目的:探讨屈光不正的发病规律及矫正视力效果。方法:对1690例3277眼屈光不正进行统计分析。结果:近视多于远视,单纯近视多于单纯近视散光及复性近视散光;单纯远视散光及复性远视散光多于单纯远视;混合散光较少。本组病例大部分是学生,占患病人数的79.47%。屈光度<=3.00的,84.21%可矫正视力达到5.0。结论:近视多于远视,学生患病占大部份;屈光不正度数越低,矫正视力越好。 Objective: To investigate the incidence of refractive errors and correct visual acuity. Methods: A total of 1690 cases of 3277 refractive errors were statistically analyzed. Results: Myopia more than hyperopia, simple myopia more than simple myopic astigmatism and refraction myopic astigmatism; simple hyperopia astigmatism and hyperopia astigmatism refraction more than simple hyperopia; mixed astigmatism less. The majority of cases in this group of students, accounting for 79.47% of the number of patients. Refractive degree <= 3.00, 84.21% can correct visual acuity reached 5.0. Conclusion: Myopia is more than hyperopia, the majority of the students’ illness; the lower the degree of refractive error, the better corrected visual acuity.
