老年白内障患者两种手术方式术后干眼的临床分析

目的了解老年白内障患者两种手术方式术后干眼的发病情况。方法对392例（392只眼）单眼老年白内障患者进行分组：A组206例（206只眼）行巩膜隧道切口白内障囊外摘除联合人工晶状体植入术；B组186例（186只眼）行透明角膜切口白内障超声乳化摘除联合人工晶状体植入术。术后观察3个月，比较两组手术方式术后干眼的发病情况。结果术后1d至3个月，小切口囊外摘除术组有20只眼（9．71％）出现了干眼症状，超声乳化组有29只眼（15．59％）出现了干眼症状。结论透明角膜切口的白内障超声乳化术比巩膜隧道的小切口自内障囊外摘除术术后千眼的发病率高。

Clinical analysis of the dry eye of two different surgical strategies for senile cataract

Objective To find out the status of dry eye of two different surgical strategies for senile cataract. Methods 392 cases（392 eyes ） were divided into2 groups. Group A included 206 cases（206 eyes ） and was peformed with cataract extraction through small incision combined with intraocular lens implantation, group B included 186 cases （ 186 eyes ） and was peformed with phacoemulsification with corneal incision combined with intraocular lens implantation. The status of dry eye was determined 3 months after operation. Results 20 eyes （ 9.71% ） had dry eye syndrome in group A, 29 eyes（ 15.59% ） had dry eye syndrome in group B. Conclusion The incidence of dry eye for cataract extraction through small incision was higher than phacoemulsification with corneal incision.
