目的:比较手持电脑验光仪与带状光检影仪在招飞屈光检查中屈光值测量的差异,探讨手持电脑验光仪在招飞体检中应用的可行性。
方法:对进入屈光检查的招飞学生317名634眼散瞳后,分别用手持电脑验光仪和带状光检影仪进行验光检查。对主要指标(球镜度数、柱镜度数及轴向)的屈光值进行差异性检验和相关性分析,并对淘汰率进行比较分析。
结果:手持电脑验光仪球镜和柱镜屈光度值较视网膜检影结果偏负,其差异有统计学意义(P<0.05),但具有统计学相关性(r=0.733,0.694),两者轴位的检验结果差异无统计学意义(P>0.05)。手持验光仪淘汰率较检影高,存在有误淘现象。
结论:手持电脑验光仪与检影测量结果有较好的一致性,在招飞屈光检查中有应用的价值。

AIM:To compare the difference between diopter of refration measured after cycloplegic mydriasis with retinoscopy and hand-held autorefractor so as to explore the feasibility of using hand-held autorefractor for refraction screening in cadet candidates.
METHODS:Respectively using hand-held autorefractor and streak retinoscope to do optometry examination in 317 cadet candidates students(634 eyes)after mydriasis. Main index of refraction values(spherical, cylindrical mirror degree and axial)were analyzed by difference test and correlation analysis. And the elimination rate was comparatively analyzed.
RESULTS:Diopters of sphere and cyclic refraction measured by hand-held autorefration were significantly higher than those by retinoscopy(P<0.05), but the correction analysis showed that there was high correlation(r=0.733, 0.694), axial of refration measured by these two methods were non-significant(P>0.05). The disqualifying rate using autorefraction was much higher than that using retinoscopy. It was easy to be wrongly eliminated.
CONCLUSION:Because of the high correlation between diopters of autorefraction measured by retinascopy and autorefractor, autorefraction has application value in refraction screening in cadet candidates with normal vision.
