摘　　要：目的:应用"云夹"(杭州镜之镜公司)对不同年龄层、不同屈光状态患者进行习惯阅读距离测定。基于习惯阅读距离计算近附加值(ADD),与传统法ADD进行比较,评价"云夹"辅助老视验配方法的有效性。方法:横断面研究。共纳入2018年4月至2019年2月以爱尔眼视光研究所名义向社会招募的28~60岁矫正视力正常的受检者181例。受检者经框架眼镜矫正后,通过传统方法测试ADD,并利用"云夹"客观监测习惯阅读距离,进一步计算"云夹"法ADD。以年龄40岁为界,将受试者分为老视前组(<40岁)和老视组(≥40岁);以等效球镜-0.50 D为界,将受试者分为近视组(屈光度<-0.50 D)和正视组(屈光度为-0.50^+0.50 D),采用析因设计分析年龄及屈光度对习惯阅读距离的影响,应用配对t检验、相关性分析及Bland-Altman分析评价传统法ADD与"云夹"法ADD的一致性。结果:在所有受检者中,老视组习惯阅读距离大于老视前组[(0.37±0.06)m vs.(0.38±0.06)m,F=5.51,P=0.02],习惯阅读距离不受屈光状态影响(F=1.48,P=0.23);"云夹"法ADD与传统法ADD差异无统计学意义(t=-1.46,P=0.15),且呈现高度相关性(r=0.74,P<0.001),Bland-Altman分析显示,2种方法的平均偏差仅为-0.08 D。结论:习惯阅读距离受老视状态影响,"云夹"法ADD与传统法ADD具有较高的一致性,"云夹"辅助老视验配是一种客观、准确的个性化老视验配方法。Objective:To evaluate the validity of the presbyopic prescription based on Clouclip(Glasson Technology Co.,Ltd,Hangzhou,China).Methods:A total of 181 subjects aged 28-60 years old with normal BCVA were included in the cross-sectional study.Refractive errors were corrected using frame glasses.Clouclip was used to monitor the habitual reading distance of subjects and the near addition(ADD)was calculated with habitual reading distance.The ADD was tested by both the traditional method and Clouclip.The habitual reading distance was tested first,then the ADD of Clouclip was calculated based on habitual reading distance.Subjects were divided into a pre-presbyopia group(<40 years old)and a presbyopia group(≥40 years old)according to age.Subjects also were divided into a myopia group(<-0.50 D)and emmetropia group(-0.50-+0.50 D)based on refractive error.A factorial design ANOVA was used to analyze the influence of age and refractive error on habitual reading distance.A paired t-test,association analysis and Bland-Altman analysis were used to evaluate the consistency of traditional ADD and the ADD of Clouclip.Results:In all subjects,the presbyopic group had a farther reading distance than the pre-presbyopic group(0.37±0.06 m vs.0.38±0.06 m,F=5.51,P=0.02),and the habitual reading distance was not affected by refractive status(F=1.48,P=0.23).The ADD of Clouclip was highly correlated with the traditional ADD(r=0.74,P<0.001).The Bland-Altman analysis showed that the average deviation was only-0.08 D.Conclusions:The habitual reading distance is affected by presbyopic status.The ADD of Clouclip is highly consistent with the traditional ADD.The method of using Clouclip to calculate ADD is an objective,accurate and personalized method for presbyopic prescriptions.
