目的 探讨自动电脑验光仪验光结果的准确性。方法 应用 NIDEK AR— 82 0型电脑验光仪对 10 6例 2 10眼分成两个对照组进行睫状肌麻痹后电脑验光与视网膜检影、睫状肌麻痹前后电脑验光的对照分析。结果 睫状肌麻痹后电脑验光与视网膜检影的符合率分别为 r=0 .9897(球镜值 )和 r=0 .86 5 3(柱镜值 ) ,呈正相关。柱镜轴差异与柱镜值大小成反比 ,柱镜值≥ 0 .75 D以上差异均值 x =6 .0 0。睫状肌麻痹前后电脑验光的符合率分别为 r=0 .8874(球镜值 )和 r=0 .90 2 6 (柱镜值 ) ,x =7.0 3(柱镜轴差数 )。结论 调节麻痹后电脑验光可作为配镜的依据 ;调节存在时电脑验光球镜值作为配镜的参考依据 ,而散光部分可作为配镜的依据。
Objective To investigate the accuracy of automatic computer optometry optometry results. Methods NIDEK AR-82 0 computer refractor was used to divide 10 6 eyes 2 10 eyes into two control groups. Computerized optometry and retinal examination after cycloplegia were performed, and computerized optometry was performed before and after cycloplegia. Results The coincidence rates of computer optometry and retinoscopy after cycloplegia were respectively r = 0.9897 (spherical value) and r = 0.86 5 (lenticular value), which were positively correlated. The cylinder axis difference is inversely proportional to the cylinder size, and the cylinder mean is greater than or equal to 0 .75D x = 6 .0 0. The coincidence rates of computer optometry before and after cycloplegia were r = 0.8874 (spherical value) and r = 0.9026 (cylinder value), x = 7.03 (cylinder axis difference). Conclusions After adjusting paralysis, computer optometry can be used as the basis of optician adjustment. When adjusting, the value of computerized optometry sphere as the reference of optician, and astigmatism can be used as the basis of optician.
