简介：对有晶状体眼植入后房型人工晶状体是矫正屈光不正的有效方法，植入的后房型人工晶状体目前主要有可植入式接触镜（implantablecontactlens，ICL）和有晶状体眼屈光性晶状体（phakicrefractivelens，PRL）。对术后患者主观视觉质量（视力、对比敏感度）、客观视觉质量（波前像差、点扩散函数、斯特尔比率及光学传递函数）的研究显示，主观视力的提高也伴随着客观视觉质量的改善，但部分患者术后出现光晕及眩光症状。本文主要对ICL和PRL植入术后主观及客观视觉质量的临床研究做一综述，对可影响视觉质量的术后并发症如晶状体前囊膜下混浊、青光眼及角膜内皮功能异常等需进一步远期随访。

简介：Toric有晶状体眼后房型人工晶状体（TICL）是一种以亲水性胶原共聚物为材料的人工晶状体,可用来矫正近视＜-20.00DS、远视＜＋10.00DS合并散光1.00～6.00DC的屈光不正.现今临床上TICL植入术不仅用于矫正屈光不正合并高度散光,而且开始应用于因圆锥角膜、角膜移植术等引起的继发性高度角膜散光的矫正.本文就TICL目前在临床上的应用及其设计选择方面的进展进行综述,着重探讨TICL植入术在特殊应用中的安全性、有效性、稳定性.
