Magnetic orbital implants.

Magnetic orbital implants.

Sixty-six consecutive cases undergoing enucleation with the insertion of the Roper-Hall magnetic implant at the Birmingham and Midland Eye Hospital (BMEH) were followed up to re-establish the rate of extrusion. It was possible to study the records of all 66 patients. An extrusion rate of 1.5% was found.

Orbital prostheses anchored by dental implants

Osseointegrated dental implants seem to be applicable for anchoring orbital prostheses in cases of previous extended ablative surgery of the orbit including excenteration of an eye. These implants are applied at stage one and connected with abutments at stage two of a two-stage surgical procedure. Nine Caucasian patients with a total of 25 osseointegrated periorbital dental implants were studie...

Problem of orbital implants after enucleation.

GREAT efforts have been made by ophthalmologists in the last 10 years to design an implant conveying good prosthetic mobility, to offset in part the tragic result of excision. The immediate success of the implants aroused enthusiasm, but subsequent complications, including suppuration and expulsion, have led to further modifications. So frequent were these disappointments in spite of changes in...

Magnetic orbital implant.

THIs implant was developed with the object ofincreasing the degree ofmovement obtained with the Allen type ofburied orbital implant. The satisfactory way in which these implants are retained in the orbit is demonstrated by the large number which have now more than fulfilled the 2-year follow-up period suggested by Choyce (1952). The retention of the magnetic form of implant appears to be as goo...
