方法：采用随机对照分组的方法将我院手术治疗的原发性翼状胬肉患者99例103眼随机分为A，B 两组。A组为角膜缘上皮移植术组(n=54眼)，采用翼状胬肉切除联合角膜缘上皮移植术； B组为羊膜移植术组(n=49眼)，采用翼状胬肉切除联合羊膜移植术。术后随访1a，以泪膜破裂时间(breaking-up time，BUT)、复发率等指标作为分析参考指标。

结果：术后1a，联合角膜缘上皮移植术组有4眼(7.4%)复发。联合羊膜移植术组有11眼(22. 5%)复发。两组复发率比较，差异有统计学意义(P<0.05)。两组间BUT比较无统计学意义(P>0.05)。

结论：相比羊膜移植术，翼状胬肉切除联合角膜缘上皮移植术治疗原发性翼状胬肉，能更有效的降低术后复发率。

METHODS: There were 99 patients(103 eyes)with primary pterygium. These patients were randomly divided into two groups, group A received limbal epithelial autograft transplantation combined with pterygium excision(n=54)and group B received amniotic membrane transplantation(n=49). All patients were followed up with 1a. Breaking-up time(BUT)of tear film and recurrence rates were observed.

RESULTS: One year after surgery, in the limbal epithelial autograft transplantation group, 4 eyes(7.4%)had recurrence pterygium, in the amniotic membrane transplantation group, 11 eyes(22.5%)had recurrence pterygium, The recurrence rates of the two surgical methods were significantly different(P<0.05). No statistically significant difference was observed between the two groups regarding postoperative tear film BUT(P>0.05).

CONCLUSION: Limbal epithelial autograft transplantation combined with pterygium excision is superior to amniotic membrane transplantation in terms of recurrence rates.
