A-Scan Ultrasound Devices

Accurate measurement of the globe’s axial length is a critical factor in detecting disease and determining the power of the posterior chamber intraocular lens placed during cataract surgery. Devices that precisely measure the axial length are therefore important tools in the ophthalmologist’s armamentarium. Traditionally, these devices have consisted of stand–alone contact ultrasound A-scanners. However, manufacturers are now combining A-scan capabilities into other devices, such as pachymeters.
