Introduction
Dear User：
SW-1000 is a precise ultrasound measure instrument, designed for
detecting axial length, depth of anterior chamber, thickness of lens and
calculating the IOL.
This User’s Guide is designed as a training and reference manual.
We recommend you carefully read and follow the steps in this guide to
ensure that the machine would have optimum performance.
Classification
SW-1000 is classified as Class I, Type B instrument.
This product has got ISO9001 and CE approval.

Precaution
This instrument requires the power supply of AC 90~230V，
50HZ±2%. The power socket indoors should have ground line. If
the local power net could not fit the requirement, then we
recommend you to use regulated power supply. Improper power
supply may cause instrument damage or person injury.
All the accessories should be well kept. If anything is missing, the
instrument could not be warranted.
The instrument should be installed indoors with good ventilation
and avoid direct sun radiation, and kept away from strong magnetic
or electric field or other strong disturbance sources.
The probe is key, delicate and expensive. Do not stress it, knock it
or fall it from high place. Don’t dip it into alcohol to perform
disinfection. Don’t twist or pull the leading line violently.
It is not permitted that user himself dissembles the main unit or probe.
If there are any problems, please send it to the warranty station.
The maintenance and warranty of the printer is executed by the
warranty station near user’s location. We recommend you to send
the printer to warranty station periodically. That will make the
printer last longer.
Contraindication of A scan:
1. Infective eye disease, such as Keratitis and so on.
2. Open eye damage, such as avulsion or perforation of cornea
3. Children under 5 years old that could not cooperate with the
examination
When the ambient temperature is under 10℃, the instrument should
warm up for 5 minutes before it begins to work.
As to the safety and effective result caused by ignoring the
declaration above, our company does not take the responsibility.

Theory and Function
Ophthalmic A scan SW-1000 is composed of main unit, probe, pedal
and so on. The probe contacts the cornea and sends out ultrasound of
10MHz. The echo wave from front surface, back surface of lens and
retina is detected. The signal is processed and then we get the depth of
chamber, thick of lens and axial length. The data are transmitted to MP
(Micro processor). The values of A constant and K1, K2 are input from
keyboard. The MP automatically calculates the IOL according to the
chosen formula. The data are displayed on the color LCD screen through
output interface, or stored in the machine, or printed out.
This instrument is designed for detecting axial length, depth of
anterior chamber, thickness of lens and calculating the IOL. It has high
resolution and is easy to use, with the function of auto-calculating IOL
and touch screen input. Six groups of formula could be chosen: SKR-Ⅱ、
SKR-T、BINKHORST-Ⅱ、HOLLADAY、HOFFER-Q HAIGIS-STD. It has
manual and auto measure mode. The build-in printer could print the data
and IOL table.

Install and Connection
1. Check the package to see if
anything missing. (Reference to
Appendix: package list)
2. Insert probe, pedal and power
plug to respective socket. （See
Pic.3）
Align the salient on the probe
connector to the gap on the probe
socket, and plug it in. When you hear “click”, the probe is ready. The
probe must be treated gently following the steps above; otherwise it
may be damaged by improper operation.
The probe must be connected before power on. Don’t plug or pull the
probe when power is on.
Pedal is to freeze and unfreeze the image manually. Put the pedal at
handy place. Gently step once and it will be ok. Don’t use too much
strength or not let it go.
3. After each part is properly connected, turn on the power. You could
hear a “beep”. The measure interface will appear in a second,.
Do not turn on and turn off the power too swiftly. Otherwise on the
screen will appear random pictures.

Introduction of the Interface and Setting
1. Interface Introduction
Pic.4 measure interface
After switch on, “Measure” mode and “Contact” is default. See Pic.4.
Press ”Contact” to switch to “Immersion”.
1.1 On the upper part is the setting menu. Press the items to begin
setting up data.
DR* ：The recover degree after the
operation, set according to doctor’s
experience.
A：Constant A(auto stored after
each input)
K1：Horizontal diopter (auto stored after
each input)
K2：Vertical diopter (auto stored
after each input)
*: DR＝1.00 means the eyesight is expected to recover to 100
