方法：对173例学龄前儿童进行检影验光，首先行HAR-800手持验光仪检查(试验组)，然后应用阿托品眼膏进行扩瞳检影验光(对照组)，比较两种检影验光的屈光差异。

结果：试验组球镜为1.59±0.61D，对照组为3.15±0.72D，两者有显著统计学差异(t=-82.89， P<0.01)，且具有相关性(r=0.87，P<0.01)。试验组散光为-0.62±0.51D，对照组为-0.48±0.55D，两者有显著统计学差异(t=-6.97，P<0.01)，且具有显著相关性(r=0.76，P<0.01)。

结论：HAR-800手持验光仪不能替代阿托品检影验光，但其结果可以反映学龄前儿童的屈光状况。

METHODS:Totally 173 preschool children were included in this study. They were performed HAR-800 hand-held autorefractor examination before using atropine ointments for cycloplegic refraction. The results from HAR-800 refractor were set as experimental group, and the cycloplegic refraction were controlled group. The refractions between the two groups were compared and analyzed.

RESULTS: The sphere was 1.59±0.61D in the experimental group, while 3.15±0.72D in the controlled group. The difference was significant(t=-82.89, P<0.001), however, there was a significant correlation(r=0.87, P<0.001, Pearsons correlation analysis). The cylinder difference was also significant(t=-6.97,P<0.001)and a significant correlation also existed between the two groups(r=0.76,P<0.001, Pearsons correlation analysis).

CONCLUSION: The HAR-800 hand-held autorefractor can not replace cyclopegic refraction using atropine, but the results can reflect the preschool children refraction.
