目的：比较Medcall镜架与常规镜架配戴前后的变形移位程度，探讨眼镜配戴变形移位定量测定的可行性。方法选取2013年3～8月复旦大学附属金山医院眼科门诊验光配戴框架眼镜的6～17岁儿童及青少年共95例（ Medcall镜架35例、常规镜架60例），借助自制的镜架配戴变形移位测定器，对所有镜架予数码照相记录，数据导入Auto-CAD软件，量化分析镜架外张角（双侧镜腿夹角之和）及镜腿间距离。1个月后对随访到的29例儿童及青少年（ Medcall镜架14例、常规镜架15例）再次进行上述测量，比较儿童配戴不同类型眼镜前后眼镜的变形移位度。结果配戴前14例Medcall眼镜及15例常规镜架的平均镜架外张角分别为（＋3．89±4．58）°及（＋0．97±5．76）°，2组间差异无统计学意义（t＝1．50，P＝0．14）。平均镜腿距离分别为（135．1±6．7）mm及（130．4±13．9）mm，差异无统计学意义（t＝1．14，P＝0．27）。配镜1个月后，2组镜架外张角分别为（＋4．69±4．57）°及（＋8．49±5．14）°，2组间差异有统计学意义（t＝2．09，P＝0．04）。镜腿间距离分别为（136．1±6．7）mm及（145．3±7．4）mm，差异有统计学意义（t＝3．51，P＜0．05）。14例Medcall镜架初配及配戴1个月后，两者间镜架外张角及镜腿间距离差异均有统计学意义（配对t＝4．49， P＜0．05；t＝2．79，P＜0．05）；15例常规眼镜初配及配戴1个月后，两者间镜架外张角及镜腿间距离差异均有统计意义（ t＝9．83， P＜0．05；t＝5．41， P＜0．05）。结论眼镜架随配戴时间延长会出现变形移位，Medcall镜架与常规镜架相比配戴后变形移位更小，本测量方法可以客观观察到眼镜的变形移位情况。（中国眼耳鼻喉科杂志，2014，14：305-308）

Objective To investigate the feasibility of quantitative measurement on the deformation degree of spectacles frames of Medcall and routine spectacles frames before and after wearing .Methods Ninety-five children (aged from 6 to 17 years) with glasses were chosen (35 Medcall spectacles and 60 routine spectacles) from March 2013 to August 2013.Spectacles deformation measuring equipment was used to record the deformation .Auto-CAD software was used to analyze the spectacles frame open angles and distance .One month later , the same measurement was performed in the 29 follow-up children ( 14 Medcall spectacles and 15 routine spectacles ) .Results Before wearing , the average spectacles frame open angles of 14 Medcall spectacles and 15 routine spectacles were (+3.89 ±4.58)°and (+0.97 ± 5.76)°(t=1.50,P=0.14);the average spectacles frame distances were (135.1 ±6.7) mm and (130.4 ±13.9) mm (t=1.14,P =0.27).There were no significant differences in spectacles frame open angles and spectacles frame distances between two groups .One month later , the average spectacles frame open angles of 14 Medcall spectacles and 15 routine spectacles were (+4.69 ±4.57)°and ( +8.49 ±5.14)°respectively (t =2.09,P=0.04).The average spectacles frame distances were (136.1 ±6.7) mm and (145.3 ±7.4) mm(t=3.51,P<0.05).There were significant differences in spectacles frame open angles and spectacles frame distances between the two groups .Meanwhile , there were significant differences in spectacles frame open angles (t=4.49, P<0.05) and spectacles frame distances (t=2.79,P<0.05 ) before and after wearing Medcall spectacles at one month .There were significant differences in spectacles frame open angles (t=9.83, P<0.05) and spectacles frame distances (t=5.42, P<0.05) before and after wearing routine spectacles at one month .Conclusions The spectacles frame will deform after wearing .Comparing to the routine spectacles , Medcall spectacles are less likely to deform .The method could be used to observe the deformation of spectacles objectively.
