RESUMO

In the manufacturing of ocular prosthesis, the artificial iris is the structure responsible for its dissimulation and esthetic. The aim of this study was to evaluate interaction between paint and sealing material used in prosthetic iris painting, attempting to failures on packing of iris shell in sclera resin. It were studied four different groups, ten smooth shells sealed with cianoacrylate, ten smooth shells sealed with vinyl acetate polymer, ten rough shells sealed with ciaoacrylate and ten rough shells sealed with cianoacrylate. Specimens were analyzed with a stereoscopic magnifying glass for detection of failures, and one specimen of each group was analyzed in a scanning electron microscope for morphological analysis. None of the specimens presented failures macroscopically, which demonstrates that the protocol employed in the present study is effective; it can be concluded that failures in manufacturing of ocular prosthesis are consequence of mistakes in one of the steps of the protocol. However, it was detected microscopic defects in specimens of the groups sealed with cianoacrylate adhesive.
