Effect of Keratectomy on Hydroxyapatite Exposure in Evisceration

ABSTRACT

The exposure rate of hydroxyapatite is higher in evisceration than in enucleation. This study is to compare the exposure rate of hydroxyapatite after evisceration with keratectomy and that without keratectomy. We reviewed 89medical records of the patients who had received eviscera- tion with hydroxyapatite implantation retrospectively. Of the 69 patients who had not received keratectomy during the eviceration, 9 patients (13%) had postoperative hydroxyapatite exposure. None of the 20 patients who had received keratectomy had exposure. In case of hydroxyapatite implantation after evisceration, keratectomy and 360 . circumferential sclerotomy will decrease the exposure rate of hydroxyapatite.
