方法：随机选取2014-01/05在我院行白内障手术的患者63例63眼，根据不同手术方式分为两组，A组行小切口非超声乳化联合人工晶状体植入术31例31眼，B组行常规白内障超声乳化联合人工晶状体植入32例32眼，观察两组患者术后1，3mo的主观症状、泪膜破裂时间(BUT)、Sehirmer Ⅰ试验等情况。

结果：两组术后1mo干眼症状较术前明显增加、BUT缩短，SⅠt降低，且两组间比较差异有统计学意义(P<0.05)； 术后3mo时干眼症状仍然存在，但SⅠt及BUT程度基本恢复至术前水平，两组间与术前比较差异无统计学意义(P>0.05)。

结论：两种手术方式均可在短期内影响患者泪膜功能，白内障超声乳化手术较小切口非超声乳化手术术后引起干眼的程度相对较轻，在泪液功能的改变上前者轻于后者，但随着时间的推移这种差异性降低。

METHODS: Sixty-three case(63 eyes)with age-related cataract who received cataract surgery in our hospital from May to July 2014 were randomly divided into two groups: 31 cases(31 eyes)with small incision non-phacoemulsificatian cataract extraction combined with intraocular lens implantation in group A, 32 case(32 eyes)with phacoemulsificatian combined with intraocular lens implantation in group B. The subjective complains of dry eye, tear break-up time(BUT)and Schirmer Ⅰ test(SⅠt)were measured preoperatively and 1 and 3mo postoperatively.

RESULTS: One month postoperative, dry eye symptoms increased significantly compared with the preoperative, BUT shortened, SⅠt reduced. There was significant difference between the two groups and compared with the preoperative(P<0.05). After 3mo, dry eye remains existed, but the extent of SⅠt and BUT recovered to preoperative levels. There was no significant difference between the two groups and compared with the preoperative(P>0.05).

CONCLUSION: The tear film stability of patients with two surgical procedures reduces in the short term. Compared with patients with phacoemulsificatian, the degree of dry eye of patients with small incision non-phacoemulsificatian is more severe, the tear function changes come to more light on the former. But this difference will reduce with the passage of time.
