The astigmatic keratotomy is a safe and
effective vision correction procedure. This procedure has been largely replaced
by the LASIK procedure in recent years but is still none the less available. By
making several incisions at the steep portions of the cornea, the doctor is
able to relax the astigmatism so that it returns to the normal round shape.
This procedure is quite often performed in company with other vision procedure
for correction.
It is considered that those who have only
mild vision impairments will benefit the most from this procedure and that
those with more severe impairments and astigmatisms may still need to wear
glasses after the procedure is accomplished. However it is important to keep in
mind that while this procedure is considered to be both effective as well as
safe, there is a slow healing time after the procedure which can last as much
as 3 months and there are also several days of discomfort. Furthermore, the
procedure is irreversible so regardless if the results are good or bad, there
is no way of returning the vision to its previous levels.
The side effects associated with astigmatic
keratotomy while rare include things like fluctuations in your vision mainly
during the first couple of months following the procedure and while the eye is
still healing. There is a chance of a weakened cornea which can even rupture if
it is directly hit. Let’s not forget the potential of an infection as well as
the virtual improbability of being able to use contact lenses should the vision
correction not be 100%. You may also have to deal with flare or starbursts
around lights especially during night-time driving which may also become a
permanent issue. Finally there is also the potential of sensitivity to light
for the remainder of your life.
Although these complications and
side-effects may seem a bit extravagant, they are nothing in comparison to the
potential of returning your vision to at least 20/40. Just imagine no longer
having to wear glasses ever again. Regardless though, you must still be willing
to accept the possible side effects along with the surgery if you choose to
undergo it.
