Laser
Surgery
Laser "surgery"
takes only a few minutes
to perform, and the
results can be amazing.
In addition to
refractive surgery for
corrective vision,
removal of an
"after-cataract",
glaucoma and diabetes
are just a few of the
other conditions that
can be treated with
lasers.
Refractive
Surgery
|
|
When
the lens of the
eye is removed,
it is referred
to as
lensectomy. If
the lens is
cloudy, the
lens is called
a cataract.
Removal of a
cloudy lens is
called cataract
surgery. If the
lens is clear
and removed for
refractive
correction, it
is called clear
lens extraction
or refractive
lensectomy.
|
Refractive lensectomy is
the same procedure as
modern "no-stitch",
"no-needle" cataract
surgery. It changes the
eyes optics by replacing
the natural lens with a
lens implant that is
specifically chosen
based upon measurements
taken during your
preoperative assessment.
The lens implant remains
in place for your
lifetime. In the past,
the lens was usually
selected to focus
clearly for distant
objects; thus glasses
are needed for near
vision activities like
reading. Now, multifocal
options, that provide
distance for distance
and reading, exist.
Astigmatism can also be
corrected during this
procedure using a
techniqued called limbal
relaxing incisions. This
is a reshaping of the
cornea, performed during
the lensectomy, to
minimize astigmatism and
reduce dependence on
glasses.
Lensectomy may be an
attractive option for
people over 45 years of
age. For those
individuals above 45,
the natural ability to
focus up-close is
progressively lost.
Individuals over 55
usually do not have much
natural focusing ability
for near vision. Thus,
refractive lensectomy
may be a wise choice for
individuals above
55.
Refractive lensectomy is
a simple outpatient
procedure. In most
cases, only eye drops
are needed to numb the
eye for the surgery.
People are not "put to
sleep"; but are given
oral or intravenous
medication for comfort.
A small incision is made
in the cornea
(approximately 3 mm).
Using a special
ultrasound probe, the
lens is gently removed
in small particles.
After the natural lens
is removed, a lens
implant of appropriate
power is placed through
the incision and into
the proper location.
The surgery is usually
completed without
stitches and takes about
15 minutes.
Tired of wearing glasses
or contacts? Laser
refractive surgeries are
brief outpatient
procedures that reduce
your dependency on
glasses or contact
lenses. If you are
nearsighted, farsighted
or have astigmatism you
may be a candidate.
Our surgeons are skilled
in all these procedures
and can easily identify
the best procedure for
you.

INTRALASE
|
The
INTRALASE FS
Laser uses
infrared light
to precisely
cut tissue by a
process called
photodisruption.
The
laser’s
IntraLASIK
software
directs the
process,
focusing the
beam via optics
into a tiny 2
to 3 micron
spot of energy.
The beam passes
harmlessly
through the
outer layers of
the cornea
until it
reaches its
exact focal
point within
the stroma
(central layer
of the cornea).
When it reaches
this focal
point, the beam
forms a
microscopic
cavitation
bubble of
carbon dioxide
and water
vapor.
Thousands of
these bubbles
are placed at a
precisely
controlled
depth to create
a dissection
plane, and then
the laser beam
stacks a
pattern of
bubbles along
the periphery
of the
plane

up
to the corneal
surface. An
uncut section
of tissue is
pre-programmed
to act as a
hinge for the
newly created
corneal flap.
By utilizing
this rapidly
fired
femtosecond
laser, and
interconnecting
the bubbles
very tightly,
the surgeon may
program the
laser to
customize a
corneal flap
with remarkable
precision and a
distinctive
beveled edge.
The beveled
edge of the
corneal flap
allows for a
precise
realignment and
seating of the
flap after
interior
corneal
reshaping is
completed.
|
Because the low energy
pulse from the INTRALASE
FS Laser is in the
femtosecond range - a
mere quadrillionth of a
second - there is no
heat damage to
surrounding tissue. With
no transmission of shock
wave to surrounding
tissue, the femtosecond
laser is well suited for
delicate corneal
surgery.
The computer-controlled
INTRALASE FS Laser and
it’s IntraLASIK
software bring a level
of accuracy, precision,
and control to flap
creation that was
previously impossible.
With the INTRALASE FS
Laser, flaps can be made
that are very accurate
and highly consistent in
both thickness and
diameter. The IntraLASIK
software allows the
surgeon to custom design
precise corneal
resection for individual
patients.
LASIK
|
LASIK
(laser in-situ
keratomileusis)
is a procedure
that involves
creating a
hinged "flap"
of corneal
tissue with the
use of a very
precise
instrument
called a
microkeratome.
The laser
reshapes the
cornea beneath
the flap, and
the flap is
then
repositioned
over the
treated area.
This procedure
has become the
most popular
refractive
procedure
because of the
rapid visual
recovery
time.

PRK
PRK (Photorefractive
Keratotomy) PRK utilizes
the highly precise
technology of the
excimer laser and the
latest computer
technology to reshape,
or resculpt, the front
portion of the cornea,
to improve vision. By
using the excimer laser,
the ultraviolet light
can be focused in short,
high energy bursts to
remove microscopic
layers of central
corneal tissue to cause
the retina to flatten.
Prior to the procedure,
a number of measurements
of the eye will be taken
and entered into the
computer-controlled
excimer laser to produce
a high degree of
accuracy and precision
for each individual
patient's desired
correction. Typically,
the procedure is
accomplished in about 2
minutes under a topical
anesthetic. Due to the
unique properties of the
"cold" excimer laser,
the possibility of
thermal damage to
surrounding tissue is
entirely eliminated.
RK
RK (Radial Keratotomy)
RK refers to a series of
radial, or spoke-like
incisions, that are
strategically placed
around the central
portion of the cornea to
cause it to flatten,
which improves vision in
myopic patients. The
incisions are made only
in the outer, or
peripheral, portion and
not at the center
(optical zone), the area
through which we see.
The length, number and
pattern of the
microscopic incisions
depend on the patient's
age and degree of
nearsightedness. As the
incisions heal, the
cornea flattens thereby
changing the way in
which light is focused
on the retina. RK is
performed in our
specially equipped
in-office laser and
surgicenter under
topical anesthetic.
AK
AK (Astigmatic
Keratotomy ) is similar
to RK and is used to
correct astigmatism. An
astigmatic eye generally
has a cornea shaped like
a football or teaspoon,
and relaxing incisions
are performed in an
attempt to make the
cornea more round. AK is
often combined with RK
and has a similar long
track record.
