【摘要】 目的比较常规连续模式超声乳化术与爆破模式冷超声乳化术治疗白内障的临床疗效。方法选取2009年3月至2010年9月我院收治的234例(234眼)白内障患者为研究对象,随机分为试验组(120例)和对照组(114例),试验组行爆破模式冷超声乳化术,对照组行常规连续模式超声乳化术。观察两组患者术中乳化时间,比较两组患者术后1d、1周的视力及角膜内皮细胞密度,同时比较两组手术并发症的发生率。结果试验组术中乳化时间为(17.1±5.2)s,对照组为(53.3±8.4)s,试验组明显短于对照组,差异有显著统计学意义(P<0.01)。试验组术后1d视力≥0.5的患者比例以及术后1周视力≥0.8的患者比例均明显高于对照组,差异均有统计学意义(均为P<0.05)。两组术前角膜内皮细胞密度比较,差异无统计学意义(P>0.05);与术前比较,两组术后1d、1周角膜内皮细胞密度均降低,差异均有统计学意义(均为P<0.05);两组术后1d、1周角膜内皮细胞密度组间比较,试验组高于对照组,差异均有统计学意义(均为P<0.05)。试验组并发症发生率明显低于对照组,差异有统计学意义(P<0.05)。结论相对于连续模式超声乳化术,爆破模式超声乳化术可显著降低能量使用,缩短超声时间,使各种手术并发症的发生几率降低。更多还原

【Abstract】 Objective To compare the clinical effects of conventional continuous mode phacoemulsification and burst mode cold phacoemulsification for cataract.Methods From March,2010 to September,2010,234 patients(234 eyes) with cataract in our hospital were selected as the objects.All the patients were randomly divided into experimental group(120 cases) and control group(114 cases),burst mode cold phacoemulsification and conventional continuous mode phacoemulsification were performed,respectively.The intraoperative emulsifying time of two groups were observed,the visual acuity and corneal endothelial cell density at postoperative 1 day and 1 week between two groups were compared,and the postoperative complications were also compared.Results The intraoperative emulsifying time in experimental group and control group were(17.1±5.2)s and(53.3±8.4)s,there was significant difference(P<0.01).The proportion of patients with visual acuity equal to or more than 0.5 at postoperative 1 day and equal to or more than 0.8 at postoperative 1 week in experimental group were obviously higher than those in control group,there were statistical differences(all P<0.05).There was no statistical difference in preoperative corneal endothelial cell density between two groups(P>0.05).Compared with pre-operation,the postoperative corneal endothelial cell density at 1 day and 1 week of two groups were all decreased,there were statistical differences(all P<0.05).The postoperative corneal endothelial cell density at 1 day and 1 week in experimental group were higher than those in control group,there were statistical differences(all P<0.05).The complication incidence in experimental group was obviously lower than that in control group,there was statistical difference(P<0.05).Conclusion Burst mode cold phacoemulsification is superior to conventional continuous mode in clinical effects,the intraoperative emulsifying time can be shortened significantly and the postoperative complications incidence is lower.更多还原
