摘　　要：目的对比研究白内障超声乳化术和现代囊外摘除术后眼表功能的变化。方法选择156例186眼白内障患者,分为两组,分别进行白内障超声乳化联合人工晶体植入术(PHACO组,98例114眼)和白内障现代囊外摘除联合人工晶体植入术(ECCE组,58例72眼)。术后1个月对干眼相关症状、体征、泪液分泌试验(schirmer I试验)、泪膜破裂时间(BUT)、角膜荧光素染色、眼表虎红染色等项目进行检查和评分比较。结果两组间在症状、体征、干眼诊断性试验等各项指标评分上均有显著性差异(P<0.05),ECCE组评分明显高于PHACO组,ECCE组干眼症发病率(27.78%)也高于PHACO组(4.38%),其差别同样具有显著性意义(P<0.05)。结论白内障现代囊外摘除术较超声乳化术在术后短期内更易对眼表功能造成影响,使泪膜稳定性受到破坏而产生干眼症。Objective To evaluate the effect of phacoemulsification and extracapsular cataract extraction on the eye surface. Methods This clinical trial involved 156 patients（186 eyes） with cataract undergoing phacoemulsification （PHACO group, 98cases 114 eyes） or extracapsular cataract extraction（ECCE group, 58cases 72 eyes）. The symptoms and sings of dry eye disease, schirmers I test, break-up time （BUT）, corneal ftuorescein staining, rosebengal staining were tested and marked 1 months after operation, comparison for the results was made between two groups. Results The marks of all the index such as symptom, sings, diagnostic test between two groups had significant difference （P〈0.05）. Marks in ECCE group were singificant higher than those in PHACO group. The rate of dry eye disease in the ECCE group（27.78%） was higher than that in the PHACO group （4.38%） and the difference was also singificant （P〈0.05）. Conclusions In a short term postoperatively, the extracapsular cataract extraction seems more easily to effect the function of eye surface and lead to dry eye disease than phacoemulsification.
