简介:目的:探讨人工晶状体眼老视的科学检测方法。方法:随机抽取年龄在40~75岁之间“白内障超声乳化+人工晶状体植入”术后老视患者80例(118眼)从术后1wk开始随访6mo以上,检测角膜散光度数变化,并根据患者的阅读需要和距离进行客观和主观验光。结果:白内障术后角膜散光1wk~1mo的平均度数与术前比较差异有显著性(P〈0.01),3mo的角膜散光与术前比较差异无显著性,白内障人工晶状体眼的老视近附加3个年龄组间比较差异无统计学意义。结论:白内障术后人工晶状体眼的近附加验配不随年龄的增加而增加,应待角膜散光稳定后根据被测的调节参数进行精确的验配,而不能简单地按照经验公式开出处方。

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。
