目的:了解超声乳化白内障吸除术后干眼的发生、发展及防治情况。方法:随机抽取50例(72只眼)于术前3 d、术后1 d、1周、1个月、3个月及0.5 a观察角膜荧光素染色、泪膜破裂时间(breakup time,BUT)及基础泪液分泌试验(Schirmer test I,ST I)。结果:术后患者可出现干眼症状、角膜荧光素染色加重、BUT变短、ST I减少。结论:超声乳化白内障吸除术可影响泪膜的稳定性,部分患者出现明显的干眼症,应及时有效地干预和治疗。
Objective: To understand the occurrence, development and prevention of dry eye after phacoemulsification. Methods: Fifty eyes (72 eyes) were randomly divided into 3 groups: corneal fluorescein staining, breakup time (BUT), postoperative day 1, postoperative 1, postoperative 1, ) And basal tear secretion test (Schirmer test I, ST I). Results: Postoperative dry eye symptoms may occur, corneal fluorescein staining increased, BUT shorter, ST I decreased. Conclusions: Phacoemulsification can affect the stability of tear film, and some patients have obvious dry eye syndrome. It is necessary to timely and effectively intervention and treatment.
