[摘要]
近年来，各种眼部生物参数测量仪不断改进和更新，如非接触式光学相干生物测量仪(intraocular len-master，IOL Master)、超声生物显微镜(ultrasound biomicroscope，UBM)、Pentacam眼前节综合分析系统(Pentacam)、光学相干断层成像术(optical coherence tomography，OCT)、Orbscan裂隙扫描角膜地形图(Orbscan)、Lenstar LS900光学生物测量仪(Lenstar LS900)、伽利略双通道Scheimpflug眼前节分析仪(Galilei)、角膜内皮显微镜(specular microscope)、共聚焦显微镜(confocal microscope)等，每一种测量仪的测量原理及临床应用范围各有不同。本文主要对新型的基于低相干光反射(optical low coherence reflectometry，OLCR)原理设计的非接触式的光学生物测量仪Lenstar LS900的测量原理、使用方法及临床应用进展进行综述。

[Abstract]
There are many new instruments used to measure biometric measurements in recent years, such as intraocular len-master(IOL Master), ultrasound biomicroscope(UBM), Pentacam, optical coherence tomography(OCT), Orbscan, Lenstar LS900, Galilei, specular microscope, confocal microscope, and so on. Among these instruments mentioned above, the principle and clinical application are different. This article will review the principle, usage, clinical application of the Lenstar which is a new optical low coherence reflectometry device.
