Analysis of visual acuity before and after refraction in people over 50 in ophthalmic outpatients
AIM: To investigate the visual acuity of people over 50 years in ophthalmic clinic and visual impairment before and after refractive correction.<p>METHODS: Totally 149 cases(298 eyes)of refractive error were examined and corrected using autorefractor and retinal optometry. The information of a...

The mean visual acuity was 0.42±0.21 and 0.63±0.32 respectively before and after correction. Corrected visual impairment was in 186 eyes(65.3%).
