Purpose:
To determine the leading indication for penetrating keratoplasty.
Material and Method
:The authors retrospectively performed a chart review of the hospital
records of all patients who underwent penetrating keratoplasty at Maharaj Nakorn Chiang Mai Hospital
between January 1996 and December 1999.
Results
: A total of 45 corneal transplants were performed. The leading indications for
penetrating keratoplasty, in order of decreasing frequency, were bullous keratopathy (28.9%), corneal
scar (22.2% ), corneal dystrophy and degeneration (20.0% ), corneal ulcer ( 17.8% ), regraft (8.9% ). and
trauma (2.2% ).
Conclusion
: Bullous keratopathy was the leading indication for penetrating keratoplasty at
Maharaj Nakorn Chiang Mai Hospital from 1996 to 1999, followed by corneal scar. The major cause of
bullous keratopathy was associated with posterior chamber intraocular lens implantation.
Key word
: Penetrating Keratoplasty, Bullous Keratopathy
