Work
 Laser
technology has been one of technology's
greatest products that have positively
improved the way things work. It has a
number of applications and benefits,
including in the field of medicine. An
excellent example is laser eye
surgery.
Laser eye surgery has offered hope to
people with eye problems, be it with
vision or aesthetic aspects. For most
people thinking of undergoing it, the
first question is of course how laser eye
surgery works.
Common problems concerning poor vision
can be caused by distortions on the
surface of the eye and its components.
Light rays may be poorly reflected
resulting in poor vision. This accounts
for common vision problems such as
astigmatism, near sightedness and far
sightedness.

Some people also find wearing
eyeglasses cumbersome while some even
become self-conscious of it. Some wear
contact lenses but still wish to go for a
more permanent solution so they wouldn't
have to be so depended on it. Laser eye
surgery can be an option for this problem
by helping correct the distortions and
improve passing of light rays. Basically,
what it does is to use laser beams to
change the shape of the cornea to one that
is most effective for
vision.
So how does laser eye surgery work?
First, the doctor has to have a clear
picture of the distortion. He uses an
aberrometer. This also works by using a
low- energy laser beam that is directed to
the cornea, reflected and produces a 3D
image on the aberrometer's screen.
The most common form of laser eye
surgery is LASIK or laser assisted in-situ
keratomileusis. This laser eye surgery
works by making a small cut to excise the
top layer of the cornea during the
surgery. It is mostly recommended because
of faster recovery period. Another option
is photorefractive keratectomy or PRK. In
this procedure, a portion of the cornea is
scraped away and then laser is used to
reshape the tissue underneath it. This was
developed earlier than LASIK with LASIK
being usually recommended because of its
very minimal discomforts.

A fusion of the wonders of LASIK and
PRK is Epi-LASIK or Epithelial Laser
In-Situ Keratomileusis. This laser eye
surgery works by making a thin flap of
corneal epithelium using a microkeratome-
like instrument. The underlying corneal
layer is separated from the epithelium
without cutting. It does not use alcohol
solution to remove the epithelial layer.
After this, the underlying cornea can be
re-shaped to correct the distortion by
using laser beam. Afterwards, the
epithelium is restored to its normal
position. As was mentioned above, this
laser eye surgery technique combines the
benefits of the other techniques with less
complications. After the procedure, the
patient will be required to wear a thin,
soft contact lens that will act like a
bandage until the area heals completely.
Healing and recovery is also faster and
may only take around 3 to 4 days.

 Laser
eye surgery also works for more
serious eye and vision problems
such as diabetic retinopathy.
Edema, swelling and leaking of
capillaries in the eye that may
accompany this complication of
diabetes can make a person a
potential candidate for laser eye
surgery. This is to prevent more
serious and permanent damage to
the eyes that can lead to
blindness.
Proliferative Diabetic
Retinopathy (PDR) is the more
serious and later stage of this
disease where laser eye surgery
is a more important choice of
treatment. The technique for this
is known as laser
photocoagulation of the
peripheral retina. The entire
procedure may be completed in as
short as 30-45 minutes per
session. It may take around 3-4
sessions to fully benefit from
this procedure with it being
performed at the doctor's
office.

Laser
eye surgery also works for age-related
vision problems. One such technique is
Photodynamic Therapy. This makes use of a
light activated dye called Visudyne. This
is introduced to the patient's arm via
injection.
