双向线性超声乳化技术对糖尿病白内障的治疗价值

Phacoemulsification by dual linear control energy and vacuum treatment for diabetic cataract

目的探讨双向线性超声乳化技术对糖尿病白内障的治疗价值。方法选取我院2009年5月—2011年5月收治糖尿病白内障患者100例,采用随机数字表法分为两组,其中对照组50例,采用单向线性能量控制+负压技术治疗;双向线性超声乳化组50例,采用双向线性动态能量控制+负压技术治疗;比较两组患者超声相对能量复合参数及术中术后并发症发生情况等。结果对照组和双向线性超声乳化组患者核硬度Ⅰ度、Ⅱ度超声相对能量复合参数组间比较无统计学差异(P>0.05);而在核硬度Ⅲ度、Ⅳ度患者中,双向线性超声乳化组患者超声相对能量复合参数均明显低于对照组(P<0.05);双向线性超声乳化组患者术中后囊破裂发生率明显低于对照组(P<0.05);同时双向线性超声乳化组患者术后角膜水肿程度也明显优于对照组(P<0.05)。结论相较于单线线性超声乳化技术,双向线性超声乳化技术应用于糖尿病白内障患者治疗能够有效减少超声乳化使用能量及术中术后并发症发生风险。

Objective To investigate thetherapeutic value of phacoemulsification by dual linear control energy and vacuum treat- ment on diabetic cataract patients. Methods A total of 100 patients with diabetic cataract were chosen in the period from May 2009 to May 2011 in our hospital and randomly divided into two groups, i.e. control group （n = 50） treated with single linear con- trol energy and vacuum treatment and dual linear phacoemulsification group （ n = 50） treated with dual linear control energy and vacuum treatment. Comparison on uhrasound relative energy complex parameters and intra-and postoperative complications was done between the two groups. Results There was no significant difference in ultrasound relative energy complex parameters in the pa- tients with nuclear hardness of scale I and I1 between the two groups （P 〉 0.05）. The parameters in those with nuclear hardness of scale 111 and IV were significantly lower in the dual linear phacoemulsification group than in the control group （ P 〈 0.05 ）. Intraop- erative posterior capsule rupture incidence of the dual linear phaeoemulsification group was significantly lower than that of the control group （ P 〈 0.05 ）. Postoperative corneal edema of the dual linear phacoemulsification group was significantly milder than that of the control group （ P 〈 0.05 ）. Conclusion Compared with that by single linear control energy and vacuum, the phacoemulsification by dual linear control energy and vacuum treatment on diabetic cataract patients can efficiently reduce the energy of emulsification, and therefore decrease the risk of intra-and postoperative complications.
