ABSTRACT
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 ). 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.
