自闭式巩膜隧道小切口白内障手术后角膜水肿的观察

目的 观察自闭式巩膜隧道小切口白内障手术后角膜水肿的发生率,并分析发生原因.方法 以我院收治的108例（113只眼）安徽省霍山县民生工程贫困白内障患者为研究对象,所有患者均采用自闭式巩膜隧道小切口现代囊外摘除联合人工晶体植入术治疗.统计患者术后1d、3d、1周、1个月角膜水肿的发生率,并分析发生原因.结果 本组108例（113只眼）患者行手术治疗后,术后1d、3d、1周、1个月角膜水肿的发生率依次为10.6％、7.08％、0.88％、0.患者术后发生角膜水肿的原因主要有：大核硬核,器械损伤,内切口靠前、娩核困难,灌注液压力过高、暂时性眼压升高.结论 自闭式巩膜隧道小切口白内障手术后角膜水肿的发生率较低,通过提高手术技巧有利于降低术后角膜水肿的发生率.

Observation on the corneal edema after the operation of self-sealing scleral tunnel small incision cataract exaction

Objetive To observe the corneal edema after the operation of self-sealing scleral tunnel small incision cataract exaction and analyze the reason. Methods 108 cases （113 eyes） of cataract were treated with scleral tunnel small incision extracapsular cataract extraction combined with intraocular lens implantation. Corneal edema at 1 day, 3 days, 1 week and 1 month after the operation was analyzed. Results The rate of corneal edema at 1 day, 3 days, 1 week and 1 month after the operation was 10.6%, 7.08%, 0.88%, 0, respectively. The main reasons included large and hard nucleus, equipment damage, central incision, difficulty in the nuclear delivery, perfusion pressure is too high, transient rise of IOP. Conclusion It was relatively low for the rate of croneal edema after the operation of self-sealing scleral tunnel small incision cataract exaction. Improving the operation skills could reduce the incidence of postoperative corneal edema.
