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:青光眼房水引流装置植入术是目前临床上广为推崇的一种治疗难治性青光眼的有效方法.各引流装置在设计、材料、引流盘的面积和形状及有无阀门或限流器上存在差异.现就临床常用的青光眼房水引流装置的结构特点、作用机制、并发症、不足之处以及当前研究进展做一简要概述.
