超声乳化与小切口非超声乳化治疗白内障的疗效及安全性比较

目的比较分析超声乳化与小切口非超声乳化治疗白内障的疗效及安全性。方法选择90例(117眼)白内障患者,根据手术方式不同分为实验组与对照组,其中实验组采用超声乳化手术,对照组采用小切口非超声乳化手术。比较两组患者的手术治疗效果及术中、术后并发症情况。结果实验组术后1d、7 d、1个月裸眼视力>0.5患者明显多于对照组(χ2=4.24、3.92、5.69,P<0.05)。两组患者术后7 d角膜散光度均高于术前(P<0.01)。实验组术中及术后并发症发生率少于对照组(χ2=4.89,P<0.05)。结论采用超声乳化治疗白内障能取得更好的疗效,患者术后视力恢复更佳,术中及术后并发症少,是一种安全有效的手术方式。

Curative effect and security comparison of ultrasonic emulsification and small incision non-phacoemulsification in threatment of cataract

Objective To discuss curative effect and security comparison of ultrasonic emulsification and small incision non-phacoemulsification to treat cataract. Methods 90 cases （117 eyes）of patients with cataract were divided into experimental group and control group in accordance with different operation methods. The patients in experimental group were given ultrasonic emulsification operation,while the patients in control group were given small incision non-phacoemulsification operation.Operational curative effect and intraoperative and postoperative complication of patients in two groups were compared. Results The number of patients in experimental group,whose naked vision were more than 0.5 after one day,7 days and one months upon the operation was much more than that in control group （x2= 4.24,3.92,5.69,P〈0.05）. The corneal astigmatism of patients in two groups after 7 days ＇ operation was highter than that before the operation（P〈0.05）. The intraoperative and postoperative complication occurrence rates of patients in experimental group were much lower than those in control group （X2=4.89 ,P〈0.05）. Conclusion Ultrasonic emulsification has reliable curative effect on cataract, which can make better vision recovery of patients after the operation, with little intraoperative and postoperative complication, and is a safe and effective operation.
