Introduction & Instrument Setup
Humphrey Field Analyzer II-
i
series User Manual 2660021145640 A
1-22
For patients who require a trial lens, the Model 750
i
uses Head Tracking and Vertex Monitoring to
help ensure that the patient’s eye is both centered b
ehind the lens and is held at the proper distance
from the lens. These features help to eliminate the trial lens as a possible sour
ce of unreliable visual
field results.
Data Protection Features
Visual field results need to be saved a
nd protected for future use. The HFA II-
i
offers you a number
of data storage methods to file the results. Five USB ports are provided for connection to USB
devices, two of which may be used simultaneously with USB storage devices. Floppy disk data
storage is available with an optional USB floppy disk drive. Using HFA-NET Pro, you can either
archive or back up vital test results to a network file server in your office. There are a number of
additional data protection features that work internally to safeguard your data from loss or serious
damage. This manual describes in great detail the procedures for creating extra copies of your data.
Refer to Chapter (11), "Database Management," for further information on database security. Refer
to Chapter (14), "Networking," for further information about connecting your HFA II-
i
into your
office computer network.
Risks of Internet Connectivity
CAUTION: When connected to the Internet, th
e HFA instrument may be vulnerable to
serious security risks, including viruses and worms that could disable your system or
adversely affect its performance. Internet connectivity enables third party software
drivers and updates to be downloaded to your system, either automatically or
intentionally. Installation of any unapproved software, including drivers, could
degrade the performance of the instrument and/or lead to corrupted diagnostics or
therapeutic information and may void the instrument warranty.
Networking Features

i
series perimeters offer many useful networking capabilities for patient data, test data, and
image files. These include:
• export patient data, test results, and image files (PDF and
TIFF format) to a file server
• synchronize databases on two or more HFA II-
i
perimeters via archiving and retrieval
• back up patient data and test results to a
file server for safe external storage
• restore patient data and test results from a
network file server to an HFA II-
i
• import work lists from non-DICOM and DICOM EMR/PMS systems
• import patient information and exam data from a DICOM system (DICOM Gateway 2.0 only)
• export patient data, image files, and test r
esults to non-DICOM and DICOM EMR/PMS systems
