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:目的探讨可调节缝线技术应用于小梁切除术的临床疗效。方法对92例(107只眼)原发性闭角型青光眼,随机分为两组;观察组(A组)48例56只眼行可调节缝线小梁切除术;对照组(B组)44例51只眼行传统小梁切除术。观察比较术后前房、眼压、住院日等情况。结果术后一周内浅前房的发生率观察组为16.1%(9只眼),对照组为31.4%(16只眼);术后半年,眼压的控制两组无明显差异(P〉0.05);平均住院日观察组小于对照组,差异有显著性(P〈0.05)。结论小梁切除术联合应用可调节缝线技术,可减少术后早期浅前房的发生,增加手术安全性,缩短平均住院日,但对眼压的长期控制并不优于传统的小梁切除术。
简介:目的通过观察使用和不使用白星技术行超声乳化白内障吸出术后的效果,探讨白星超声乳化技术的优点.方法随机选取40例硬核(Ⅲ~Ⅳ级)白内障患者共47眼,随机分为A、B两组行超声乳化白内障吸出并人工晶状体植入术,A组使用白星技术,B组使用普通的超声乳化技术.对比两组手术后视力恢复情况、角膜水肿情况、超声乳化能量及每组手术前后角膜内皮计数减少量.结果A组与B组术后恢复较好视力(≥0.7)的比例差异无显著性,A组术后第一天的角膜水肿情况明显好于B组,手术前后角膜内皮细胞丢失数量明显少于B组,所用超声乳化的平均能量明显低于B组.结论白星技术所用能量少,术后反应小,组织损伤小,恢复快,值得临床推广应用.
简介:目的评价甲基纤维素联合透明质酸钠制作软壳技术在白内障小切口非超声乳化手术中的效果.方法白内障“复明工程”患者261例295眼.随机分为A、B两组,其中A组术中单用透明质酸钠,B组术中联合使用甲基纤维素和透明质酸钠.手术方法为小切口非超声乳化加人工晶体植入.结果术后第ld裸眼视力大于0.3者,A组78.79%(104/132),B组87.1%(142/163),两组之间差异显著(P<0.05);术后第7d视力在0.3以上者,A组93.9%(124/132),B组94.5%(154/163).两组间差异无统计学意义(P>0.05).术后角膜水肿情况:术后第1天,A组17.42%(23/132),B组9.8%(16/163),两组间比较差异有统计学意义(P<0.05).术后第7天,A组2.27%(3/132),B组2.45%(4/163),两组间比较差异无统计学意义(P>0.05).结论甲基纤维素联合透明质酸钠制作软壳技术比单用透明质酸钠更安全.
