目的 观察不同手术位置切口对非超声乳化白内障手术角膜散光的影响,以期为非超声乳化白内障手术的临床推广提供参考.方法 回顾性分析接受小切口白内障非超声乳化吸除人工晶状体植入术患者资料,共120眼.根据患者手术位置切口不同分为观察组和对照组,每组60眼.术中观察组选择上方角膜缘切口,对照组均选择上方角膜缘切口.对2组术前后角膜散光度及者手术前后裸眼视力>0.5眼数情况进行比较.结果 2组患者术前、术后3 d的角膜散光度比较差异无统计学意义(P>0.05);但随着时间推移,患者角膜散光度逐渐升高,3个月达到最高值后略有降低(P<0.01);2组患者手术前、术后3 d及术后1周裸眼视力>0.5眼数比较差异无统计学意义(P>0.05);观察组术后3个月裸眼视力>0.5眼数高于对照组(P<0.01).结论 小切口白内障非超声乳化吸除人工晶状体植入术在角膜曲率最大子午线行切口处操作,可有效提高患者治疗效果,术后安全性高,值得临床推广应用.
目的:探讨用不同的手术方式治疗白内障的临床效果.方法:将2016年7月至2017年8月期间保定新视眼科医院收治的98例白内障患者(106只患眼)作为研究对象.将这98例患者平均分为对照组和观察组.对对照组患者进行白内障囊外摘除术,对观察组患者进行超声乳化白内障吸除术.然后,比较两组患者眼压的水平、视力恢复良好的比率及其术后并发症的发生率.结果:经过治疗,与对照组患者相比,观察组患者眼压的水平和术后并发症的发生率均更低,其视力恢复良好的比率更高(P<0.05).结论:与进行白内障囊外摘除术的效果相比,对白内障患者进行超声乳化白内障吸除术的效果更好,可明显降低其眼压,提高其视力,且安全性高.
To investigate the advantage of using the medical sodium hyaluronate gel undergo goniosynechialysis, and to compare the difference of the viscoelastic agent and perfusion fluid by clinical control study. ●METHODS:Totally 103 cases (103 eyes) patients who had angle- closure glaucoma (ACG) with cataract all in Beijing Tongren Hospital affiliated to Capital Medical University, from September 2012 to February 2013. All the patients had primary glaucoma or recurrence ACG with cataract. Their intraocular pressure (lOP) could be controlled in normal value using one or two anti -glaucoma medications. We divided all the patients into two groups by chance. Experimental group had 53 cases (50 eyes), and control group had 50 cases (53 eyes). Two groups all had been performed phacoemulsification combined with goniosynechialysis by the same experiential operator. But experimental group did goniosynechialysis using the medical sodium hyaluronate gel, control group did goniosynechialysis using perfusion fluid. We observed the change of lOP, central anterior chamber depth and anterior chamber structure of two groups in postoperative 1mo. ●RESULTS: SPSS19. 0 statistics software was utilized to analyze the data, This study selected one- side test α =0. 05, adopted paired t - test or two- sample t - test. We obtained that experimental group lOP decreased 12. 42 ± 0. 04mmHg, anterior chamber depth increased 1. 276 ± 0. 201mm; that control group lOP decreased 6. 56 ± 0. 08mmHg, anterior chamber depth increased 0. 852 ± 0. 132mm. And experimental group anterior chamber angle opened more widely than the other group, the comparison had statistical significance (P<0. 05). ●CONCLUSlON: ln phacoemulsification combine with goniosynechialysis,use medical sodium hyaluronate gel do goniosynechialysis can more effectively decrease lOP. This because the medical sodium hyaluronate gel has high glutinousness, it can separate angle of anterior chamber and controlling lOP effectively.
