Wladis EJ, et al. - In keeping with increasing surgeon preference for porous implants, most studies identified in this literature search included the utilization of this type of implant. These implants resulted in excellent motility after enucleation surgery, albeit many studies did not evaluate this outcome. Regardless of implant type, major complications were rare, and infection was exceptionally uncommon after enucleation. Given the paucity of data on motility and the absence of direct, objective comparisons of porous and nonporous implants, definitive conclusions about the effect of implant material on motility cannot be made. Since few studies assessed nonporous implants, direct comparisons cannot be made definitively between implant types, and future investigations are needed to enable a critical evaluation.
