PURPOSE
To report inflow of extraocular fluid after phacoemulsification with use of sutureless corneal incisions.
DESIGN
Interventional case series.
METHODS
setting: Wilmer Eye Institute, Johns Hopkins Hospital, Baltimore, Maryland. patients: Eight patients (three women), aged 58 to 91 years, showing minimal bleeding from the limbal capillary bed during phacoemulsification. intervention: Surgery was performed through a 2.8-mm limbal incision. External pressure simulating patient manipulation was applied before and after wound hydrosealing with an irrigation cannula. main outcome measures: Inflow of blood-tinged tear fluid into the anterior chamber through the wound was monitored by using digital video.
RESULTS
Inflow of extraocular fluid was observed in all eyes when the cannula was released, even after wound hydrosealing. Two patients showed spontaneous fluid inflow.
CONCLUSIONS
Tested sutureless corneal incisions allow inflow of extraocular fluid into the anterior chamber after phacoemulsification. This may permit intraocular contamination leading to endophthalmitis.
目的
报告使用无缝线角膜切口进行超声乳化白内障吸除术后眼外液的流入情况。
设计
干预性病例系列。
方法
地点：马里兰州巴尔的摩市约翰霍普金斯医院威尔默眼科研究所。患者：8例患者（3名女性），年龄58至91岁，在超声乳化白内障吸除术中角膜缘毛细血管床出血极少。干预措施：通过2.8毫米角膜缘切口进行手术。在使用冲洗套管进行伤口水密缝合前后，施加模拟患者操作的外部压力。主要观察指标：使用数字视频监测带血泪液通过伤口流入前房的情况。
结果
即使在伤口水密缝合后，当松开套管时，所有眼中均观察到眼外液流入。2例患者出现自发性液体流入。
结论
经测试的无缝线角膜切口在超声乳化白内障吸除术后允许眼外液流入前房。这可能会导致眼内污染，进而引发眼内炎。
