简介:目的:评价翼状胬肉切除联合角膜缘干细胞移植术中,结膜植片两种缝合方法临床效果的差异。方法:采用前瞻随机对照试验,将48例48眼初发翼状胬肉患者随机分为A,B两组,每组24例24眼,A组术中结膜植片采用连续锁边缝合法;B组术中结膜植片采用间断缝合法。术中记录结膜缝合时间,术后随访6mo,记录拆线所用时间及眼部刺激评分情况。结果:术中平均植片缝合时间A组为14.05±2.30min,B组为19.34±2.12min,两组差异有统计学(P〈0.01)。眼部刺激情况分值在术后第3d(1.32±0.60vs1.68±0.35)和第5d(0.87±0.24vs1.26±0.68),A组得分均明显低于B组(P均〈0.05)。A组拆线所用时间为9.15±3.36min,B组拆线所用时间为12.61±3.89min,两组差异有统计学意义(P〈0.01)。结论:连续锁边缝合法提高了手术效率,减轻了术后的刺激症状,是一种安全高效的结膜植片缝合方法。
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。
