ArcScan Insight 100 VHF数字超声扫描仪是一种新型眼部超声测量仪，可对眼前节进行检查和测量，可用于角膜屈光手术前后的筛查和随访、ICL植入术术前眼前节参数的测量、拱高的预测和术后观测、圆锥角膜的早期筛查及青光眼、白内障、眼外伤等检查诊断，兼具超声生物显微镜(UBM)检查范围广、光学相干断层扫描(OCT)操作简便的特点，具有广泛的临床应用前景。本文就ArcScan Insight 100 VHF数字超声扫描仪的测量原理、使用方法、测量参数及临床应用新进展进行综述。

ArcScan Insight 100 very high-frequency(VHF)digital ultrasound scanner is a new ocular ultrasonic measuring instrument, which can detect and measure the anterior segment. It can be used for screening before corneal refractive surgery and follow-up after corneal refractive surgery, measuring anterior segment parameters before implantable collamer lens(ICL)implantation, predicting preoperative vault, measuring postoperative vault, early screening keratoconus, and diagnosing glaucoma, cataract and eye injuries, etc. Taking the advantages of a wide range examination of ultrasound biomicroscope(UBM)and simple operation of optical coherence tomography(OCT), it has a broad prospect for clinical application. In this paper, the measurement principle, application method, parameters and clinical application progress of ArcScan Insight 100 VHF digital ultrasound scanner are reviewed in detail.
