PERFORMING A-SCANS (CONTACT)
WARNING: Exercise cauon when coming into contact with a paent’s eye. To avoid
potenal injury, use minimal pressure when applying the probe or adjusng its posion.
Only make minor posion adjustments while in contact with the eye. If signicant posion
adjustment is necessary, remove the probe from the eye and then reapply.
WARNING: Before each procedure, the ultrasound probe must be cleaned and disinfected.
Refer to the Cleaning and Disinfecon secon.
NOTE: Refer to the Alignment Ranking System and Video Buer Full secons for more
informaon on these topics.
1. Create a new paent or select an exisng paent on the Paent Screen.
2. Select the A-Scan Screen tab. If necessary, click the [CHANGE EYE]† buon to change the
eye being measured (OD or OS).
3. Select the “Contact” radio buon on the right-hand side of the screen. Select the name of
the Operator performing the measurement from the drop-down box.
NOTE: If the operator is not listed in the “Operator” drop-down box, add the new operator
by selecng Preferences > Operator and clicking the [NEW] buon.
4. Select the correct Lens and Vitreous type for the eye to be measured.
5. Adjust the compression lockout sensivity track bar (Comp) to the desired seng. Higher
Compression Sensivity will decrease the amount of error due to corneal compression, but
will make it more dicult to obtain measurements.
NOTE: Refer to Page 27 for more informaon on Corneal Compression Sensivity.
6. Seat or recline the paent in a posion comfortable for both Paent and Operator. Head
movement must be minimized during the exam. Anestheze the eye and have the paent
xate with both eyes on a spot on the ceiling or wall.
7. To Start scanning†: - Click the [START SCAN] buon; or
- Press the Space Bar (on the keyboard); or
- Press the Foot Pedal (Single Pedal accessory); or
- Press the Le Foot Pedal (Double Pedal accessory)
A waveform will be displayed on the screen, but the unit will not begin recording.
8. Stabilize the hand holding the probe to minimize indentaon of the cornea or
excessive movement. Typically, this can be done by resng a palm on the cheek or
forehead of the paent.
9. The transducer should be held perpendicular to the surface of the eye as it approaches the
cornea. Observe the approach from a vantage point that allows a view across the
topography of the eye. This method aids in seeing the exact moment when the probe
contacts the cornea, allowing the user to minimize indentaon of the cornea.
10. Gently apply the probe p to the center of the cornea. The unit will start beeping at the
moment of contact, which indicates coupling has been achieved. Minimize indentaon of
the cornea.
NOTE: Stopped or intermient beeping indicates that the probe p has been removed from
contact with the eye or is not properly coupled. Re-aempt applicaon of the probe.
†This command may be executed through voice control. Refer to the A-Scan Voice Controls secon.
