can be corrected by wearing glasses or contact lenses or by
changing the shape of the cornea through Laser Vision
Correction. [top of page]
What
is Myopia?
Myopia, or nearsightedness, is an inherited condition in
which the light rays entering the eye focus in front of the
retina instead of directly on the retina. This occurs because
the cornea, or front of the eye, is too steeply curved or the
eye itself is too long. When a patient has myopia, near
objects can be seen clearly, while distant objects appear
blurry or even indistinguishable. Myopia, which affects 25% of
the world’s population, usually begins in childhood and
stabilizes in the late teens or early twenties. [top

What
is Hyperopia?
The cornea of a farsighted person is too flat for
the rest of their eye and thus the light rays entering the eye
focus an image behind the retina instead of directly on the
retina. A farsighted person may see far objects more
clearly than near objects.
We correct farsightedness by steepening the
cornea, with Laser Vision Correction, and thus re-focusing the
light rays directly on the cornea. [top
of page]
What is Astigmatism?
Astigmatism is a condition caused by an uneven
curvature of the cornea. This irregular steepening warps the
light rays entering the eye, making it difficult for
astigmatic patients to focus clearly on any object. [top

What is Refractive Surgery ?
Refractive surgery generally refers to any surgical
procedure that changes the refractive power of the cornea, or
the front part of the eye. At first, incisions were made on
the cornea to correct nearsightedness by flattening the
curvature of the cornea. In recent years, major advances in
laser technology have made laser vision correction a safe and
very accurate procedure. [top

What
is laser vision correction?
Laser vision correction is an outpatient procedure
that uses a cool beam of light to gently reshape the surface
of the eye, thereby correcting or greatly improving vision. [top
of page]
What are the overall benefits of
laser vision correction?
Laser vision correction allows nearsighted,
farsighted, and astigmatic people to end or greatly reduce
their dependency on glasses and contact lenses. [top
of page]
Is LASIK safe?
Yes. Over two million people worldwide have
successfully undergone laser vision correction with excellent
results. The U.S. FDA has recognized laser vision correction
for nearsightedness, farsightedness, and astigmatism, and
found the treatment safe and effective for eligible patients.

What can I expect before the
procedure?
An optometrist or ophthalmologist will conduct a
comprehensive eye exam to determine your candidacy. Other
diagnostic tests will also be conducted to ensure good
results. [top of page]
What can I expect on the day of the procedure?
The actual laser treatment takes less than one
minute and the entire procedure may last 15 to 20 minutes.
Your visit should be complete in about an hour. [top
of page]
What happens during the LASIK
procedure?
You will relax in a reclining chair and anesthetic
drops will be placed in your eye. Then, your eye doctor will
position your head under the laser and a retainer will be
placed to hold your eyelids open during treatment. The laser
procedure will last about a minute following the flap
creation. After the procedure, you will relax in a chair for a
few minutes and the doctor will examine you. Then you may go
home.

please attend one of our free consultations. [top

What are the risks?
There are risks associated with any clinical
procedure. However, because the laser uses a cool beam of
light that is computer controlled, there is little room for
error. In a recent study, all patients experienced better
uncorrected vision following laser vision correction. [top

Is financing available?
There is financing available through The M-Lend or through outside providers of patient
financing. Our Refractive Coordinator will be happy to
discuss financing details when you are evaluated for the
procedure. We have a section on this website which addresses
patient financing. [top of page]
Is LASIK painful?
It is not painful. Slight eye pressure may be
felt during the procedure. It is generally performed with the
patient under a light sedative for relaxation. It has not been
necessary to provide any type of pain medication after the
procedure. [top of page]
What are some benefits of Refractive Surgery?
People decide to have refractive surgery for many
reasons. These surgery patients say they like the independent,
secure feeling they receive when they no longer have to rely
on corrective lenses to function. Other benefits of this
surgery include the comfort and convenience patients derive
from not wearing corrective lenses, enhanced physical
appearance, better peripheral vision, and increased
self-esteem. This surgery enables patients to see clearly when
they jog, golf, swim, scuba dive, ski, and participate in
other sports. Additionally, it has proven to be a
cost-effective alternative to glasses and contact lenses. The
estimated lifetime cost of contact lenses is $12,000, while
the estimated lifetime cost of spectacles is $7,000.

Am I eligible for Refractive
Surgery?
It depends on your age, your degree of vision
correction needed, and the general health of your eyes. You
must have a prescription that has been stable for at least 12
months and must be 18 years of age or older. There is no upper
age limit; even seniors may be eligible. You should not
undergo refractive surgery if you are pregnant or nursing;
have signs of a corneal disease; have an auto-immune or
immunodeficiency disease or have a previous corneal injury or
scar near the corneal center. One of the best ways
to help determine if you are a candidate for refractive
surgery is to schedule a free consultation. [top

How successful is Refractive
Surgery?
The American Academy of Ophthalmology recently
published a report stating, "A wealth of clinical and
laboratory data have now defined a relative level of safety
and effectiveness for the procedure." In fact, 96% of the
patients who have this surgery achieve 20/40 vision (legal
driving vision) or better after surgery and any necessary
enhancement procedures. [top
of page]
Will my vision regress over time?
Probably not. Nearsightedness usually begins in
childhood, worsens during adolescence, and stabilizes during
the twenties. Because most people experience very few
prescription changes in their distance vision after reaching
their mid-to-late twenties, it would be highly unusual to
experience visual regression years after surgery. If you
wanted to have surgery and your vision was changing
significantly, we would not perform the surgery until your
prescription was stable for at least one year.If you regress
at all, it would be far more likely to occur during the 3-6
month stabilization period following surgery. You might then
undergo an enhancement at no cost to "fine-tune"
your vision. [top of page]
What are the complications and
side effects?
As with any type of eye surgery, complications are
possible but highly unlikely. These
complications generally involve the corneal flap. If the eye
has not been held firmly by the suction ring, a thin flap or
free cap may occur. It may be necessary to abort the procedure
and repeat it after several months of healing.
During the 3-6 months stabilization period after surgery,
most patients experience some minor side effects. These
include:
- Increased light sensitivity
- Some glare from light sources at night (starburst
effect)
- Changes to visual acuity. Corrected vision may regress
slightly and require an enhancement.
If you have more questions concerning complications or side
effects, please attend a free consultation. [top

Are there any restrictions after
surgery?
There are no restrictions on daily activities.
However, for the first day or two following surgery, we
suggest that you plan nothing more than to rest and relax. For
the first 3 days after surgery, you must not get anything in
your eyes, including soap and water. Additionally, you are
prohibited from wearing eye makeup and going swimming for one
week following surgery. You may drive when your vision clears
and you can return to work or school in 1-3 days. [top
