title: Digital A-scan ultrasonography used to measure ocular distances.
abstract: Digital A-scan ultrasonography provided a digital display of intraocular distances with an overall accuracy of 0.05 mm. Since the control setting was easy and calibration was unnecessary, the time of measurement is reduced and hence the apparatus is useful in clinical practice.
