一种防脱出易制作义眼台的研制

目的探讨一种新型简易防脱出的义眼台的制作方法与效果。方法根据眼球摘除后的解剖特点设计义眼台大小,选择聚甲基丙烯酸甲酯和涤纶布为材料制作复合材料义眼台,并对6只家兔行眼球摘除后置入义眼台,经HE染色观察及肉眼观察术后不同时间置入物与眼周围组织的解剖关系。结果聚甲基丙烯酸甲酯部分与组织无黏连,涤纶布形成牢固黏连,周围有纤维组织长入并包绕,义眼台无脱出、移位。结论以聚甲基丙烯酸甲酯和涤纶布为材料制作复合义眼台,方法简易,效果可靠,组织相容性好,术后反应轻,值得在临床上推广使用。

The study of a kind of antiprolapsed orbital implant

Objective To explore the material and evaluate the effect of a kind of antiprolapsed orbital implant. Methods According to the postoperative anatomic characters after ophthalmectomy, the size of the orbital implant was designed and the polymethyl methacrylate and dacron cloth were chosen as the materials for making the robital implant. Six rabbits were operated the ophthalmectomy and orbital implant. The relationship of the orbital implant and ocular tissues around were observed by naked eye and HE staining at the different time. Results Many fibrous tissues rounded and invaded the polymethyl methacrylate which mostly adhered to tissues around, and the dacron cloth which formed adherence completely so that the orbital implant could not move out and displace. Conclusion The polymethyl methacrylate and dacron cloth are the better materials, the antiprolapsed comlex orbit implant for making with better histocompatibility and slight inflammatory reaction, and it is worth popularizing in the clinic.
