Biometric measurement of the anterior segment is of great importance for the ophthalmology, human eye modeling, contact lens fitting, intraocular lens design, etc. This paper serves as a comprehensive review on the historical development and basic principles of the technologies for measuring the geometric profiles of the anterior segment. Both the advantages and drawbacks of the current technologies are illustrated. For in vivo measurement of the anterior segment, there are two main challenges that need to be addressed to achieve high speed, fine resolution, and large range imaging. One is the motion artefacts caused by the inevitable and random human eye movement. The other is the serious multiple scattering effects in intraocular turbid media. The future research perspectives are also outlined in this paper.

眼前节的生物测量对于眼科学、人眼建模、隐形眼镜适配、人工晶状体设计等领域具有重要意义。本文对用于测量眼前节几何轮廓的技术的历史发展和基本原理进行了全面综述。文中阐述了当前技术的优缺点。对于眼前节的活体测量，需要解决两个主要挑战，以实现高速、高分辨率和大视场成像。一个是由不可避免且随机的人眼运动引起的运动伪影。另一个是眼内混浊介质中的严重多重散射效应。本文还概述了未来的研究方向。
