对人工晶体植入术后视功能,过去常用100%对比视标,以表示最小分离域值的形态觉机能。随着手术的进步,患者对手术的期望也不断增高,因此,术后应以综合性的视功能的质量(quality of vision)进行评价。动体视力(dynamic visual acuity,DVA或kinetic visual acuity,KVA)是一种与过去静态视力(static vision)明显不同的概念,在日常生活中,观察车子运动等动态物体的动体视功能是最重要的形态觉之一。动体视力分为两种类型:左右运动物体和迎面直线运动物
The visual function after intraocular lens implantation, the past often used 100% contrast target, to express the minimum separation of the value of the morphological function. As surgery progresses, the patient’s expectations for surgery continue to increase, and postoperative evaluation should be based on a comprehensive quality of vision. Dynamic visual acuity (DVA) or Kinetic visual acuity (KVA) is a concept that is obviously different from the past static vision. In daily life, dynamic visual acuity of dynamic objects such as car movement is the most important One of the important morphological perceptions. Dynamic visual acuity is divided into two types: about moving objects and on-line straight objects
