无缝线小切口白内障囊外摘除术治疗硬核白内障的临床疗效分析

目的观察无缝线小切口白内障囊外摘除术治疗硬核白内障的临床疗效,总结其临床应用价值。方法选取汉中市中心医院眼科于2007年6月至2009年6月收治的268例(433只眼)白内障患者,均采取无缝线小切口白内障囊外摘除术治疗,术前所有的患者患眼均局部点用妥布霉素滴眼液,术后所有患者局部点用复方妥布霉素滴眼液,观察分析治疗效果,进行统计学分析。结果术后1天球镜矫正视力或裸眼视力≥0.5者397只眼(91.7%),术后1周球镜矫正视力或裸眼视力≥0.5者411只眼(94.9%),术后1个月球镜矫正视力或裸眼视力≥0.5者409只眼(94.5%),基本达到稳定水平,术后1天、1周、1个月、3个月的术后球镜矫正视力或裸眼视力比较差异不显著(P>0.05),无统计学意义;患者术后1天、1周、1个月、3个月与术前的角膜散光度数比较术前存在明显差异(P<0.05),具有统计学意义。术中出现后囊膜破裂22只眼(5.1%),出现悬韧带断离27只眼(6.2%),术中并发症发生率为11.3%;术后出现并发症94只眼,发生率为21.7%。结论无缝线小切口白内障囊外摘除术治疗硬核白内障的临床疗效显著,能有效改善球镜矫正视力或裸眼视力,减少并发症发生,安全可靠,值得在临床上合理推广应用。

Clinical effect of sutureless small Incision extracapsular cataract surgery extraction in the treatment of sclerotic nucleus cataract

Objective To observe the clinical effect of sutureless small incision extracapsular cataract extraction in the treatment of sclerotic nucleus cataract and summarize its value of clinical application.Methods Selected 433 eyes of 268 patients with the cataract treated in the Department of Ophthalmology of Hanzhong Central Hospital from June 2007 to June 2009.They all received the sutureless small incision extracapsular cataract extraction.It applied tobramycin eye drops on diseased eyes of all patients before the operation,and applied compound tobramycin eye drops after the operation.Observed and analyzed the clinical effect and took the statistical analysis.Results There were 397 eyes(91.7%) with the spherical corrected vision or naked vision ≥0.5 1 day after the operation,411 eyes(94.9%) with the one ≥0.5 1 week after the operation,and 409 eyes(94.5%) with the one ≥0.5 1 month after the operation,generally reaching to the stable level.There was no statistically significant difference in the spherical corrected vision or naked vision 1 day,1 week,1 month and 3 months after the operation(P>0.05);where was the statistically significant difference in the comparison of degree of corneal astigmatism between ones 1 day,1 week,1 month and 3 months after the operation and the one before the operation(P<0.05).There were 22 eyes(5.1%) had posterior capsular rupture during the operation,27 eyes(6.2%) had zonular dialysis(6.2%),with the incidence of complications during the operation of 11.3%.There were 94 eyes with the complications after the operation,with the incidence of 21.7%.Conclusion There are significant clinical effects of sutureless small incision extracapsular cataract extraction in the treatment of sclerotic nucleus cataract,which can significantly improve the spherical corrected vision or naked vision and reduce the occurrence of complications.It is safe and reliable and worthy to be reasonably popularized and applied in clinical practice.
