Risks And Complications Of Laser Eye Surgery
Gerri Stone
Most patients who undergo refractive surgery are delighted with
the results. However, just like any other surgical procedure,
there are also some risks that come with it. This is why it is
very important to be aware of the possible complications,
effects and laser eye surgery risks.
Here is a list of the most common laser eye surgery risks, and
complications.
In order to understand the complications, there has to be a
simple understanding of the procedure of Lasik eye surgery.
Lasik eye surgery involves the cutting of a small flap in the
front covering of the eye or cornea. The flap is lifted so that
the laser may reshape the eye and then the flap is replaced as a
type of bandage.
The flap is cut using a type of bladed instrument called a
“microkeratome” or else with a laser. The surgeon’s preference
determines what technology is used. Using a laser to perform
this portion of the procedure allows for more precision and,
therefore, fewer complications are likely to arise.
Now, if the flap is not cut correctly it may fail to form
properly to the surface of the eye. The flap might also be cut
too small or thin, which would cause wrinkling upon the attempt
to adhere the flap to the surface of the eye. These
complications can lead to an irregularly shaped eye surface and
in time may lead to astigmatism or blurry vision.
Vision Loss
After the procedure, a very small percentage of all patients
experience a vision loss which cannot be corrected with
glasses, contacts or a second surgery. This is a very rare, but
very serious laser eye surgery risk.
Debilitating Visual Symptoms
Some patients experience halos, glare or double vision after
surgery. This causes serious night vision problems. Even if
they have a good vision on the vision chart, they may not see
well at night, in fog or in other situations of low contrast.
They may even see worse in these situations than they did
before treatment.
Under Treatment or Over Treatment
This is a very frequent laser eye surgery risk. Only a small
percentage of patients obtain 20/20 vision after surgery
without glasses or contacts. You may need additional treatment
to enhance vision, but this is not always possible. Even if you
used to wear very weak prescription glasses before treatment,
you may still need glasses or contact lenses afterwards. If you
used to wear reading glasses before, you might still need them
after surgery.
Severe Dry Eye Syndrome
Another laser eye surgery risk is to develop serious dry eye
syndrome. After surgery, your eyes might not be able to produce
enough tears for keeping moist. This not only produces
discomfort, by can also reduce quality vision due to permanent
blurring and other problems. This eye condition may be
permanent. It is usually treated with intensive eye drop
therapy, but other procedures can also be used.
Results Diminishing with Age
Another laser eye surgery risk is for results to decrease over
time, especially in patients with farsighted vision. If your
manifest refraction (an exam with lenses before using dilating
drops) differs from your cyclopegic refraction (another exam
with lenses after applying dilating drops), the chances of
getting this side effect are higher.
For newer technologies, there is not enough research data
available. As some of them have been developed only a few years
ago, long-term effectiveness and safety cannot be determined
yet. Even though they are more advanced, they might have some
unknown long-term side effects.
As with any surgical procedure, there are a variety of
complications. Care must be taken to select the right Lasik eye
surgeon for your specific needs and also to decide of Lasik eye
surgery is the right procedure for you. The most important
factor in successful surgery is to find an experienced surgeon,
who will monitor your follow up care, and be there with you if
you find yourself having any of these complications.
