摘要
目的前瞻性研究白内障超声乳化术后泪膜及眼表的变化。方法选取连续就诊手术的白内障患者共52例67眼,分为两组,A组为术前存在干眼症患者,共9例12眼;B组为术前无干眼症患者,共43例55眼。两组患者均行上方角膜缘蓝线自闭式隧道切口超声乳化术联合后房型折叠式人工晶状体植入术。分别于术前第1天,术后第1天、第2天、第7天、第30天进行干眼症相关症状调查、无麻醉下泪液分泌试验(Schirmer试验)、泪膜破裂时间(break-uptime,BUT)、角膜荧光素染色检查并积分,比较各项结果在术后不同时间与术前的差异以及手术对两组患者影响程度的差异。结果两组患者分别与术前比较,术后不适主诉增加。Schirmer试验值在术后第1天和第2天明显高于术前,BUT在术后第1天、第2天和第7天较术前缩短,角膜荧光素染色积分在术后第1天、第2天高于术前,差异均有显著性(P<0.05)。结论白内障超声乳化术可在短期内影响患者的泪膜和眼表。
Objective To evaluate the effects of phacoemulsification,on tear film and eye surface. Methods This clinical trial involved 52 patients （67 eyes） with cataracts of any type., who were divided into two groups. There were group A （9 patients 12 eyes with dry eye idsease） and group B （43 patients of 55 eyes without dry eye disessse）. All eyes underwent phacoemulsification through a superficial blue supperficial blue line incision. Symptoms of dry eye disease, tear film break-up time （BUT）, Schirmer＇s I test without topical anesthesia, corneal fluorescein staining were tested preoperatively, and also on the 1st day, 2nd day, 7th day, 30th day pastoperatively. Comparison was made between the tests and the effect of the surgery between the two groups was been compared and analyzed.Results In both groups, patients＇ postoperative cornplatinsts of dry eye greatly increased compared to the preoperative ones. On the 1st day and the 2nd day postoperativdy, the main value of Schimer＇s I test and corneal fluorescein staining scores inereased. BUT reduced on the 1st day, 2nd day, 7th day postoperativdy. All the difference above-mentioned was statistically significant （ P 〈 0.05 ）. Concluslon Phacoemlusifieation significantly alters tear film of all patients in a short term postoperatively.
