Arizona Laser Vision Correction
LASIK was first performed in the early 1990's in Greece. However,
the two main components of LASIK were performed separately many
years prior. Doctors in South America began performing corneal flap
surgery in the 1960's to correct myopia. Excimer laser correction on
the corneal surface was first performed in 1987, and since then over
2 million procedures have been performed worldwide. LASIK combines
the benefits of corneal flap surgery with the accuracy of the
excimer laser.
LASIK combines the proven techniques of both corneal flap and
excimer laser surgery, resulting in dramatic results and rapid
visual recovery. LASIK is effective for correcting most cases of
nearsightedness, farsightedness, and astigmatism. Every Nationwide
Vision patient undergoes a comprehensive series of eye tests and
examinations and has a consultation with Dr. Lefkowitz. During the
consultation the patient and surgeon discuss and plan the procedure
that best suits the individual patient. On the day of the surgery,
the patient is brought to the laser suite and positioned upon a
comfortable chair that reclines. Topical anesthetic drops are
provided to "numb" the eye. The LASIK flap is created with a precise
instrument called a microkeratome (pictured at left). The
microkeratome makes a corneal flap that is approximately 1/4 to 1/3
of the corneal thickness. The surgeon lifts the corneal flap and
folds it over (still securely attached to the eye by its hinge).
Next, the surgeon uses the excimer laser to reshape microscopic
amounts of corneal stromal tissue to provide precise correction of
the patient's refractive error. When the laser portion of the
procedure is complete (usually less than one minute) the corneal
flap is returned to its original position where it seals back into
its proper position within minutes, and continues to heal with
increasing strength over the next few weeks.

ASA is an outpatient procedure, done under topical anesthetic eye
drops. It takes about fifteen minutes. The epithelium, the outer
cell layer of the cornea, is removed with a blade, alcohol or a
laser. An excimer laser, which produces ultraviolet light and emits
high-energy pulses, is used to remove a thin layer of corneal
tissue. The laser beam vaporizes the surface of the cornea up to
that precise depth. By breaking the bonds that hold the tissue
molecules together, your cornea is reshaped, correcting the
refractive error. Because no incisions are made, the procedure does
not weaken the structure of the come?
More recent variations of PRK include procedures which replace the
corneal epithelium after removing it with alcohol (LASEK) or an
instrument with a blade similar to the microkeratomes sometimes used
for LASIK (Epi-LASIK). Collectively, all of these procedures are
considered variations of surface ablation of the cornea, and in the
literature any of them may be referred to as "advanced surface
ablation". All of these are essentially the same procedure and yield
the same visual results
Possible complications of ASA surgery include under correction,
overcorrection, poor night vision and corneal scarring, although
permanent vision loss is very rare. In the 1990's, concern over
corneal haze formation and loss of surgical refractive effect led
surgeons to limit PRK surgeries to patients with nearsighted
corrections of 6 Diopters or less, but newer laser technology and
the use of small, one time doses of the anti-metabolite Mitomycin C
during PRK surgery have greatly expanded the range of PRK, as haze
formation is now exceedingly rare no matter what the correction.

LASIK, laser-assisted in-situ keratomileusis, is one of the most
popular vision correction procedures because it can correct
nearsightedness, farsightedness and astigmatism for a broad range of
prescriptions. LASIK corrects vision by reshaping the cornea so that
light focuses more precisely on the retina. Today, with the advanced
technology of CustomVue, combined with the expertise of the Horizon
Laser Vision Center surgeons, 99% of our nearsighted patients see
20/25 or better!
After your eye has been numbed with eye drop anesthesia, an eyelid
speculum will be positioned to hold your eyes open. You will remain
awake and comfortable throughout the procedure. Once the procedure
is completed, you will be given additional eye drops. Your vision
will probably be a little blurry at first, so have someone drive you
home and relax for the rest of the day. Recovery from LASIK is
amazingly fast.
Dr. McCulloch and Dr. Chang understand that everyone’s eyes are
unique. They are among an elite group of eye surgeons to offer their
patients the benefits of CustomVue™, the new standard in LASIK. With
this system, we can treat more than simple nearsightedness,
farsightedness and astigmatism. CustomVue™ allows us to analyze your
eyes’ specific irregularities with 25 times more accuracy than
standard measurements used for glasses or contacts to completely
customize your treatment.
With CustomVue, patients have the potential to see better than they
ever have before with glasses or contacts and with better night
vision. In fact, in a clinical study, four times as many patients
were very satisfied with their night vision after their VISX®
CustomVue™ procedure, compared to their night vision before with
glasses or contacts.
