有晶状体眼后房型人工晶状体植入术后的视觉质量

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(implantable contact lens，ICL)和有晶状体眼屈光性晶状体(phakic refractive lens，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。

Visual quality in posterior chamber phakic intraocular lens implantation

Posterior chamber intraocular lens implantation was effective for correcting refractive errors. More scientific studies about subjective visual quality(visual acuity, contrast sensitivity)and objective visual quality(wave front aberration, point spread function, Strehl ratio, modulmion transfer function)had showed that the improvement of subjective visual acuity was accompanied with the improvement of objective visual acuity after phakic intraocular lens implantation. However, the complications, such as anterior subcapsular cataract, glaucoma and decomposition of corneal endothelium needed to be long-term followed up. This article summarized the visual quality research after posterior chamber phakic intraocular lens implantation.
