白内障超声乳化联合人工晶体植入手术后泪膜的变化

The Changes of Tear Film after Phacoemulsification Combined with Intraocular Lens Implantation

目的观察白内障超声乳化联合人工晶体植入手术对泪膜的影响。方法对48例(60只眼)白内障患者行超声乳化联合人工晶体植入术,观察术前3 d,术后1 d、1周、1个月、3个月的主观干燥异物感,角结膜荧光素染色试验,基础泪液分泌试验(Schirmer Ⅰ test,SIT),泪膜破裂时间(breaking up time,BUT)情况。结果术后1 d、1周、1个月术眼角膜荧光素染色积分、SIT、BUT与术前相比,差异均有统计学意义(P<0.05);术后3个月仅有3例患者仍有明显的干燥感、烧灼感、异物感,与术前相比,各指标差异均无统计学意义(P>0.05)。结论白内障超声乳化联合人工晶体植入术可在短期内影响患者泪膜功能,导致部分患者出现明显的干眼症状和体征。

Objective To observ the changes of tear film after phacoemulsification combined with intraocular lens implantation.Methods Forty-eight cases（60 eyes） with age-related cataract who underwent phacoemulsification combined iwth intraocular lens implantation were chosen and the subjective complaints of dry eye,tear break-up time（BUT）,corneal fluorescein staining and Schirmer I tset（SIT）value were analyzed preoperatively and 1 day,1 week,1 month and 3 months postoepratively.Results Comparing with the data before operation,the complaints、SIT and BUT,corneal fluorsecein staining scorse were all of statistical significance on the first day、1 week and 1 month after operation rsepectively（P〈0.05）,3 months after operation only three patients still have dry eye syndrome,they had no statistical significance（P〉0.05）.Conclusion The tear film have a significant changes in a short period after phacoemulsification combined with intraocular lens implantation,and some patients may have dry eye syndrome after surgery.
