翼状胬肉的手术方法存在许多争议 ,文献报道有多种术式。结膜缺损区域 ,可采取巩膜暴露技术、自体结膜移植及近期发展起来的羊膜移植术。自体结膜移植的术后复发率低 ,并发症极少 ,但需要获取相对大的正常结膜组织。本研究目的是评价生物材料—经过处理的人心包膜 ,应用于复发 There are many controversies about the surgical method of pterygium. There are many kinds of surgical procedures reported in the literature. Conjunctival defect area, can be scleral exposure techniques, autologous conjunctival transplantation and the recent development of amniotic membrane transplantation. Autologous conjunctival transplantation postoperative recurrence rate is low, with minimal complications, but the need to obtain a relatively large normal conjunctiva. The purpose of this study was to evaluate biomaterials - treated human pericardium and applied to recurrence
