目的：了解本院眼科门诊50岁以上部分人群屈光状态及视力矫正前后状况，探讨视力损害的相关影响因素。
方法：选取该组人群149例298眼，使用电脑验光联合视网膜检影进行屈光矫正，并以问卷方式了解患者年龄、文化水平、经济状况及居住地。
结果：该组人群149例298眼中，屈光不正281眼(98.6%)。其中近视性屈光不正有119眼(42.3%)，远视性屈光不正有94眼(33.5%)，混合性散光有68眼(24.2%)。验光矫正前后平均视力分别为0.42±0.21和0.63±0.32，可矫正的视力损害为186眼(65.3%)。低教育程度、低收入、居住在农村是视力损害的危险因素。
结论：未矫正的屈光不正是视力损害的重要因素，通过矫正可使大部分人脱离视力损害的范围。应加强老年人群特别是贫困地区、低教育程度及低收入人群的视力保健和相关知识的普及。

[Abstract]
AIM: To investigate the visual acuity of people over 50 years in ophthalmic clinic and visual impairment before and after refractive correction.
METHODS: Totally 149 cases(298 eyes)of refractive error were examined and corrected using autorefractor and retinal optometry. The information of age, sex, economy, income and living standard were collected by questionnaire.
RESULTS: Out of 149 cases(298 eyes), 281 eyes(98.6%)had refractive error. 119 eyes(42.3%)had myopia, 94 eyes(33.5%)had hyperopia and 68 eyes(24.2%)had mixed astigmatism. 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%). Old age, low education, low income and rural area were risk factors for visual impairment.
CONCLUSION: Uncorrected refractive error is an important cause of visual impairment in elderly people. It can be promoted by refractive correction, which may benefit for their living quality.
