Instrument Overview
Thank you for purchasing the Humphrey Matrix® Visual Field Instrument, featuring
Frequency Doubling Technology.
The Humphrey Matrix Visual Field Instrument is an innovative, efficient, and compact
automated visual field testing instrument. Years of research and clinical trials of the
patented Frequency Doubling Technology have resulted in an instrument that provides
rapid, clinically validated and user-friendly visual field testing.
Frequency Doubling Technology (FDT)
Frequency Doubling Technology (FDT) isolates a subset of low redundancy, retinal ganglion
cell mechanisms in the magnocellular (M-cell) pathway. These M-cells have large diameter
fibers and comprise only 3% to 5% of all retinal ganglion cells. Damage to these cells, for
example in the glaucoma disease process, is detected by Frequency Doubling Technology.
Key features of the Humphrey Matrix:
• World-class clinical validation by leading researchers in the field
• Statistically significant correlation to the Humphrey Field Analyzer
• Extensive age-normative reference database
• Accurate & reliable supra-threshold screening tests in less than 1 minute per eye
• Full-threshold test results in five minutes per eye
• 24-2, 30-2, 10-2, N-30 and Macula FDT full-threshold tests
• FDT N-30 threshold and screening tests
• Video eye monitoring for patient alignment and fixation monitoring
• Easy to use; no special operator training or certification is needed

Matrix Instrument Software
Carl Zeiss Meditec pre-installs all software necessary to operate the Matrix System
instrument. Software updates with installation instructions may be provided on CD or on
the Matrix section of our website (www.meditec.zeiss.com/matrix).
Data Storage
We recommend archiving data to a network file server. For non-networked environments,
an external USB hard drive can be used.
CAUTION: We do not recommend that you use optical disks for long-term data
storage or backup. Use should be limited to data transfer between systems. Take
care to protect these media from damage. We recommend you use hard plastic
cases when transporting and shipping these media. Optical disks are very
susceptible to scratches that could render them unreadable.
External Device Equipment
WARNING: To maintain patient safety, if the instrument is externally
connected to non-medical peripheral devices (i.e. printer, storage devices,
etc.), the complete system must continue to meet the applicable medical
requirements of IEC 60601-1 safety standard. This standard requires the
usage of an Isolation Transformer to power the non-medical peripheral
device if located within 1.5 m from the patient. If the peripheral device is
located outside the patient environment (beyond 1.5 m) and is connected
to the Matrix 800, a separation device must be used or there shall be no
metal to metal connection between the non-medical peripheral device and
the Matrix 800.
The person or the responsible organization connecting additional devices
or reconfiguring the system must evaluate the complete system to ensure
compliance to the applicable IEC 60601-1 requirements. The instrument
operator must not attempt to touch the patient and the peripheral device
simultaneously.
Failure to observe this warning could result in electrical shock to the
patient and/or examiner.
WARNING: Accessory equipment connected to the analog and digital
interfaces must be certified according to the respective IEC standards
(e.g., IEC 60950 for data processing equipment and IEC 60601-1 for medical
equipment).
Printers
See Chapter (9), Printer Configuration for more information.

Humphrey Matrix User Manual 2660021138935 Rev. F 2015-11
Introduction 1-11
Isolation Transformer
The Matrix instrument is designed with an integrated Isolation Transformer intended to
power an external printer through the power outlet on the Matrix. Any additional isolation
transformer used to power other peripheral devices must be approved for medical use and
must have a minimum rating that is sufficient for the device(s) being powered. CZM highly
recommends contacting your CZM representative for an isolation transformer qualified for
the Matrix.
Note: Technical support is not provided for accessory devices that have not been qualified
by CZM.
