The eye surgery which is known as ALK or in
its long form as automated lamellar keratoplasty is used to correct severe
nearsighted persons as well as those who are even mildly farsighted. While this
procedure is not as common as it once was, it is still possible to undergo the
procedure. Thanks to many updates in the medical industry with things like
lasers and other routines which have proven to offer more predictable results,
one now has many choices in which to have their vision corrected.
This surgical procedure is performed under
a local anesthetic and only takes about one hour for completion. The
ophthalmologist will then take a small device from which an incomplete flap
will be cut across the cornea. Once this flap has been created, the doctor will
then fold it over exposing the underlying tissues and make another incision
which is based on the prescription of the patient. After the incision is
completed the flap is then returned to its original position where it naturally
reattaches itself.
In general, keratoplasty eye surgeries are
fairly quick and in many cases painless. There is a shorter recovery time and
the time it takes for one to regain the full use of their vision is relatively
short. However it is important to keep in mind that in the event you are only
mildly nearsighted, the procedure will not be as accurate as some of the other
vision corrective surgeries that are available. There is also the potential of
developing astigmatism as a result of undergoing the procedure. You may also
have the possibility of developing a glare, an inability to wear contacts as
well as the potential for an infection as well as developing a corneal scar.
It is important to make sure you have a
coordinated session with the doctor prior to undergoing the procedure for more
information regarding it as well as specific before and after instructions.
During this time period the ophthalmologist will also perform a number of tests
including things like measuring your corneal refraction and thickness as well
as your pupil dilation.
Preparing for the procedure is not a difficult
process and while your doctor may have additional suggestions, in general the
preparations include things like not wearing your rigid eye glasses for three
weeks prior to the procedure and in the event that you wear contact lenses you
should not use them for the three day period before the procedure.
