摘要目的 研究配戴不同设计眼镜片对近视眼AC/A值的影响.方法 收集2010年9月至2011年2月来验光的近视患者172例(344只眼),年龄12～18岁,平均(15.37±2.01)岁,屈光度-1.00～-6.00 D,平均(-3.50± 1.42)D,配戴时间1年.分为两组:非球面镜组,104例(208只眼)；多焦点镜组,68例(136只眼).计算非球面镜组和多焦点镜组AC/A值,并将结果进行分析.所有资料以均数±标准差((x)±s)表示,采用独立样本t检验进行分析.结果 配戴非球面镜组AC/A值为3.52±1.67,多焦点镜组的AC/A值为2.88±1.23,多焦点镜组小于非球面镜组,两组间差别有统计学意义(t =2.71,P＜0.05).结论 近视患者持续戴多焦点眼镜对AC/A值的影响大于戴非球面眼镜者,并能使AC/A值一定程度减弱,集合功能减弱.

abstractsObjective To investigate myopia AC/A ratio following the different designed glasses.Methods A prospective study.A total of 172 (344 eyes) myopia patients who underwent refraction examination from September 2010 to February 2011 were collected in our research,including 12 to 18 years old,average (15.37±2.01) years old,and-1.00 diopter to-6.00 diopters,mean (-3.50 ±1.42) D.All patients wore glasses for 1 year.All study subjects were divided into two groups:non-spherical lens group,104 patients (208 eyes),and 68 patients (126 eyes),AC/A ratio of non-spherical lens group and multifocal lens group was measured.And the results were analyzed.All data were mean ± standard deviation ((x)±s) said,using Independent-Samples T-test analysis.Results AC/A value of non-spherical lens group were 3.52±1.67.AC/A value of multifocal lens group were 2.88±1.23.Multifocal lens group was less than the non-spherical lens group.The differences between two groups were statistically significant (t =2.71,P ＜0.05).Conclusions The impact of myopia AC/A ratio who continue to wear multi-focal glasses is greater than that of non-spherical glasses,and makes the AC/A ratio decrease to some extent.
