| Summary: |
Beside immune reactions
high astigmatism is the mayor problem after keratoplasty.
Procedures for correction of postkeratoplasty
astigmatism are suture adjustment or renewing of the
running suture, early suture removal, early fitting of
toric contact lenses, arcuate or circular keratotomies,
LASIK surgery, implantation of toric posterior chamber
intraocular lenses or even regrafting in relapsing
keratokonus for instance. The indication for each of
these procedures will be discussed. The best way,
however, to deal with PKP astigmatism is prevention.
Therefore, guided trephine systems like the so-called
GTS or the Deutschmann trephine are recommended. Exact
suturing under keratoscopic control and the use of
intracorneal rings especially in trauma cases are
helpful, too. The aim of the correction of
postkeratoplasty astigmatism is getting a good
uncorrected visual acuity after keratoplasty. |
