• For the defragmenter to complete in a reasonable amount of time (overnight),
processes that write to the hard drive should not be running. Otherwise, the
defragmenter will restart repeatedly because the hard drive contents have changed.
Such processes include many screensavers. We suggest you disable screensavers
temporarily and turn off your monitor while the defragmenter is running.
Routine Cleaning
The forehead and chin rests, and to a lesser extent the ocular lens, are the only parts that
require routine cleaning.
Forehead and Chin Rests
The instrument parts that routinely contact the patient—the forehead and chin rests—
should be cleaned between each examination with an alcohol prep swab. These parts are
not removable. You also may use either a 2% glutaraldehyde solution or 1-10 bleach-water
solution for disinfection.

Note: These latter disinfectants are skin irritants, so be sure to rinse repeatedly and
thoroughly with a clean and soft wet cloth. Wipe dry with a clean and soft
non-linting cloth.
The Ocular Lens
The ocular lens of the Patient Module should not contact the patient's eye. It comes with a
lens cap to cover it when not in use. Still, it may contact the eyelashes during normal use,
and you should clean it to remove dust and oily smudges occasionally to ensure a true
Stratus OCT image. You may use an alcohol prep swab or cotton swab dipped in isopropyl
alcohol. (You may use the Volk Precision Optical Lens Cleaner.) Wipe dry with a soft,
non-linting cloth or tissue. If the lens inadvertently contacts the patient's eye, clean it
before proceeding with the examination.
Report Signs Of Wear
During normal use, the fundus illumination lamp may wear out and require replacement.
The power fuses may also require replacement when an unexpected power problem arises.
Although these are relatively simple parts, attempts by the user to access and replace them
may damage sophisticated precision hardware. In all cases, contact Carl Zeiss Meditec
customer service when there is a problem with the instrument, even if you suspect that only
these parts need replacement. In the U.S., call 1-800-341-6968. Outside the U.S., contact
your local Carl Zeiss affiliate or distributor. Only Carl Zeiss service engineers are authorized
to disassemble the instrument and replace any parts.
Fundus Illumination Lamp
Under normal use, the fundus illumination lamp should last for three years. The lamp may
need replacement when the fundus does not appear adequately illuminated despite proper
alignment of the Patient Module with the eye.
