方法：对我院2014-05/2015-10期间眼科门诊实施白内障超声乳化吸除联合人工晶状体植入术的年龄相关性白内障患者145例145眼，术前3d，术后1wk，1、3、6mo进行眼部检查。检查项目包括：(1)眼表疾病指数问卷；(2)泪河；(3)角膜荧光素染色；(4)泪膜破裂时间(BUT)；(5)泪液分泌试验(Schirmer Ⅰ test，SⅠt)。

结果：年龄相关性白内障患者超声乳化吸除联合人工晶状体植入术后可出现干眼症状及体征，如泪河线变窄，BUT缩短、SⅠt值下降，角膜荧光素染色着色。此现象可在术后1wk即可出现，术后1mo时达到最明显的状态，持续至术后3mo，术后6mo部分患者的症状可有一定程度恢复。

结论：老年人由于其特殊生理特点，超声乳化吸除联合人工晶状体植入术后30d出现严重的干眼，之后可缓慢恢复。应适时给予预防和治疗， 从而提高患者的眼部舒适度及视觉质量。

METHODS: Samples were collected from 145 age-related cataract patients(145 eyes). Dry eye was analyzed at 0, 7, 30, 90 and 180d after phacoemulsification by 1)Ocular Surface Disease Index questionnaire(OSDI), 2)tear meniscus height(TMH), 3)corneal fluorescein staining, 4)tear film break-up time(BUT), 5)Schirmer Ⅰ test(SⅠt).

RESULTS: The symptoms and signs of dry eye, such as narrowing of TMH, shorting of BUT, decreasing of SⅠt, cornea staining by fluorescein, occurred as early as 7d post-phacoemulsification and were measured by OSDI questionnaire and 4 additional clinical tests. Over the six-month observation the severity of dry eye peaked at 30d and then gradually relieved.

CONCLUSION: The severity of dry eye after phacoemulsification peaked at 30d and gradually improved over time. Considering the characteristics of ocular surface for aged people ophthalmologists should pay more concern on evaluating the occurring of dry eye after phacoemulsification so as to improve the life quality of these people.
