Abstract:
The hydroxyapatite implant, recetnly widely used new intraorbital implant, in light, highly biocompatible, characterized by easy fibrovascular proliferation. Thus, when inserted after evisceration, it has some beneficial effect cosmetically: it can cause less protrusion of implant or alteration of position and can have good artificial eye motion by linking to the implant. However, in case of hydroxyapatite implantation after evisceration with the cornea preserved, there is a risk of cornea melting by contact with the implant, and in case with the cornea preserved of the eyeball size being too small, hydroxyapatite implant is impossible after evisceration. Hydroxyapatite implantation is done after enucleation using donor sclera, which is not readily available in Korea. Thus we inserted hydroxyapatite implant covered with circular from of Vicryl mesh on endothelium after evisceration in 11 eyes, and inserted hydroxyapatite implant using autologous sclera with Vicryl mesh after enucleation in 3 eyes, in which 18 mm-sized implant could not be implanted after evisceration from August 195 to July 1996. Follow-up examination was done during 6 to 20 (mean 12.9) months postoperatively. Motion of extraocular muscle was very good. During follow-up examination, adverse effects such as conjunctival wound dehiscence and exposure or protrusion of hydroxyapatite implant through the conjunctiva didn`t occur. It should be considered an excellent operative method, because the hydroxyapatite implantation using autologous sclera with Vicryl mesh decreases the risk of exposure or protrusion of the implant and can be performed without the use of donor sclera.
