目的探讨聚甲基丙烯酸甲酯(polymethylmethacrylate,PMMA)义眼片在因眼外伤、眼肿瘤等原因导致的后天性眼球缺失美容中的应用。方法总结分析8年内应用PMMA材料,根据患眼的具体情况,依据健眼的特征定制和佩戴义眼的效果。结果1155例应用PMMA材料制作的义眼,无排斥反应,在色泽度、透明度上能与健眼媲美,联合羟基磷灰石义眼台置入能达到仿真活动的效果。结论PMMA是目前最理想的义眼片制作材料,在羟基磷灰石义眼台置入手术联合活动型PMMA义眼片制作,已可以达到以假乱真的效果。
Objective To investigate the application of polymethylmethacrylate (PMMA) eyelid in the cosmetic treatment of acquired orbital eye drop caused by ocular trauma, eye tumor and so on. Methods To summarize and analyze the application of PMMA materials within 8 years, according to the specific conditions of the affected eye, according to the characteristics of eye health and wearing eye effect. Results 1155 cases of PMMA material made of prosthetic eye, no rejection, in the degree of color, transparency and eye health comparable to the combined hydroxyapatite Yi Zhuang placement can achieve the effect of simulation activities. Conclusion PMMA is the most ideal material for the production of prosthetic eyelids. PMMA has been used in the production of hydroxyapatite artificial eye prosthesis combined with movable PMMA prosthetic eye pieces.
