方法：收集2011-08/2012-10间我院眼科收治的老年性白内障患者78例78眼，经颞侧透明角膜切口行白内障超声乳化联合人工晶状体植入术。分别于术前、术后1d； 1wk； 1，3，6mo观察眼表情况，记录眼表刺激症状、角膜荧光素染色、泪膜破裂时间、泪液分泌实验(Schirmer Ⅰ test，SⅠt)，并对数据进行统计分析。

结果：术后1wk内，患者有明显的干眼症状，术后1d； 1wk； 1mo，角膜荧光素着色较术前明显增多，而泪液分泌量明显减少，差异具有统计学意义(P<0.05)，术后3，6mo与术前无明显差异(P>0.05)。术后1mo内泪膜破裂时间较术前明显缩短(P<0.05)，3mo时降至术前水平(P>0.05)并保持至术后6mo。

结论：白内障超声乳化联合人工晶状体植入手术对眼表具有一定程度的影响，临床应积极采取措施进行预防和治疗。

METHODS: Totally 78 cases of 78 eyes with age-related cataract were collected from August 2011 to October 2012, and they underwent corneal incision phacoemulsification combined with intraocular lens implantation. The score of dry eye symptoms; tear breakup time(BUT); Schirmer Ⅰ test(SⅠt)and corneal fluorescein staining were observed and recorded in 3 days before, 1 day, 1 week, 1 month, 3 and 6 months after surgery respectively. The results were analyzed statistically.

RESULTS: All the subjects complained of dry eye within 1 week after surgery. Compared with 3 days before the surgery, the corneal fluorescein staining increased and the amount of tear secretion reduced statistically significant in 1 day, 1 week and 1 month(P<0.05). BUT was significantly shorten in 1 month after surgery(P<0.05). Three months after the operation, they were all recovered to the level of before(P>0.05), and lasted to 3 months later.

CONCLUSION: Phacoemulsification combined with intraocular lens implantation has obvious effect on the ocular surface to some extent. Preventions and treatment should be taken clinically.
