Background: Ocular defects post-enucleation can be rehabilitated using stock or custom ocular prostheses. The stock ocular prosthesis was premade, thus limited in color, shape, size, and iris orientation. Whereas custom ocular prosthesis provides a better aesthetic and fit with good motility, if it is large and heavy, it can burden the lower eyelids and cause lid laxity. In the following case, the ocular prosthesis volume was 4.5mL, which exceeded the ideal volume of 2.2mL. Objectivess: Fabricating hollow using chocolate to reduce weight without affecting the shape and aesthetics of the custom ocular prosthesis. Case Report: A 30-yearold man presented to the Dental Hospital of Sumatera Utara with a chief complaint of unmatching colour, iris disorientation, and minimal motility with the present stock ocular prosthesis post-enucleation. The initial impression was carried out and the scleral wax volume was 4.5mL. The custom occular prosthesis fabrication was done by utilizing chocolate as a hollow matrix. The chocolate matrix was made by placing wax relief on both parts of the mold, then filled with melted chocolate, and after setting, the wax was replaced with scleral acrylic. The chocolate matrix was moldable, had a high density, so it was stable under pressure during acrylic packing, evacuated easily and resulted in an even thickness of acrylic. Conclusion: Fabrication of custom hollow prosthesis eyes with a chocolate matrix obtains a comfortable, aesthetic, lightweight ocular prosthesis and optimum motility.
