Item 1: "File/Name" Issue
If an operator fails to follow the user instructions, and under a highly specific set of unusual
circumstances (further described below), then it is possible to have an incorrect patient name
associated with a visual field test performed on the Humphrey Field Analyzer II - i series with
system software revisions C2, C3, C3_MO or C3.1. For example, Patient A's name may be
matched with Patient B's test if all of the following circumstances are met:
If, during the course of testing a patient on your HFA II- i series:
the instrument encounters an error where the instrument did not restart,
•
and the patient being tested is not the first patient of the day to be tested, (ie, Patient B)
•
and you respond to the error message by selecting the "OK" button,
•
and you then select the "Test Other Eye" button,
•
then the instrument will revert to displaying the name of the last patient who completed a visual
field examination on the instrument (ie, Patient A).
If, after the above conditions occur, you do not observe the incorrect patient name displayed on
the screen:
and you elect to resume the examination,
•
and the test is completed successfully,
•
and you elect to save the test result,
•
and you select "Yes" in response to the message presented on the screen asking you to
•
confirm that the patient's name and date of birth are correct ["Do You Wish To Save This
Test For": (ie, "Patient A")], failing to observe the incorrect patient name displayed,
then the file saved will have the incorrect patient's name recorded. Additionally, if you chose to
print the visual field test results, the incorrect patient name would be printed on the visual field
test results.
Action Required: Install system software revision 3.2;
If you should have any files where you suspect that the patient's visual field result is not properly
associated with the patient's name, and if, after further investigation you determine that the file
must be updated, you may correct the file by completing the following steps:
Main Menu>File Functions>Change Patient Data>One Test>Select the Source (Hard Drive,
Floppy Drive)>Select Directory Order (Name, Date or Patient)> Proceed>Enter Name to
Find>Enter>Select the patient from the file directory>Proceed>Edit Patient
Information>Select Enter after each field is updated>Select Proceed. To exit the Change
Patient Data screen, select the Main Menu icon.
Note: You may wish to reprint the visual field test results with the correct patient information
recorded. Please be aware that merely installing the new system software revision 3.2 will not
check and correct any suspect files.
