目的：比较Lenstar 900与A型超声和角膜曲率计在白内障患者眼生物学测量中测量眼轴长度( AL )、前房深度( ACD)及角膜曲率( K1,K2,Km)上的差异,并分析其一致性,为Lenstar 900临床应用提供参考。<br> 方法：选取接受白内障手术的患者36例50眼,晶状体核均在Ⅳ级以下,术前分别采用Lenstar 900、A超和角膜曲率计完成AL,ACD和K1,K2,Km的测量,比较测量结果的差异采用配对t检验,测量结果的相关性采用 Pearson相关分析,测量结果的一致性采用Bland-Ahamn统计分析。<br> 结果：Lenstar 900与A型超声测量AL和ACD值之间的差异无统计学意义( P>0.05)。 Lenstar 900与角膜曲率计测量Kl,K2和 Km 值的差异均无统计学意义(P>0.05)。Lenstar 900与A型超声和角膜曲率计测量的所有参数均具有密切的线性相关(r>0.9,P<0.05),Bland-Ahamn统计分析一致性良好。<br> 结论：Lenstar 900与A型超声和角膜曲率计对白内障患者术前生物学测量结果准备可靠,可以相互替代,但是Lenstar 900不仅可以一次完成对AL、ACD和角膜曲率的测量,而且同时可以获得角膜厚度、晶状体厚度、角膜缘白到白距离、瞳孔大小、光轴的偏心率及视网膜厚度等参数,具有测量过程非接触、方便快捷、节约时间等优点,具有广泛的应用前景。

AIM:To investigate the differences among Lenstar 900, A-scan ultrasound and keratometer in measurement of axial length ( AL ) , anterior chamber depth ( ACD ) and corneal curvature ( K1 , K2 , Km ) , and evaluate the consistency of the instruments, with the purpose providing references for the clinical application of Lenstar 900. <br> METHODS: In this study we picked up 36 patients ( 50 eyes ) underwent cataract surgery, and lens nucleus hardness were under level IV. Before the operation, AL, ACD and K1 , K2 , Km were measured by Lenstar 900, A-scan ultrasound and keratometer respectively. The differences between the results were compared by the paired t-test. The correlation of the results was analyzed by Pearson correlation analysis, and the consistency was measured by Bland-Ahamn method. <br> RESULTS: The mean AL and ACD values measured by Lenstar 900 and A-scan ultrasound had no significantly statistic differences (P>0. 05). The K1, K2, Km measured by Lenstar 900 and keratometer were not significantly statistical different (P>0. 05). The results measured by these three instruments had close linearity correlation ( r>0.9, P<0. 01). The consistency of the results was well in Bland-Ahamn analysis. <br> CONCLUSION:The preoperatively biometric result of Lenstar 900, A - scan ultrasound and keratometer in patients with cataract are all reliable, and they can be substituted by each other. However, Lenstar 900 can not only measure AL, ACD and corneal curvature at the same time, but also cornal thickness, lens thickness, white to white, pupil size, optical axis eccentricity, retinal thickness and so on. It has a number of advantages such as non-touching, convenient and efficient, and can be recommended to use widely.
