摘　　要：以前的眩光测试仪大部分都是测量有眩光条件下的视力或对比敏感度,而且缺乏一种被广泛接受的标准。而C-Quant散射光计量仪是以“补偿比较”的方法为基础,精确客观地直接定量患者眼内散射光,操作简单迅速,可广泛用于视功能检查,尤其是早期白内障的检测、各种人工晶状体性能的评估、人工晶状体植入术预后的评价及屈光矫正手术的疗效评估。Over the years,several glare testers,to measure the degree and intensity of glare,have been developed.Most of these measure either the visual acuity or contrast sensitivity in the presence of a glare source.However,none of these have evolved into a universally accepted standard for glare testing.C-Quant(Oculus company,Germany)enables a direct measure of intraocular stray light using the"Compensation Comparison"method,which is relatively simple to operate and can be extensively used to promptly assess visual function,particularly for the measurement of early cataract,evaluation of the functions of various intraocular lenses,prognosis of intraocular lens implantation,and therapeutic effect of refractive surgery.
