1.1 Precautions for operation
䕔 When measuring the axial length, fully examine the measured data for
waveforms and variations. If the measurement result is doubtful,
perform measurement again or another inspection to review the
inspection result. If incorrect measurement data is used to select
intraocular lenses, further surgery might be required.
䕔 When using the IOL calculation result to select intraocular lenses,
thoroughly determine the selection by also examining cataract
surgery methods and other inspections.
䕔 When measuring corneal thickness, the measurement accuracy may
exceed ±5 μm depending on the conditions of measurement or
patient's corneal. Carefully consider the history of corneal diseases
and surgeries, and review the inspection result by performing
measurement again or another inspection if the measurement result is
doubtful.
䕔 Only allow qualified operators to use the instrument.
䕔 Artifacts may occur in the ultrasonic measurements.
If measurement values are questionable, determine the values by
overall judgment (using the wave forms or results from other
equipment).
