New magnetic ocular obturator, series III, MK. I: completely buried, enucleation model.

چکیده
THIS is a preliminary report of a new magnetic ocular obturator for use after enucleation of the globe. It is a completely buried implant. An attempt has been made to bring the research, design, construction, and surgery of the new instrument into continuity with previous models of the post-eviscerative type, some partially buried and some wholly buried within the orbital structure, applying the experience already gained. For those unacquainted with this line of implant research, a brief classification is given below:

ß-tricalcium Phosphate Granules as an Alternative Material for Ocular Implantation
Background: Some types of implants used for orbital implantation have side effects and complications. In this study we have evaluated beta-tricalcium phosphate (ß-TCP: ChronOS) granules as an orbital implant. Methods: Eighteen rabbits randomly allocated to four groups. Right eye enucleation performed in groups I to III followed by filling with autologous bone particles (n=5), a mixture of autol...

متن کاملExtra-conjunctival Implants.
To the Editorial Committee of the BRITISH JOURNAL OF OPHTHALMOLOGY SIRS-The technique described by Nairac (1954) is ingenious, but founded upon a doubtful principle. Most authorities on orbital implants (movable ocular prostheses) agree that, to stand a chance of being retained for more than 5 years, an implant must be completely enclosed in both Tenon's capsule and the conjunctiva (Choyce, 195...
متن کاملBuried orbital implant with extraconjunctival extension.
THE diversity of types of orbital implants suggests that the ideal one is still to be found. In the present stage of our knowledge it appears that the best retained are those which are completely buried. On the other hand the movements of the artificial eye are more natural if there is direct contact between implant and prosthesis. Work on the implant described below was begun in 1953 at the Co...
