Measuring A Patient
Overview
The Accutome A-Scan Plus Connect is very simple to operate, and has advanced
features to help you obtain the best possible measurements.
The Accutome A-scan Plus Connect takes measurements by sending a signal
through the eye through the ultrasonic probe. The signal echoes off various parts
off the eye (cornea, lens, retina) and returns a signal through the probe. The
return signal is translated and displayed as a patient waveform. The Accutome
A-scan Plus Connect examines each of the echoes in the waveform and
calculates measured axial length. The number of echoes detected is determined
by the selected eye type.
Five waveforms can be captured for each eye. Review of the scan and gate
adjustment can be done after waveform capture to ensure proper measurement.
The Accutome A-scan Plus Connect provides many user controls to obtain
accurate measurements.
These include the support for contact or immersion, independent velocities,
automatic capture, automatic alignment indicators, gain control, and manual and
automatic capture settings.
During the measurement, the instrument will provide audible feedback of
contact and capture.
This chapter provides you with information to control, capture, and review wave
forms.
