方法：对2014-09/12间在我院接受超声乳化+人工晶状体植入手术的150例200眼白内障患者，根据有无合并结膜松弛症，分为正常组110例140眼和结膜松弛组40例60眼； 随访3～6mo，观察手术前后两组患者泪膜破裂时间、异物感、泪溢及结膜充血等情况以及上述情况恢复到术前状态所用时间，并进行统计学分析。

结果：超声乳化+人工晶状体植入术后，正常组和结膜松弛组患者泪膜破裂时间(BUT)分别与术前比较，差异有统计学意义(t=20.93、19.16，均P =0.00)，术后两组患者眼部异物感、泪溢情况、结膜充血情况与术前比较差异有统计学意义(均P =0.00)； 比较两组患者BUT、眼部异物感、泪溢和结膜充血等情况恢复到术前状态所用时间，差异有统计学意义(t=17.16、14.18、27.41，均P=0.00)。

结论：超声乳化+人工晶状体植入手术使白内障患者的眼表状况明显变差； 结膜松弛症在白内障术后可显著延迟患者眼表功能的恢复。

METHODS:Totally, 150 cases(200 eyes)of cataract patients accepted phacoemulsification and intraocular lens implantation form September 2014 to December 2014 in our hospital were retrospectively analyzed. All the cases were divided into two groups, normal group(110 cases with 140 eyes)and conjunctivochalasis group(40 cases with 60 eyes)according to coexisted with conjunctivochalasis or not. Follow up lasted 3～6mo. The breakup time(BUT)of tear film, foreign body sensation, epiphora and conjunctival congestion of two groups were observed before and after operation and statistically analyzed. The time, these factors took to recover to preoperative state were observed too.

RESULTS:The differences of the BUT of two groups before and after the operation was statistically significant(t=20.93, 19.16; both P=0.00). The differences of the two groups after operations in terms of ocular foreign body sensation, epiphora and conjunctival congestion had statistical significance(P=0.00). The time these observed factors of two groups took to recover to preoperative state was significantly different(t=17.16, 14.18, 27.41; all P=0.00).

CONCLUSION:The ocular surface conditions are significantly worse after phacoemulsification and intraocular lens implantation in cataract patients. Conjunctivochalasis could significantly delay the recovery of ocular surface function after cataract surgery.
