HOW LONG WILL MY LASIK PROCEDURE TAKE?
The LASIK procedure time is between five and fifteen minutes. We ask
our patients to plan to be with us for approximately two hours on the
day of their treatment. This gives our medical team adequate time for
your procedure preparation, additional paperwork, final examination,
and give you an opportunity to ask questions after your vision
correction.
LASIK
LASIK is a more complex procedure than PRK. It is performed for all
degrees of nearsightedness. The surgeon uses a knife called a
microkeratome to cut a flap of corneal tissue, removes the targeted
tissue beneath it with the laser, and then replaces the flap.
"With LASIK, the skill of the surgeon is important because he'll be
making an incision," says Stephen Crawford, O.D., an optometrist
practicing in Virginia, "compared to the PRK method where the machine
does more of the work." Crawford urges people to find qualified,
experienced doctors to perform this surgery. "You'll want someone who's
done a number of LASIK procedures since this is a surgeon-dependent
operation," he said.
According to Ken Taylor, O.D., vice president of Arthur D. Little,
Inc., a technology and management consultant firm in Cambridge, Mass.,
"Last year, across the country, 40 to 45 percent of refractive
surgeries performed by physicians were LASIK, which equates to
approximately 80,000 procedures." Doctors not participating in clinical
trials may choose to use the approved laser to perform LASIK procedures
at their discretion, says Morris Waxler, Ph.D., chief of FDA's
diagnostic and surgical devices section. But most uses are considered
"off label" and are not regulated by FDA.

Wavefront / Custom LASIK
At Laser Eye Center, our surgeons are the first to utilize LADARWavey®
CUSTOMCORNEA® wavefront technology to measure and address both lower
and higher order aberrations (visual imperfections in the eye's optical
system). Unless both lower and higher order aberrations are addressed
during laser vision correction, the quality of your vision may not be
ideal, even if you have post-operative vision of 20/20.
Nearsightedness- Nearsightedness is another name for Myopia.
Nearsighted people typically have difficulty seeing objects at a
distance. Nearsightedness can be so severe that people have difficulty
seeing objects up close too.

LASIK stands for Laser-Assisted In Situ Keratomileusis and is a
procedure that permanently changes the shape of the cornea, the clear
covering of the front of the eye, using an excimer laser. A mechanical
microkeratome (a blade device) or a laser keratome (a laser device) is
used to cut a flap in the cornea. A hinge is left at one end of this
flap. The flap is folded back revealing the stroma, the middlesection
of the cornea. Pulses from a computer-controlled laser vaporize a
portion of the stroma and the flap is replaced. There are other
techniques and many new terms related to LASIK that you may hear about.
Nearsighted, Myopia:
People can typically see things up close, but things far away may
appear blurred. People who are nearsighted may find a negative number
in the sphere column of their prescription. Dr. Boothe
LASIK- LASIK is an acronym that allows us to quickly say, "laser
assisted in situ keratomileusis." This is more simply said as
"reshaping the cornea using a laser."
IOL or Intraocular Lens Implant- A lens is implanted in front of, or in
place of, the eye's natural lens. IOLs may be a great option for
patients with severe vision prescriptions.

Hyperopia or Hypermetropia- Many Hyperopic patients have difficulty
seeing things up close, and often have crisp-acute distance vision.

Keratectomy- Keratos is the greek word for cornea, and ectomy means to remove. Together they mean to remove corneal tissue.
LADAR
Using laser and radar technology developed by NASA, LADARVision® was
the first approved system with active eye tracking, which compensates
for involuntary eye movements. Although other laser systems have now
developed eye-tracking systems, LADARVision® has the only system
utilizing laser radar tracking technology, a system that measures eye
movement 4,000 times each second and is capable of following eye
movements regardless of how rapid or erratic they may be. Successful
laser application does not rely on your ability to hold your eye
perfectly still. Dr. Boothe
Refractive Error- This word refers to vision problems associated with the cornea: Astigmatism, Hyperopia, and Myopia.
Optician- An optician makes glasses and performs adjustments on frames. Dr. Boothe Lasik
What the FDA regulates
In the United States, the Food and Drug Administration (FDA) regulates
the sale of medical devices such as the lasers used for LASIK. Before a
medical device can be legally sold in the U.S., the person or company
that wants to sell the device must seek approval from the FDA. To gain
approval, they must present evidence that the device is reasonably safe
and effective for a particular use, the "indication." Once the FDA has
approved a medical device, a doctor may decide to use that device for
other indications if the doctor feels it is in the best interest of a
patient. The use of an approved device for other than its FDA-approved
indication is called "off-label use." The FDA does not regulate
off-label use or the practice of medicine.
Monovision- When one eye is deliberately corrected for distance vision and the other for close vision.
