目的检验Lenstar LS900生物测量仪与AL-SCAN、Pentacam旋转Scheimpflg相机、超声生物显微镜(UBM)和Tomey EM-3000的生物测量结果是否具有可比性。在临床研究中，用Lenstar LS900和AL-SCAN测量眼轴(AL)和晶状体厚度(LT)，用Lenstar LS900、A-Scan、Pentacam和UBM测量前房深度(ACD)，用Lenstar LS900、Pentacam和Tomey EM-3000测量中央角膜厚度(CCT)。使用Wilcoxon-Mann-Whitney U检验和皮尔逊相关计算对结果进行比较。结果Lenstar与AL-SCAN的相关性最高(r=0.975；P<；0.001)。对于LT测量，这两种设备之间的相关性也很好(r=0.699；P<；0.001)。在ACD方面，Lenstar与椎弓根或UBM的相关性良好(r分别为0.948、0.704，P均为0.001)，而Lenstar与AL-SCAN的相关性不显著(r=0.453，P<；0.001)。Lenstar LS900型晶状体眼中央角膜厚度与Pentacam、Tomey EM-3000的相关性均很好(r分别为0.817、0.882，P均为0.001)。
PurposeTo test whether some biometry measurements provided by the Lenstar LS900 compared well with the AL-Scan, Pentacam rotating Scheimpflug camera, Ultrasound Biomicroscopy (UBM) and Tomey EM-3000.MethodsTwo hundred and one patients having routine cataract surgery had standard preoperative assessment. In this clinical study, the axis length (AL) and lens thickness (LT) were taken by Lenstar LS900 and AL-Scan; anterior chamber depth (ACD) was taken by Lenstar LS900, A-Scan, Pentacam and UBM; central corneal thickness (CCT) was taken by Lenstar LS900, Pentacam and Tomey EM-3000. The results were compared using a Wilcoxon–Mann–Whitney U test and Pearson correlation calculations. Agreement was assessed through intraclass correlation coefficients and Bland–Altman plots.ResultsThe highest correlation was found between Lenstar and AL-Scan for AL (r = 0.975; P < 0.001). For LT measurements, the correlation between these two devices was also good (r = 0.699; P < 0.001). Excellent correlations were showed between Lenstar and Pentacam or UBM for ACD (r = 0.948, 0.704, respectively, both P < 0.001), but not between Lenstar and AL-Scan (r = 0.453, P < 0.001). The correlations of CCT between Lenstar and Pentacam or Tomey EM-3000 were both excellent (r = 0.817, 0.882, respectively, both P < 0.001).ConclusionsIn phakic eyes of cataract patients, measurements of AL, LT, ACD and CCT from Lenstar LS900 yielded results that correlated very well with other clinical instruments.
