  • 简介:目的:探讨超声乳化术治疗特殊类型白内障的安全性和有效性。方法:回顾性分析临床资料,研究超声乳化吸出(联合)人工晶状体植入术治疗青光眼术后白内障、小瞳孔白内障、葡萄膜炎并发白内障和外伤后并发白内障等特殊类型白内障的技术要领。结果:进行治疗的73例84眼特殊类型白内障患者中,单纯行超声乳化术27例28眼,植入后房型人工晶状体52眼,植入前房型人工晶状体4眼;术后1mo平均眼压12.72±2.63mmHg,脱盲率99%,脱残率96%;并发症发生率4%。结论:特殊类型白内障手术难度大,超声乳化术切口小,可保留晶状体后囊膜和植入人工晶状体,是摘除特殊类型白内障的理想术式。

  • 简介:目的分析Nd:YAG激光行后囊膜切开术治疗白内障复明手术后不同类型后发性白内障的治疗作用与术后并发症。方法对白内障复明手术后,109例(109眼)后发性白内障依据后囊昆浊形态分为:A组Elschnig珍珠样小体型46例(46眼),B组纤维化型63例(63眼)。采用十字形切开法或开罐式切开法进行激光后囊膜切开术,比较两组激光术前最佳矫正视力与激光术后最佳矫正视力以及激光术后并发症情况。结果A、B两组内激光术后最佳矫正视力较激光术前最佳矫正视力改善(P〈0.05);A组术后眼压升高和房水闪辉明显高于B组(P〈0.05)。结论Nd:YAG激光是治疗白内障复明手术后不同类型后发障的常用有效的治疗方法,激光术后并发症与后发性白内障类型有关。

  • 简介:目的:分析EX-PRESS引流联合生物羊膜植入术治疗原发性开角型青光眼(primaryopenangleglaucoma,POAG)的有效性及安全性。方法:回顾性分析2015-01/2017-02在我院接受EXPRESS引流(P50)+羊膜植入术(31例38眼,试验组)与单纯EX-PRESS引流(P50)植入术(22例34眼,对照组)患者的临床资料,统计分析两组术前,术后1d,1wk,3、6mo眼压变化、滤过泡情况以及并发症发生率。结果:术后各个时间点上,试验组及对照组的平均眼压均较术前明显下降,其差异有统计学意义(P<0.05),术后1d,1wk,试验组与对照组平均眼压差异无统计学意义(P>0.05),在术后3、6mo,对照组眼压较试验组眼压高,其差异有统计学意义(P<0.05)。在术后3mo,试验组中功能性滤过泡比例较对照组高,其差异有统计学意义(P<0.05),试验组和对照组术后并发症主要包括浅前房、出血、虹膜后粘连、角膜水肿,两组中其发生率差异无统计学意义(P>0.05)。结论:EX-PRESS引流植入术联合生物羊膜植入可以安全有效降低眼压,改善术后滤过泡情况,并有远期降低眼压的作用。
