摘要:

目的:评价不同材料制成义眼台在眶内植入的临床效果、并发症和应用情况及不同植入方法对避免术后并发症所起的作用。
方法:采用电子检索的方式在万方数据库中检索1999-01/2009-12有关义眼台植入的研究,关键词为“眼科新材料的生物相容性”。排除重复研究、普通综述或Meta分析类文章,筛选纳入38篇文献进行评价。
结果:目前眶内植入材料主要有天然珊瑚羟基磷灰石义眼台、多孔生物陶瓷义眼台、聚甲基丙烯酸甲酯义眼台和改性PHEMA多孔水凝胶义眼台等。其中天然珊瑚羟基磷灰石义眼台应用临床效果较好,但因其价格昂贵等原因,不少研究人员正在研究此种材料的替代品。同时义眼台植入方法的选择对避免术后并发症的发生起到很大作用,很多研究文章提出了有价值的成果。
结论:用于制作义眼台的材料选择很多,植入方法有多种,在实际操作中,应根据患者实际情况采取相应的措施,以达到最满意的效果。

Abstract:

OBJECTIVE: To evaluate the clinical effect, complications and applications of artificial eye mount made of different materials in orbital implant, as well as the influence of different implantation approaches to avoid postoperative complications.
METHODS: An online search of Wanfang database was performed for articles related to artificial eye mount from January 1999 to December 2009, with key words of “biocompatibility of new ophthalmology materials” in Chinese. Duplicated research, reviews or Meta analysis were excluded, finally 38 articles were evaluated.
RESULTS: At present, the orbital implants are mainly artificial eye mounts made of natural coralline hydroxyapatite, porous bioceramic, polymethyl methacrylate and modified PHEMA porous hydrogel. Natural coralline hydroxyapatite shows better clinical application as an orbital implant, but its high cost makes many researchers being studying a substitute material. At the same time, the approach of orbital implantation plays a significant role in avoiding the occurrence of postoperative complications, many researches demonstrate valuable achievements.
CONCLUSION: There are many materials for producing artificial eye mount, also many implantation means. In practical operation, we should take the appropriate measures based on the actual situation of patients, to achieve the most satisfactory results.
