摘　　要：目的评价国产 YZ54 A 型眼科超声诊断仪在白内障术前眼轴测量中的准确性和安全性。方随机检测白内障患者84例(84眼),分别用 NIDEK US-1800型眼科超声诊断仪(进口 A 超组)和 YZ54 A 型眼科声诊断仪(国产 A 超组)行眼轴测量。结果 84例(84眼)白内障患者眼轴测量均顺利完成,无并发症发生。据测得眼轴长度分为3组:短眼轴组(眼轴<23mm)共23眼、正常眼轴组(眼轴≥23mm 和≤25mm)共27眼长眼轴组(眼轴>25mm)共34眼。各组中进口 A 超组眼轴长度、中央前房深度、晶状体厚度、玻璃体腔长度国产 A 超组相比差异均无统计学意义(P>0.05)。结论 YZ54 A 型眼科超声诊断仪眼轴测量的准确性和安性达到进口 A 超组产品的性能水平,能满足临床测量要求。(中国眼耳鼻喉科杂志,2007,7:39～40)Purpose To evaluate the accuracy and safety of YZ54 A Scan in axial length measurement of preoperative cataract surgery. Methods The axial lengths of 84 eyes（84 cases） were measured with both NIDEK US-1800 A Scan（NIDEK A Scan group） and YZ54 A Scan （YZ54 A Scan group）. Results The axial lengths of all the eyes were measured successfully without any comphcations. Based on the axial lengths measured, 84 eyes were divided into three groups：short axial length group（ axial length was less than 23 mm;23 eyes） ,normal axial length group （axial length was equal to or more than 23 mm and equal to or less than 25 mm; 27 eyes） and long axial length group （ axial length was more than 25 mm; 34 eyes）.There were no statistically significant differences in axial length, the depth of central anterior chamber, the depth of lens and the length of vitreous cavity between NIDEK A Scan group and YZ54 A Scan group. Conclusion The accuracy and safety of YZ54 A Scan in axial length measurement of pre-operative cataract surgery are encouragble which are as the same as that of NIDEK US-1800 A Scan. This kind of Scan meets the chnical acquirement. （Chin J Ophthalmol and Otorhinolaryngol, 2007,7 ： 39-40 ）
