摘　　要：目的探讨电脑验光仪对儿童验光的准确性和实用价值,了解电脑验光仪能否在儿童中应用。方法对257例屈光不正儿童先予TOPCON-7100电脑验光初测,再用1%阿托品眼水1日2次,连用3d,然后分别进行电脑验光与检影验光。结果散瞳前电脑验光与检影验光球镜均值比较有较大差异(P<0.05);散瞳后电脑验光与检影验光球镜均值、柱镜值均值比较有高度相关性(r=0.971,r=0.801),差异无显著性(P>0.05);电脑验光与检影验光柱镜轴差异较大(P<0.05)。结论电脑验光仪尚不能取代检影验光,可作为快速检查辅助工具。Objective:To study the precision and practical value of computer optometry instrument for children' s optometry,finding out whether the computer optometry instrument can be used for children or not.Method:Pre-liminary test by TOPCON-7100computer optometry was made on257children with abnormal phototropism,and then1%of Atopin liquid medicine was dropped to eyes twice a day for three days in succession.After that,comput-er optometry and retinoscopy optometry were made separately.Result:Before pupil scatter,there was much differ-ence in the average value from lens between computer optometry and retinoscopy optometry.(P<0.05);after pupil scatter,the average value from lens of computer optometry had close relativity to that of retinoscopy optometry and the average value from column lens(r=0.971,r=0.801).The difference was not significant(P>0.05).The difference in the column lens axis between computer optometry and retinoscopy optometry was quite big(P<0.05).Conclu-sion:computer optometry instrument cannot replace retinoscopy optometry,but can be used as instant secondary tool for medical examination.
