Abstract:

BACKGROUND: With improvement of artificial eye material, the method of artificial eye implantation is critical for artificial eye exposure.
OBJECTIVE: To study a new method of hydroxyapatite (HA) artificial eye implantation with less complications after surgery than the common operation, and to explore the mechanism underlying artificial eye exposure after eye content enucleation and HA artificial eye implantation, so as to elevate the treatment standard.
METHODS: Twenty-five patients were divided randomly into two groups according to surgical approach. In traditional approach group, 14 patients (14 eyes) were treated with eye enucleation and HA artificial eye implantation, while in modified approach group, 11 eyes underwent eye enucleation and double-sclera covered hydroxyapatite implantation in muscle cone. The rates of artificial eye exposure and materials-host reaction were compared and analyzed between two groups.
RESULTS AND CONCLUSION: Artificial eyes of traditional approach group were exposed in 8 cases, and that of modified approach group was exposed in 1 case. There were significant differences between the two group by correct Chi-square test  (χ²=4.264, P=0.039 < 0.05). Modified HA artificial eye implantation is a good method with simple operation and less artificial eye exposure.
