Even with complex procedures like corneal transplants,
surgery is an option at our ambulatory surgery center. In a corneal
transplant surgery the damaged cornea is replaced with a clear donor
cornea.
The cornea is the front window of the eye. When it is
damaged
through trauma or disease, we are one of the
few practices in
Indiana that can help. We specialize in
corneal transplants that
replace the injured or diseased
cornea with a healthy clear
harvested cornea.

For Gertrude good vision is imperative for her sewing projects. When she
discovered she needed a corneal transplant she knew she was in good
hands at Grossnickle Eye Center. In the months since Gertrude’s surgery
her vision has improved dramatically.

DSEK
(Descemet Stripping Endothelial Keratoplasty)
DSEK is a variation or method of corneal
transplantation. DSEK involves only replacing some
of the posterior or inner layers of the cornea as
compared to the standard corneal transplantation
when the full thickness of the cornea is replaced or
in the anterior lamellar corneal transplants where
only the anterior layers of the cornea are replaced.
While both the standard corneal transplants and the
anterior lamellar corneal transplants have been done
for many years, surgery that only replaces the
posterior layers of the cornea is relatively new. DSEK surgery is more complex than either traditional
corneal transplants or anterior corneal transplants.
Some of the advantages of the surgery as compared to
standard corneal transplantation are: a smaller
wound and fewer stitches are needed and in some
cases, no stitches are used at all; the eye heals
faster and vision can return in 3-6 months compared
to up to one (1) year; the eye is less susceptible
to injury and rupture; one's glasses should be
similar to what they were prior to surgery with
smaller changes in astigmatism, nearsightedness or
farsightedness; and incidence of stitches causing
infection or irritation should be greatly reduced.
Some of the disadvantages of the surgery are: the
surgery is relatively new and has only been done for
a few years, it is not known if this method will
affect how long the surgery may be good or how long
the effect will last; if unusual scarring occurs
between the layers of the donated cornea and your
own cornea, the vision might be decreased and you
could still need a standard form of corneal
transplantation to improve your vision; and
difficulties could occur during surgery where the
surgery would have to be converted to a standard
corneal transplant. Disadvantages that can also
occur with standard corneal transplantation are:
damage to the iris or colored part of the eye which
could change the shape of the pupil or appearance of
the iris; and during surgery, damage could occur to
the natural lens to either speed up or cause the
development of a cataract. |
