Vision Correction
Frequently Asked Questions
Who can benefit from Laser Vision Correction (LVC)?
Persons with myopia (nearsightedness), hyperopia (farsightedness)
and astigmatism may achieve vision correction through LVC procedures.
Almost any amount of myopia can be corrected, and moderate amounts
of hyperopia and astigmatism.
Am I a candidate for LVC?
Possibly. A thorough evaluation by an optometrist or ophthalmologist
is necessary to determine your suitability. Careful assessment of
your overall eye health must be performed before any decision can
be made regarding your treatment.
What does the laser do?
FDA approved Excimer laser is used to re-shape the cornea to achieve
vision correction. The curvature of the central cornea is made flatter
to correct nearsightedness. To correct farsightedness, the curvature
is increased, or made steeper. For astigmatism, the curvature is
made more uniform in all directions. The re-shaping is accomplished
by focusing the energy of the laser to remove very small amounts
of tissue from the cornea.
What is LASIK?
Laser Assisted In-Situ Keratomileusis (LASIK) is the procedure
representing the latest technology to correct refractive errors.
LASIK combines the precision of the Excimer laser with a quicker
return to normal activities. In light of the accuracy and quicker
recovery, LASIK has become the preferred procedure in most cases.
In performing LASIK, the surgeon creates a hinged flap by folding
back a thin layer of the superficial cornea. The corneal tissue
beneath the flap is then reshaped using the high energy pulses of
the Excimer laser. The flap is then folded back in place and heals
without the need for sutures.
Does it hurt?
To the surprise (and relief) of most patients, minimal discomfort
occurs. Patients are awake and alert during the procedure. Typically,
anesthetic eye drops are all that is required to avoid discomfort.
The entire procedure usually takes just 10 to 15 minutes.
When can I go back to work?
Most often, patients can return to work the following day.
Will I ever need eyeglasses again?
No one can guarantee that you will never need to wear eyeglasses
again. Most patients are able to function well for distance vision
tasks without correction following LASIK. Patients can expect to
reduce their dependence on eyeglasses or contact lenses, if not
eliminate them entirely. Patients affected by presbyopia-the age
related decrease in your ability to focus at near distances-may
still require eyeglasses for reading. Your eye care professional
will assist in realizing your expectations.

FLYING SPOT
Some of the newer lasers for LASIK these days feature a narrow
beam that moves around the cornea in a manner designed to produce
a smooth and precise tissue ablation. Many doctors who have used
these so-called "flying-spot" lasers are pleased with
the results they are getting.
A flying-spot (or scanning-spot) excimer laser uses a 0.8mm to
2.0mm beam vs. the broader 6mm beams of other lasers and have won
FDA approval for this type of laser. A smaller spot enables the
doctor to place the spots exactly where needed to tailor the treatment
and be more refined.
LADAR tracking technology is a way for the laser to track small
eye movements. These are called saccadic (pron: SEKADIC) eye movements.
The eye tracker uses a small laser beam to maintain alignment to
ensure exact placement of the treatment.
Is this new laser better than the current laser (VISX)?
This new laser may not be the right laser for everyone, but it
provides a new option for many patients. The standard lasers can
treat over 85 -90% of cases. This new laser allows an expansion
of the range of patients, allowing another 5 - 10% of patients,
to be treated.
What conditions can be treated with the new laser that can't be
with the VISX Laser?
This new laser will allow surgeons an option of treating some patients
with larger pupils.
Should I be treated with the Autonomous laser Vs the VISX laser?
This is an excellent question. The doctor will decide on what would
be the best option for you at the time of your consultation. As
the surgeon evaluates the cases, the surgeon will have the option
to select what laser will better suited to treat each patient's
particular prescription.
How does this laser compare with the VISX laser?
This laser utilizes a small beam or "spot" beam to treat
the cornea while the Visx uses a "broad" beam. This allows
for treatment with increased accuracy of certain prescriptions.
Does the FDA approve this new laser?
Yes! This laser is approved to treat myopia up to -10.00 and astigmatism
up to -4.00. In addition this laser was approved on September 22,
2000 to treat hyperopia or farsightedness, with and without astigmatism.
(Hyperopia up to +6.00 diopters, and Hyperopia up to +6.00diopters
with 6.00 diopters of astigmatism. Lastly it was also approved for
mixed astigmatism.)
If I had treatment on the VISX Laser can I have an enhancement
with the new laser?
Probably, but this needs to be determined by your doctor. There
may be some circumstances that may not allow you to have an enhancement
with the new laser for example, the nature of the prescription
or the thickness of your cornea.
Is the LADAR system only available at specific sites?
Yes. Not all network surgi-centers have the Ladar technology.
