Purpose:
To identify current indications and trends in indications for penetrating keratoplasty (PKP) and associated procedures.
Methods:
Retrospective chart review of all patients who underwent PKP at Wills Eye Institute from January 1, 2001, to December 31, 2005.
Results:
A total of 1,162 cases were performed in this 5-year period. Leading indications for PKP were pseudophakic corneal edema (PCE) in 330 (28.4%) cases, followed by regraft in 250 (22.0%), keratoconus in 186 (16%), and Fuchs' endothelial dystrophy in 126 (10.8%) cases. Of the 330 cases of PCE, 232 (70.3%) were associated with posterior chamber intraocular lenses (PCIOLs) and 96 (29.1%) with anterior chamber lenses. In 330 eyes with PCE, the lens was not exchanged in 246 (74.5%) cases and was exchanged in 76 (23%) cases. Seventy of the exchanged lenses were anterior chamber intraocular lenses (ACIOLs) and six lenses were PCIOLs. In cases of ACIOL exchanges, 10 were for scleral sutured IOLs, 18 for PCIOLS, and 42 for another ACIOL.
Conclusions:
Pseudophakic corneal edema remains the leading indication for PKP at our institution followed by regraft, continuing a trend noted in our previous studies. Although the percentage of cases of PCE associated with PCIOLS increased, fewer lenses were exchanged, perhaps reflecting increased confidence in biocompatibility of newer IOLs. The decrease in overall number of corneal transplants in these 5 years continues a trend noted in our previous study and mirrors the national decline in PKP.
