Limbal
Relaxing Incisions or Arcuate Incisions
Incisions
in the cornea are accomplished with a special diamond scalpel where
the blade
depth is set by a micrometer as determined by the corneal thickness.
These incisions
are placed in the steep or more curved portion of the cornea in order
to reduce the
curvature and in that way reduce the astigmatism. Limbal
relaxing incisions are placed just inside the white portion of the
eye (sclera). Arcuate incisions are placed in the
more central clear portion of the cornea.

Astigmatism
If
you have astigmatism,
objects will be blurry and could be doubled both far and/or near depending
on whether you have nearsighted or farsighted astigmatism.
Astigmatism
is a condition which occurs when the cornea has more than one curvature
(like a football as opposed to a basketball). These multiple curvatures
bend light differently and blurred vision is the result. Normal and
purely nearsighted
(Myopic) or purely
farsighted (Hyperopic) eyes have one focal point. There is no such
thing a pure astigmatism (where there is no nearsightedness or farsightedness).
With astigmatism,
your eyes have two different focal points. For nearsighted eyes with
astigmatism,
both focal points are in either in front of o the retina or one is focused
on the retina and one in front of the retina. For farsighted eyes with
astigmatis, both focal points are focused behind the retina or one is
on the retina and one behind the retina. Although the word astigmatism
to a layman sounds somewhat more serious (stigmata) than nearsightedness
(Myopia) or farsightedness
(Hyperopia), in reality most eyes have some degree of astigmatism.
Laser vision surgery is quite accurate at correcting astigmatism of
up to 4 or 5 Diopters in combination with the correction of myopia or
hyperopia.
