Do
You Wear Contacts or Glasses?
Put Them Away.
Many people depend on wearing glasses or contacts everyday.
Glasses and contacts can be a hassle though, especially for
active people on the go. With Lasik vision correction
surgery, losing contact lenses or forgetting where you put
your eyeglasses
can be a thing of the past. For most people who have Lasik
surgery, vision is greatly improved reducing or completely
eliminating the need for corrective lenses.
There is always new technology with Lasik procedures. There
are several types of Lasik procedures that can successfully
be used on a patient. The type of procedure that you will have
will depend on what your Lasik doctor prefers and what works
best for your eyes. WAVEFRONT Lasik is the most commonly
used Lasik procedure. There are also procedures called diagnostic
workstation and Orbscan technology.
In general, Lasik is performed to restore vision and the
results are immediate. A surgical instrument called a microkreatome
is used during the procedure to create a thin, circular flap
in the cornea. This flap can also be created using a laser,
which is usually more precise and has a higher success rate.
After the flap on the cornea has been cut, the doctor folds
the flap out of the way and removes some of the corneal tissue.
This is done using what is called an eximer laser. This laser
uses cool ultraviolet light beams to remove very small pieces
of the tissue. After the tissue is removed, the cornea is reshaped
causing it to work better focusing light into the eye and onto
the retina. This results in the patient immediately having
better, clearer vision that before the procedure. The flap
is put back in place to cover the area where the tissue was
removed.
The
Lasik surgery is both a quick and relatively painless procedure
for most patients. During the surgery, patients remain
awake and are able to walk out after the procedure. The procedure
is also painless because the surgeon will give the patient
eye drops that anesthetize the eye before the surgery begins.
Some patients who are uncomfortable about the procedure can
be given a mild sedative before the procedure begins. Before
the procedure begins, the patient will lie down and the doctor
will place a special device to keep the eyelids open during
the surgery. Also, this device has a suction ring on it to
keep the eye pressurized. Once the surgery begins, it only
takes about one minute for the whole procedure to take place.
If
your doctor uses a laser during your procedure, the computer
is adjusted so that the laser can remove the right amount of
corneal tissue. While the procedure is painless and quick,
you might hear the clicking sound of the laser and be able
to smell a slightly acidic order. This is caused by the tissue
removal. The surgeon has complete control of the laser and
it can be stopped at any time during the procedure. If you
choose to have both eyes done, the doctor might choose to wait
for a little while before operating on the next eye. Some patients
prefer to have the second eye done a week or more after the
initial procedure.
WAVEFRONT
is generally considered the most trusted procedure and
is though to produce the best results. This procedure is
popular because as a general rule, WAVEFRONT can be customized
to treat your eyes. This gives much better results to the patient.
Also, with this technique, some patients have better vision,
sometimes 20/15 after having WAVEFRONT Lasik. In a study comparing
WAVEFRONT to the conventional Lasik procedure, 90 to 94 percent
of all patients had 20/20 vision or better after the procedure.
This is compared to 80 percent of patients that achieve 20/20
vision with the conventional method. Also, many doctors prefer
the WAVEFRONT procedure. This is because this procedure decreases
the risk of complications such as haloes or night glare
The diagnostic workstation technology has advantages because
it can cover a much larger area since the pupil can dilate
up to twice the normal size. The Orbscan technology also has
its advantages. It can determine without a doubt if you are
a good candidate for this procedure. The Orbscan has the ability
to be more accurate diagnosis and treatment of vision problems.
