PURPOSE: To compare the changes in endothelial cell density (ECD) in post-penetrating keratoplasty (PKP) patients after cataract extraction with phacoemulsification or planned extracapsular cataract extraction (ECCE). SETTING: Haydarpasa Numune Education and Research Hospital, Ophthalmology Clinic, Istanbul, Turkey. DESIGN: Clinical trial. METHODS: Eyes with hard nuclear cataract that had previous PKP were randomly assigned to have phacoemulsification or ECCE. Noncontact specular microscopy was performed preoperatively and 1, 3, and 6 months postoperatively. RESULTS: Twenty-six eyes of 26 patients were enrolled (14 phacoemulsification; 12 ECCE). Six months postoperatively, the mean corneal ECD was statistically significantly lower in the phacoemulsification group (1869.50 cells/mm(2) ± 158.05 [SD]) than in the ECCE group (1996.00 ± 127.96 cells/mm(2)) (P=.024). The mean percentage of endothelial cell loss at 6 months was 20.3% and 12.7%, respectively (P<.05). In both groups, there was no significant difference in the percentage hexagonality between preoperatively and postoperatively (P>.05). CONCLUSION: Extracapsular cataract extraction seemed to cause less endothelial cell damage than phacoemulsification in post-PKP patients with hard nuclear cataract.
