Patient-Specific Orbital Implants Vs. Pre-Formed Implants for Internal Orbital Reconstruction
Seminars in Ophthalmology, 2023To compare the outcome of orbital blowout fracture repair by means of pre-formed porous-polyethylene titanium implants (PFI) vs patient-specific porous-polyethylene implants (PSI).Retrospective cohort study. Baseline characteristics, ophthalmic examination results, ocular motility, fracture type, the timing of surgery, implant type, and final relative ...

Archives of Ophthalmology, 1941
The tolerance of the orbital tissue to foreign materials has always been well known, and for this reason many substances have been implanted in Tenon's capsule. Most ophthalmologists of the present day concede that something should be put into the socket after enucleation in order to obliterate the unnatural folds and depressions in the upper and lower

Resorbable Implant for Orbital Defects
American Journal of Ophthalmology, 1982Tricalcium phosphate ceramic, a synthetic bone substitute, was inserted into defects created in the inferior orbital rims of 18 rabbits. The animals were killed after three, eight, 24, and 40 weeks. Early sections demonstrated encapsulation with fibrous ingrowth.

Autogenous Dermis-Fat Orbital Implantation
Archives of Ophthalmology, 1983We examined 52 consecutive patients who underwent autogenous dermis-fat implantation in anophthalmic sockets during the past five years. The results of the study show that 81% of the cases had no change in the volume of the graft during a mean follow-up period of 2 1/2 years, ranging from a minimum of six months to a maximum of five years.

A NEW MAGNETIC ORBITAL IMPLANT
Archives of Ophthalmology, 1954INCREASING dissatisfaction with the results obtained after enucleation and the insertion of a glass or plastic sphere implant led to efforts to improve these results by changing the character of the implant and making associated changes in the artificial eye. This work was possible only because our Plastic Artificial Eye and Restorations Clinic had the

Orbital implants for fracture repair
Current Opinion in Ophthalmology, 2011To review the latest advancements in implant materials for orbital fracture repair, including analysis of the last year in research.Advances in the manufacture of highly biocompatible alloplastic materials offer an alternative to traditional autologous implants for orbital fracture repair. The emergence of the composite implant offers the stability and

Orbital implants: potential new directions
Expert Review of Medical Devices, 2006This article reviews orbital implants used to replace an eye after enucleation or evisceration. Advantages of implant placement are described, with discussion of implant and wrap material, and design features that affect clinical outcomes. Implants may be porous or nonporous, pegged for linkage with a cosmetic shell or unpegged, and may be wrapped with

Complications of Supramid Orbital Implants
Ophthalmic Plastic & Reconstructive Surgery, 2003To determine the incidence and risk factors of complications associated with Supramid orbital implants.A retrospective chart review was performed to document complications in a series of 41 patients receiving Supramid implants during orbital reconstruction or fracture repair.

Pegging the Porous Orbital Implant
Ophthalmic Plastic & Reconstructive Surgery, 2011Hydroxyapatite (HA) orbital implants are commonly used for the anophthalmic socket. With a HA implant, if motility is not satisfactory then a peg system can be surgically placed in attempts to improve motility. The authors report the technique and results of 83 patients who received motility peg placement over an 8-year period by a single surgeon ...

MRI of orbital hydroxyapatite implants
Neuroradiology, 1996Our aim was to use MRI for the postsurgical assessment of a new form of integrated orbital implant composed of a porous calcium phosphate hydroxyapatite substrate. We studied ten patients 24-74 years of age who underwent enucleation and implantation of a hydroxyapatite ball; 5-13 months after surgery, each patient was examined by spinecho MRI, with fat
