In a retrospective clinical study, 49 anophthalmos patients were examined, who during the period between 1989 and 1995 had been provided after enucleation with either a sclera-coated silicon (n=26) or hydroxyapatite spheres (n=23). Aim of the investigation was to enable a postoperative comparison between intensity of enophthalmos, motility of artificial eye and implantation, local findings of the microscopic slit-lamp examination, and subjective and objective tolerance. The average observation time was 4,2 years for silicon and 1,8 years for hydroxyapatite implantation.

In contrast to the silicon implantation, there was significantly greater horizontal motility after hydroxyapatite implantation. Vertical motility and intensity of enophthalmos were not significantly divergent. Neither did the subjective satisfaction after questioning differ significantly in the statistics.

Complication-free healing processes were found in 88% of cases after hydroxyapatite implantation, and in 67% of the patient group with silicon prosthesis implantation. A post-enucleation socket syndrome occurred in 2% of silicon implantations, but in no case of hydroxyapatite implantation.

In this clinical study, a postoperative comparison showed better tolerance, healing processes with less complications and better horizontal motility of the artificial eye after the implantation of hydroxyapatite after enucleation than in the patient group after silicon prosthesis implantation.
