A cataract laser surgery might be necessary when the condition has
progressed too much. A cataract is a disease where the eye lenses start
to cloud. Normally these lenses are able to focus the light that enters
the eyes into the retina, which can produce a clear image.
The lenses are mostly composed of proteins and water. As the body
starts aging these lenses also age causing the proteins to clump
together. When time passes the area covered by these proteins grows
bigger and the vision decreases until the point where the sight is
The causes for
this disease are not completely understood. However, there are
certain factors that can increase the chance of suffering from it.
Exposition to ultraviolet light for a long time as well radiation can
definitely cause damage to the eye lenses which can result in
cataracts. Areas where the ozone
layer is known to be thinner will have
more ultraviolet rays which can lead to more people with the condition.
Diseases like diabetes
can also accelerate the damage
to the lenses which can result in suffering cataracts. This illness
typically does not present any symptoms until the damage to your vision
is too great.
often recommended to treat the problem
The first surgery
involves extracting the cataract. This is done by making a small cut
into the cornea. Then the central portion of the capsule is removed by
using sound waves. This procedure is normally enough to solve the
condition but there are times when the problem might come back then a
second surgery is needed.
One of the most effective treatments for the disorder is the cataract
laser surgery. This type of surgery is frequently used to treat a
that has formed after a first surgery has been done.
Only around 30% of the people that has cataract surgery need a second
This type of laser surgical procedure uses a laser to create a
aperture in the capsule where the cataract can be found. The aperture
is enough to allow the light to pass through resulting in a clear
vision. The laser is focused only at one point and the surrounding
tissue is not affected. Complications after the procedure are still
possible. One of them is the temporary increase in the internal
pressure of the eye which can harm the intraocular lens. In some rare
cases the anterior vitreal face can rupture leading to cystoid macular
Another type of laser surgery consists in making
cut in the upper layer of the cornea then reshaping the layer
underneath. This improves the vision and prevents complications. The
cataract laser surgery is normally used when all other alternatives
have been used.
Consult with your doctor if the surgical procedure is
right for you.
