E-Z S
CAN
5500+.
The A-Scan mode of the EZ-S
CAN
allows for measuring of the axial length (AXL)
of an eye and calculating the associated IOL
power for an implanted lens.
By placing the A-probe against a patient eye,
and aligning the probe along the visual axis, a
live A-Scan ultrasound pattern for an AXL
measurement can be obtained. The image can
then be “frozen” and the measured value for the
AXL will be displayed along with other
pertinent information. Using the AXL,
Keratometer readings, and an IOL program
parameter (depending on the specific program
selected), the system calculates the required IOL
power.
After completion of measurements and
calculations, a hardcopy may be obtained of the
results using the video printer included with the
system. The hardcopy will include all
information that is displayed on the screen when
the print key is depressed.
