Instructions for Use (Continued)
Start Measuring Central Corneal Thickness (CCT) Measurement
Preparation of the Patient
The patient should be in a seated position. It may be helpful to explain that they should relax and attempt not to blink as
the probe is going to gently contact their eye. A drop of ocular anesthetic should be placed in the eye or eyes that are
going to be measured. If the patient has dry eyes, a moisturizing drop may also be used.
Acquiring a Measurement
On the start up screen, Tap: Start Measuring.
CAUTION: DO NOT USE THE ULTRASOUND PROBE AS A STYLUS. THIS WILL CAUSE DAMAGE TO THE PROBE AND
VOID THE IOPAC WARRANTY.
The Measuring screen shows both the right (OD) and left (OS) eyes. The instrument will default to the right (OD) eye.
You can switch the eye that you want to measure by tapping either the OD or OS box at the top of the screen.
To start measuring, tap: Start. You will hear a beeping sound to let you know the
Pachymeter is taking measurements. You may stop measurement acquisition
early by tapping the Stop button. Tapping the Cancel button will cancel
measuring and bring you back to the main screen.
Place the tip of the probe on the center of the cornea. Once the probe is
perpendicular to the cornea the Pachymeter will acquire up to 8 (eight)
measurements. A successful measurement is signaled by a high tone. An
unsuccessful measurement (caused, for example, by the probe not being placed
correctly) is signaled by a lower pitched tone.
After a set of measurements is made the eye selection will
automatically switch and will be highlighted in blue. To
change selection, tap on the appropriate column box to
select the left or right eye and follow the above procedure.
A mean thickness in microns and standard deviation
(shown in brackets) will appear after completion of the
measurements.
Review the measurements of both eyes. You can eliminate any measurement
from the mean and standard deviation calculations by tapping on the check
mark in the box next to the measurement reading that you want to eliminate.
The mean and standard deviation will update accordingly.
To retake a measurement, select the eye (OD or OS) that you want to retake,
and tap the Start button.
