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:目的分析角膜塑形镜试戴患者的基本情况及相关屈光参数,以期提高试戴成功率,并分析试戴失败原因。方法回顾分析45例(89只眼)进行角膜塑形镜试戴近视眼患者的资料。结果45例患者中,41例(91.1%)试戴成功,其中37例(82.2%)定制了镜片;4例(8.9%)试戴失败。通过对达到良好适配时的K值与平坦K值比较,得出角膜越平坦,两者的差值越小;而角膜越陡峭,两者的差值越大。4例试戴失败病例中,3例E值较试戴成功者E值明显偏低(P〈0.01),1例存在逆规散光。结论严格掌握好角膜塑形镜试戴者人选标准、规范验配流程,才能提高角膜塑形镜试戴成功率。对于E值偏低及存在逆规散光的患者试戴须谨慎。(中国眼耳鼻喉科杂志,2010,10:221.223)
简介:目的分析原发性眼眶肿瘤的组织来源、手术进路及手术效果。方法回顾性分析5年开眶手术治疗的眼眶肿瘤101例。结果前十位的眼眶肿瘤分别是:海绵状血管瘤22例(21.78%),静脉性血管瘤10例(9.9%),(表)皮样囊肿泪腺10例(9.9%),泪腺混合瘤8例(7.92%),炎性假瘤7例(6.93%),脑膜瘤6例(5.94%),腺样囊性癌5例(4.95%),淋巴瘤4例(3.96%),肉瘤3例(2.97%),神经鞘瘤2例(1.98%)。手术方法包括前路入眶68例,外侧开眶27例,眶内容6例,术后复发4例。结论开眶手术的术式选择与肿瘤的性质、位置、粘连情况、病变范围密切相关。术前对肿瘤的性质、位置、粘连程度的正确判断和手术操作技巧可减少术后复发等并发症。术后复发病例主要为脑膜瘤及泪腺肿瘤。
