Orbital Implantation Techniques and Anophthalmic Socket Management

Orbital implantation and anophthalmic socket management address the restoration of orbital volume, globe motility and aesthetic outcome following removal of an eye. Surgical removal may take the form of enucleation, in which the entire globe is excised, or evisceration, where intraocular contents are removed while preserving the scleral shell and extraocular muscles. In either case, placement of an orbital implant reconstitutes lost volume and provides mechanical linkage for a prosthetic eye. Early implants were simple non-porous spheres, but advances have introduced porous ceramics and polymers engineered to encourage fibrovascular ingrowth, reducing risks of migration and extrusion while enhancing prosthetic motility. Implant wrapping and reinsertion of extraocular muscles further stabilise the construct. Complications such as infection, exposure or socket contracture demand tailored socket management techniques, including fornix deepening procedures and the use of autologous grafts. Recent efforts focus on novel biomaterials with antibacterial and angiogenic functionalities, in situ mouldability for optimal fit, and personalised implants fabricated via additive manufacturing. Comprehensive care integrates surgical innovation with postoperative socket rehabilitation to ensure a stable, comfortable prosthetic environment and long-term aesthetic success.
