摘　　要：眼科光学生物测量仪是一种用于测量人体眼球参数的仪器,被广泛应用于眼科的临床检查中,其测量人体眼球参数是用于屈光手术检查、近视档案建立、青光眼、白内障等临床诊断和手术的重要依据,因此其测量量值的准确与否至关重要。文中选用眼轴标准模拟眼和角膜曲率用计量标准器对光学生物测量仪的眼轴长度和角膜曲率半径进行测量校准,并对其测量结果的不确定度评定方法进行研究分析。Optical bio-measuring instrument is a kind of instrument used to measure human eyeball parameters,which is widely used in ophthalmic clinical examination,the measurement of human eye parameters is an important basis for the clinical diagnosis and surgery of refractive surgery,Myopia,Glaucoma,cataract and so on.In this paper,the eye axis length and corneal curvature were measured and calibrated with a standard measuring instrument,and the evaluation method of the uncertainty of the measurement result was studied.
