小切口非超声乳化白内障摘除人工晶体植入术对眼表的影响

摘要

目的 探讨小切口非超声乳化白内障摘除人工晶体植入术对眼表的影响.方法 选择行小切口非超声乳化白内障摘除人工晶体植入术的年龄相关性白内障患者50例64眼,观察术前、术后1天、1周、1个月、3个月、6个月的主观干燥异物感、基础泪液分泌试验(Schinner I test,SIT)、泪膜破裂时间(breaking up time,BUT)、角膜荧光染色及眼表虎红染色试验,并对数据进行统计学分析.结果 与术前相比,术后1天、1周、1个月术眼有明显干燥异物感、角膜荧光染色;眼表虎红染色试验较术前有明显增多;SIT明显减少,术前(14.67±10.35)mm,术后一周(12.45±6.34)mm;BUT明显缩短,术前(10.56±4.36)s,术后一周(5.35±2.54)s(P<0.05);术后3～6个月术后干燥异物感,角膜荧光染色、虎红染色、SIT及BUT恢复到术前水平,与术前比较差异无显著性(P>0.05).结论小切口非超声乳化自内障摘除人工晶体植入术对眼表具有一定的影响,在短期内影响泪膜功能,导致干眼症.%Objective To evaluate the ocular changes after small incision non-phacoemulsification cataract surgery and posterior chamber intraocular lens ( PC-IOL ) implantation .Methods 64eyes of50cases with age related cataract who underwent small incision non-phacoemulsification cataract surgery and posterior chamber intraocular lens ( PC-IOL Xmplantation were included in this study.The eyes were observed for subjective complaints of dry eye ,tear break up ,corneal fluorescein staining and rosebengal ataining preoperatively and Schirmer I test value were analyzed preoperatively and 1 day , 1 week, 1 month, 3 months and 6monlhs postoperatively. Results Comparing with the data before operation, the subjective complaints of dry eye ,tear break up , corneal fluorescein staining and rosebengal ataining preoperatively and Schirmer I test were all of statistical singificance( P<0.05 )on the first day ,lweek and 1 month after operation respectively, but 3 to 6 months after operation they had no statistical significance ( P> 0.05 ) Conclusion Small incision non-phacoemulsification cataract surgery and PC-IOL implantation have effects on the ocular surface in the short time ,and some patients may have dry eye syndrome after surgery.
