晶状体厚度的在体精确测量对眼内调节及屈光不正发展机制的研究具有重大的应用价值，同时对于青光眼、白内障诊断及治疗方面有较大的临床意义。本文对目前用于晶状体厚度在体测量的超声法和光学法等多种仪器的测量原理、优劣势及准确性进行归纳总结，其中OrbscanⅡ、Pentacam、Lenstar、AS-OCT等可以代替A超测量晶状体厚度，而UL-OCT可以准确而动态地监测随调节改变晶状体厚度的变化。选择测量准确性较高的方法测量晶状体厚度，可为临床及科研提供更为准确可信的晶状体厚度数据。

[Abstract]
The precise measurement in lens thickness in vivo, provides great application value for intraocular accommodation and ametropia development mechanism research. And it has great clinical significance for the diagnosis and treatment of glaucoma and cataract. Currently, many ultrasonic methods and optical methods are used in measuring lens thickness. The measurement principles, advantages, disadvantages and the accuracy of the instruments are summarized in this paper. Among these methods, Orbscan II, Pentacam, Lenstar and AS-OCT can be used to measure lens thickness instead of A-scan. More important is the fact that UL-OCT can dynamically monitor the change of the lens thickness with intraocular accommodation. Choosing an instrument with higher measuring accuracy to examine the lens thickness, can provide more accurate and convincing lens thickness data for clinical and scientific research.
