目的：比较三种非接触式器械-IOLMaster、扫描周边前房深度分析仪（SPAC）和Visante前段光学相干断层扫描（AS-OCT）的前房深度测量结果。方法：对新加坡社区诊所就诊的497名50岁以上有晶状体眼受试者进行前瞻性横断面研究。由同一研究者使用所有三种技术测量右眼的前房深度。从角膜上皮到前透镜表面进行深度测量。结果：232名男性和265名女性接受了检查（平均（SD）年龄，63.4（7.9）岁）。IOLMaster的平均前房深度为3.08（0.36）mm，SPAC为3.10（0.44）mm，AS-OCT为3.14（0.34）mm。
Aim: To compare anterior chamber depth measurements by three non-contact devices - the IOLMaster, scanning peripheral anterior chamber depth analyser (SPAC), and Visante anterior segment optical coherence tomography (AS-OCT)Methods: Prospective, cross sectional study of 497 phakic subjects over 50 years of age attending a community clinic in Singapore. Anterior chamber depth of the right eye was measured using all three techniques by the same investigator. Depth measurements were made from the corneal epithelium to the anterior lens surface. The values obtained were compared using Bland - Altman analysis.Results: 232 men and 265 women were examined (mean (SD) age, 63.4 (7.9) years). Mean anterior chamber depth was 3.08 (0.36) mm with IOLMaster, 3.10 (0.44) mm with SPAC, and 3.14 (0.34) mm with AS-OCT. A significant difference was present between the anterior chamber depth measurements recorded by the three devices (p
