超声乳化手术对年龄相关性白内障患者泪膜的影响分析

目的观察白内障超声乳化手术对年龄相关性白内障患者泪膜的影响。方法选择行白内障超声乳化术的年龄相关性白内障患者75例（80只眼）。分别于术前2d和术后1、7d、1、3个月观察患者主观干眼症状、泪膜破裂时间（BUT）、角膜荧光素染色及下睑中央泪河高度的变化情况。结果与术前相比,干眼症状在术后1、7d增加,BUT在术后1、7d、1个月明显缩短,角膜荧光素染色在术后1、7d明显增高,差异均有统计学意义;术后3个月时主观干眼症状、BUT、角膜荧光素染色及下睑中央泪河高度恢复至术前水平,与术前比较差异无显著性。结论白内障超声乳化手术可在短期内影响泪膜的稳定性,应该进行积极地预防及治疗。

Effect of phacoemulsification on tear film of patients with age-related cataract

Objective To observe the effect of phacoemulsification on tear film of patients with agerelated cataract .Method 75casesofpatientswithagerelatedcataractgivenphacoemulsification（80eyes）wereselected.Inthepreoperative2dand postoperative 1 ,7 d ,1 months ,3 months ,subjective symptoms of dry eye ,tear breakup time （BUT） ,corneal fluoresceinstaining and lower eyelid central tears river height changes were observed .Results compared with the preoperative ,postoperative dry eye symptoms in 1d ,7d increased ,breakup time of tear film after 1 d ,7 d ,1months shortened obviously ,corneal fluorescein staining in the postoperative 1d ,7d significantly increased ,differences were significant ;3 months after operation the subjective xe rophthalmia like ,tear breakup time （BUT） ,corneal fluorescein staining and lower eyelid central tears river height recovered to the preoperative level ,compared with those before operation had no significant difference .Conclusion phacoemulsification can influence the stability of tear film in the short time ,which should been actively prevented and treated .
