关注眼内散射光对人工晶状体眼视觉质量的影响

Attention to the effect of intraocular straylight in pseudophakic eyes on visual quality

随着人们生活水平的提高，白内障患者对术后视功能的期望越来越高，不仅要有良好的视力，而且要求满意的视觉质量。人工晶状体（IOL）眼散射光的大小成为评价患者术后视觉质量的重要参数，患者术后一系列异常闪光感现象的出现均与其相关。IOL植入术后，引起IOL眼散射光增大的因素主要包括IOL的材质、IOL边缘设计、手术操作及后发性白内障（PCO）和瞳孔直径的影响。围绕关注眼内散射光对IOL眼视觉质量的影响，从而提高手术质量和患者的视觉质量这一主题，从眼内散射的作用机制、影响因素等方面进行阐述。

As ophthalmic science develops,the expectations of the patients undergoing cataract also advance. Good Snellen visual acuity is not always an indicator for patient＇s satisfaction, and the visual quality is much more important. The intraocular straylight is one of the important parameters to analyze the vision quality after surgery. The pseudophakic photic phenomena, such as dysphotopsia, is closely related to the intraocular straylight. The posterior capsular opacification,the material and the edge design of the intraocular lens （IOL） , the diameter of IOL optical component are the important influential factors that cause the dysphotopsia. Great attention must be paid to it,which make us to understand the straylight deeply in order to improve postoperative visual quality.
