1.4 Outline of operation
The AL-100 is an ultrasound instrument designed for measuring the
axial length of the eye for medical ophthalmic use.
Acoustic output is switched off after measurement.
Ultrasound energy is emitted from the probe tip. The probe
acts as both the transmitter and receiver of ultrasound en-
ergy.
This instrument has auto-measurement and tone-monitor-
ing function which makes the operator easy to operate.
IOL power calculation can be performed immediately after
measuring the axial length. Six atandard IOL formulae are
provided.
The instrument can store axial length and implanted IOL
data and each customer can calculate personal A constants
with these values.
