Function and Intended Application
Thank you for purchasing the Welch Allyn SureSight™ Autorefractor. Please read
and follow the instructions found in this manual before using your new SureSight
to ensure accurate and reliable service.
SureSight is the child-friendly, portable autorefractor that lets you test patients -
including young children and adults - anytime, anywhere. Carry it from room to
room, to your waiting area, even off-site.
SureSight solves many of the problems you face when performing exams. You
can perform objective refraction from a non-threatening 14 inches (35 cm) away -
even through glasses and contact lenses. The unit’s flashing lights and sounds
engage the patient throughout the exam. There’s no intimidating equipment. No
cycloplegic drops to contend with. Just fast, easy refractions. That’s why
SureSight makes testing even your toughest patients quick and painless - for both
you and your patients.

First Time Set-Up
Stand
• Insert right angle connector into stand
• Optional: Two strips of hook and loop fasteners are provided on the stand.
Attach mating strips to countertop or “home” location of the stand. For best
results, clean surface and allow to dry before adhering. Hook and loop
fasteners keep stand firmly in place for use, while allowing it to be removed
as needed.
Battery
• Insert battery:
1) Open the battery cover located on the underside of the unit by sliding it in the
direction indicated by the arrow and lifting out.
2) Insert the new battery into the compartment in the direction of the arrow on
the battery itself, so that the terminal end enters the compartment first. If
necessary, rotate the lever obstructing the compartment in a clockwise
direction until the compartment is unobstructed. NOTE: Insert the battery
only as directed. Failure to do so will prevent the instrument from
functioning.
3) While pushing in on the battery, rotate the lever in a counter-clockwise
direction until it covers the battery.
4) Replace the cover by lightly pushing in on the raised end until it is level and
sliding the cover in the opposite direction of the arrow until it locks into place.

14
Plus or Minus Cylinder Convention
Your SureSight was set at the factory to the Minus Cylinder Convention. If you
wish to change your unit to the plus convention:
1) Open the battery cover located on the underside of the unit by sliding it in the
direction indicated by the arrow and lift up.
2) Rotate the lever holding the battery in and lift the battery from its
compartment.
3) View the DIP switches inside the battery compartment located on the button
side of the unit.
4) Using tweezers or another appropriate tool, pull the first switch (located on
the side of the unit with the handstrap) up towards the bottom of the
SureSight.
Diopter Power Resolution
Your SureSight was set at the factory to display power in 1/4 diopter increments.
If you wish to change to 1/8 diopter increments:
1) Open the battery cover located on the underside of the unit by sliding it in the
direction indicated by the arrow and lift up.
2) Rotate the lever holding the battery in and lift the battery from its
compartment.
3) View the DIP switches inside the battery compartment located on the button
side of the unit.
4) Using tweezers or another appropriate tool, pull the third switch (third from
side of SureSight with the handstrap) up towards the bottom of the
SureSight.

15
Controls
The buttons on the back of the instrument function as follows:
The instrument will turn off when unused for one minute. Any button pressed on
the SureSight will bring up results.

hild/Adult Calibration
• Clears readings
• Changes child/adult
Calibration by holding it down
Left/Right Toggle & Print
• Selects single eye to re-test
or switches back to regular
test.
• Prints results (hold button
down while aiming patient
side of SureSight at printer
until you hear “tah-dah”)
“GO” Button

Operating Instructions
• Push any button to turn on the unit.
• Position the patient so that eye levels can be adjusted for unit use.
• Press the child/adult button until you hear a beep to choose the appropriate
calibration. (Child/Adult Calibration cut over age is 6 - see Adult/Child
Calibration Section, Page 20 for more information).
• Explain the test procedure to the patient:
“Now I will check your eyes. (Or “Now I’m going to take movies of you.”)
“I want you to look for the red light in the middle of the blinking green lights.”
• Position yourself at eye-level and square with the face of the patient.
• Push the “GO” button on the unit and check that the patient is fixated
correctly during the test.
• Position the unit at the correct distance from the patient:
• When too far away, you will hear slow, low-pitched beeps.••••••
• Slowly move closer. When the unit is at the correct distance (~14”), you
will hear a steady, low tone.————
• When the unit is too close, you will hear quick, high-pitched beeps ……
• The cross hairs will flash in synch with the tones.
• When you are at the correct distance, look through the peephole and align
the cross hairs on the pupil of the patient’s right eye. While the unit is
acquiring data, you will hear a very high-pitched chirping sound with a steady
low tone. °°°°°
• When the test of the right eye is complete, you will hear the “tah-dah”
sound.
•Rotate the unit to the left eye and align the cross hair over the left eye’s pupil
and repeat. (Testing resumes 1 second after the first eye is complete, so you
do not need to press any buttons.)
• At the end of the test, you will hear the “tah-dah” sound again.
• If the unit has not gathered enough good readings from either eye, you will
hear 5 tones to signify that the testing has stopped. - - - - - You must re-test
that eye.
