Homologous sclera and autologous fascia lata have been accepted as common wrapping materials for hydroxyapatite implantation; however, various problems have been observed, such as the risk of transmittable diseases such as AIDS or hepatitis. This report details the use of cadaver dura mater to wrap hydroxyapatite implants. For 73 eyes of 73 patients with hydroxyapatite implantation, cadaver dura mater was used to wrap the hydroxyapatite after enucleation or secondary implantation. Of the 73 patients, 20 had conjunctival erosion; however, all of the patients but 1 healed spontaneously within an average of 22 days. Only 1 of the 73 patients progressed to implant exposure requiring a dermis graft. The authors suggest that cadaver dura mater is a suitable wrapping material for hydroxyapatite implantation.
