Clinical application of ArcScan Insight 100 very high-frequency digital ultrasound scanner in ophthalmology

Abstract

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.
