Abstract：Objective:To analyze the effect of modified self pickup amniotic membrane preservation operation on patients with recurrent pterygium.Method:Sixty-eight patients(68 eyes)with recurrent pterygium treated in the Affiliated Sanming First Hospital of Fujian Medical University from January 2021 to June 2023 were retrospectively selected.According to different surgical methods,they were divided into group A(32 cases,32 eyes)and group B(36 cases,36 eyes).Group A received conventional amniotic membrane transplantation operation and group B received modified self pickup amniotic membrane preservation operation.The relevant indexes,the dry eye condition before surgery and 1 week,1 month and 2 months after operation,the satisfaction of operation of the two groups were compared.Result:On the first day after operation,the incidence of corneal irritation symptoms in group B was lower than that in group A,and the complete healing time of corneal epithelium was shorter than that in group A,the differences were statistically significant(P<0.05).There were no significant differences in preoperative non contact tear film break-up time(nBUT),Schirmer Ⅰ test(SⅠt)between the two groups(P>0.05).At 1 week and 1 month after operation,nBUT and SⅠt in group B were higher than those in group A,and the differences were statistically significant(P<0.05).There were statistically significant differences in nBUT,SⅠt,time,intergroup,time×intergroup between the two groups(P<0.05).The surgery satisfaction of group B was higher than that of group A,the difference was statistically significant(P<0.05).Conclusion:Modified self-preservation amniotic membrane operation can significantly improve postoperative corneal irritation symptoms in patients with recurrent pterygium,promote the repair of corneal injury,improve patients'dry eye,reduce postoperative discomfort,and increase patient satisfaction.However,long-term postoperative dry eye improvement remains to be further observed.
