A major focus of research and development in the last couple of decades is the newer materials for orbital implant. Porous materials are preferred primarily because of vascularization and integration that occur. These implants are less likely to migrate than silicone or PMMA implants and are associated with better prosthesis motility especially when coupled with a peg. However, porous implants are significantly more expensive and are associated with higher rates of exposure than traditional non-integrated implants. Wrapping or “capping” of these implants appears to reduce the exposure rate to acceptable levels. Implant size is crucial and should be customized. Muscle attachment provides excellent results in patients who do not wish to consider a motility peg placement.
