INTRODUCTION
The PACSCAN™ series is the latest generation
ophthalmic biometry instruments introduced by
industry leading Sonomed. The series consists of
three different models:
¾ PACSCAN™ 300A. This A-scan system
allows for measuring the axial length
(AXL), anterior chamber depth, and lens
thickness of an eye and for calculating the
associated IOL power for an implanted lens.
¾ PACSCAN™ 300P. This Pachymeter system
allows for measuring and mapping corneal
thickness.
¾ PACSCAN™ 300AP. This system seamlessly
integrates the A-Scan and Pachymeter
capabilities into a single system.
All systems utilize a high-resolution backlit
touch screen liquid crystal display (LCD) by
which the user can enter information and view
data and calculations. The system is compact
and lightweight thereby making the system
extremely portable, and the adjustable legs can
be tilted to several angles for user comfort.
This manual is intended to provide a thorough
overview of the P
ACSCAN™ series of
instruments and their capabilities. Please also
feel free to contact Sonomed customer service at
1-800-227-1285 at any time with questions or
concerns regarding system use.
Thank you for your trust in Sonomed to provide
for your ophthalmic biometry needs.

A-SCAN FEATURES
(For 300A and 300AP Models Only)
As mentioned, the A-Scan mode of the
P
ACSCAN™ series allows for measuring the
axial length (AXL) of an eye and calculating the
IOL power for an implanted lens.
By placing the A-probe against a patient eye, 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
measurement, the 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 optional thermal printer. The
record to be printed may include the A-Scan
image, table of IOL powers versus refraction,
patient information, and user information.
Several features help to distinguish the Sonomed
P
ACSCAN™ series including:
¾ Live A-Scan Display
¾ Gain Control
¾ Storage of 5 Scans for Later Review and
IOL Calculation
