SECTION 4
Tono-Pen XL Operation
4.1 Instrument Preparation
Prior to using the Tono-Pen XL for IOP measurement prepare
the instrument according to the instructions below.
Allow the instrument to thermally stabilize at room
temperature (72-82° F, 22 - 28° C) for approximately 30
minutes prior to use.
Remove the Ocu-Film Tip Cover from the probe. Visu-
ally inspect the tonometer’s probe tip for cracks, chips or
other irregularities. If irregularities are present, contact
Medtronic (see Section 7). Do not use the instrument.
If the probe tip passes a visual inspection, proceed.
To help prevent build-up of debris around the probe
post, spray the probe tip with compressed gas before the
fi rst use of the day.
Cover the Tono-Pen XL probe tip with a new Ocu-
Film Tip Cover. Medtronic Ocu-Film Tip Covers are:
• Individually wrapped and sterilized.
• For Single Use only.
• May be gas sterilized for intraoperative use.
Perform daily routine calibration.
*Note: Calibration should only be performed on the Tono-
Pen once daily, unless otherwise indicated by the instrument.
 e Tono-Pen does not require calibration a er every patient
examination.
