The Wonders of Lasre Eye Surgery: How It Works
By Nathalie Fiset
Lasre Eye surgery has been one of technology's
greatest products that has positively improved the way things
work. It has a number
of applications and benefits, including in the field of medicine.
An excellent example is Lasre Eye surgery.
Lasre eye surgery has given 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 lasre 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.
lasre 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 lasre
beams to change the shape of the cornea to one that is most effective for vision.
So how does Lasre 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 lasre beam that is directed to the cornea, reflected and produces a 3D image on the aberrometer's screen.
The most common form of lasre Eye surgery is LASIK or lasre assisted in-situ keratomileusis. This lasre 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 lasre 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 lasre
In-Situ Keratomileusis. This Lasre 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 lasre
beam. Afterwards, the epithelium is restored to its normal position.
As was mentioned above, this Lasre 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.
lasre 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 lasre Eye surgery. This is to prevent more serious and permanent
damage to the eyes that can lead to blindness.
Lasre 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. It enters the
circulation and into the area beneath the retina where new blood
vessels are formed. A non-thermal red lasre is then used to activate
Visudyne molecules. The activated molecules begin sealing holes
and destroying unhealthy blood vessels.
Lasre Eye surgery can work miracles and provide
new hope for people with vision problems of varying degrees.
The key is to
diagnose the condition and carefully evaluate which lasre Eye
surgery technique will work best for the patient and you physician
will do this for you.
