History of Vision Correction Procedures
VISX® Star S4 ActiveTrak Laser
PRK - Photorefractive
- PRK vs. LASIK
In the early 1980's, the concept of laser treatment for vision correction
was developed and became FDA approved in the 1990's. The Excimer laser
offers a tremendous amount of precision, control and safety for vision
LASIK, or Laser in-Sitiu Keratomileusis, is the procedure of choice used
in conjunction with the Excimer laser. The computer-assisted procedure
offers a number of benefits because it is performed under a protective
layer of corneal tissue. (The original laser procedure, PRK, is performed
on the surface of the cornea). The LASIK procedure results in less surface
area to heal, less risk of scarring, less risk of corneal haze, less postoperative
discomfort, less postoperative need for medication and vision is restored
more rapidly. LASIK can also treat a higher range of refractive errors.
The LASIK Procedure
The LASIK procedure is incredibly fast, accurate and virtually painless.
In about 60 seconds, it will change your life forever! Immediately prior
to the procedure, patients receive a mild sedative for relaxation. This
is followed with topical anesthesia eye drops to completely numb the eye.
An eyelid holder is placed between your eyelids to prevent you from blinking
during the procedure.
Next, a hinged corneal flap is made to reveal the inner corneal tissue.
During this process, you will feel a little pressure, but no discomfort.
The cool laser beam gently reshapes your cornea, usually in less than
60 seconds! The laser beam can remove 39-millionths of an inch of tissue
in 12-billionths of a second.
precision of the LASIK procedure, demonstrated on a strand of hair.
The greater the accuracy, the better the results of your final vision.
In fact, the lasers are so precise, only 3% of all patients will require
an enhancement procedure at a later date.
The procedure is concluded when the hinged corneal flap is folded back
into place where it bonds naturally within minutes after surgery, without
the need for sutures. You will be able to see immediately with your new
vision. However, it can take up to 3 months before you obtain your optimum
vision. Although the LASIK laser is incredibly accurate, there are no
guarantees that everyone can obtain 20/20 vision.
How LASIK Works
To treat nearsightedness, the cornea must be made flatter. This is accomplished
by removing tissue from the center of the cornea. To treat farsightedness,
the cornea is made steeper. This is accomplished by directing the laser
beam to remove tissue around the center of the cornea. To treat astigmatism,
the cornea must be made more spherical. By changing the pattern of the
beam, tissue is removed in one direction more than the other.

New VISX® Star S4 ActiveTrak Laser
Once again the Beitman Laser Eye Institute leads the way in LASIK laser
technology in Michigan by offering the new VISX® Star S4 ActiveTrak
laser, with 3-D infrared eye tracking system for vision correction. This
breakthrough technology results in the most accurate and comfortable laser
vision correction procedure available anywhere worldwide!
The state-of-the-art eye tracking
technology maximizes the treatment and results of vision correction surgery
by precisely following the patient's eye movements to deliver each laser
pulse as prescribed.
As laser treatment is applied during LASIK, dual infrared cameras compensate
for a patient's eye movement. The cameras track 3-dimensional movement
of the cornea during the LASIK treatment which includes side-to-side and
up-and-down movement. If the patient's eye moves outside the treatment
zone, the laser automatically shuts down in a fraction of a second. When
the eye returns to the treatment zone, Dr. Beitman can continue with the
procedure. As a result, the patient has a decreased risk of decentered
laser pulses, and thus receives a more effective surgery outcome.
Compared to other lasers, studies have shown the larger, 6.5 mm
optical zone of the VISX® laser can produce improved night vision for
patients with a higher risk for nighttime glare. The 7-beam scanning array
technology with the new laser creates a smooth corneal surface that leads
to better visual acuity and quicker recovery!
The VISX® Star S3 Excimer laser and its patented active eye tracking
technology was approved by the FDA in 2000. The official treatment parameters
for the new laser are:
Up to 5 diopters of farsightedness with up to 4 diopters of astigmatism
Up to 14 diopters of nearsightedness with up to 5 diopters of astigmatism.

As with LASIK, there are no incisions made in the eye. After the eye's
protective epithelium (layer of cells that regenerate weekly) is removed,
the change to the cornea is made at the Bowman's layer. Computer-driven
pulses of the laser beam are directed on the surface of the cornea, reshaping
it to reduce or eliminate refractive disorders.
The cornea maintains its original integrity since a very thin disk is
removed. This is also true with LASIK. Because the PRK procedure makes
changes on the surface of the eye, a "scuffing or raspberry"
sensation is created over the central vision of the eye and will last
several days to two weeks. This impacts the initial clarity of the vision
and the healing process is considerably longer than LASIK. A steroid regimen
is required to enhance the healing process.
The pre- and post-procedure care
will be provided by either Beitman Laser Eye Institute or one of it's
many affiliate co-managing doctors of optometry. During this process,
your doctor will:
you about the laser and alternative treatments
realistic expectations, risks and limitations
a thorough eye exam and testing
post-operative care as necessary
