EnFocus OCT / 9054-10063_EN / Revision K-00 7
Safety notes
3.6.2 Laser Safety
WARNING
Danger of eye injury due to laser radiation.
This device is a Class 1 Laser product.
Use of controls or adjustments or performance of
procedures other than those specied herein and any
companion documents may result in hazardous radiation
exposure.
X Do not operate the system when the ber optic cable is
removed from the optical ber port.
X Do not look directly in to the optical ber port.
X Do not remove the optical ber while the system is
powered on.
X Turn o power before removing the optical ber.
The following Photo toxicity cautions are mandatory text as defined
in the CDRH guidance document #1241, “Ophthalmoscope Guidance
(Direct and Indirect).
CAUTION
Photo toxicity.
Because prolonged intense light exposure can damage the
retina, the use of the device for ocular examination should
not be unnecessarily prolonged, and the brightness setting
should not exceed what is needed to provide clear
visualization of the target structures. This device does not
emit optical radiation outside of the near infrared
wavelength region 770nm – 1100nm.
CAUTION
Photo toxicity.
The retinal exposure dose for a photochemical hazard is a
product of the radiance and the exposure time. If the value
of radiance were reduced in half, twice the time would be
needed to reach the maximum exposure limit.
CAUTION
Photo toxicity.
While no acute optical radiation hazards have been
identied for direct or indirect ophthalmoscopes, it is
recommended that the intensity of light directed into the
patient's eye be limited to the minimum level which is
necessary for diagnosis. Infants, persons with aphakia and
other diseases of the eyes will be at greater risk. The risk
may also be increased if the person being examined has had
any exposure with the same instrument or any other
ophthalmic instrument using a visible light source during
the previous 24 hours. This will apply particularly if the eye
has been exposed to retinal photography.
The following cautionary statement is mandatory text as defined in
ISO15004-2:2007 for Group 2 ophthalmic instruments.
CAUTION
Photo toxicity.
The light emitted from this instrument presents a potential
thermal hazard to the cornea and lens. The longer the
duration of exposure, the greater the risk of ocular damage.
The maximum corneal and lenticular infrared radiation
irradiance emitted from this instrument is 95mW/cm² when
operated at worst case conditions (i.e., no eye movement
and with non-scanning beam). This value is 5% below the
safety guideline (100 mW/cm2) specied in ISO15004-2:
2007.
The EnFocus™ Spectral Domain Ophthalmic Imaging System (SDOIS)
complies with the Group 2 instrument requirements of ISO 15004-
2:2007.
CAUTION
Risk of injury to the retina due to prolonged light exposure.
X Do not unnecessarily prolong the use of the device for
ocular examination.
CAUTION
Thermal hazard to the cornea and lens.
X To limit the risk of ocular damage do not unnecessarily
prolong the duration of exposure.

EnFocus OCT / 9054-10063_EN / Revision K-00 17
EnFocus Components
4.1.1 Optical Engine
The EnFocus OCT engine contains the optical and electrical
components associated with signal acquisition, detection and
processing. A fail-safe circuit that monitors the scanner is also
included inside the engine. If a scanner fault signal is detected or
the system is not scanning, the fail-safe circuit shuts down power
to the OCT light source, a superluminescent diode (SLD).
The engine contains a power indicator light showing that the
system is on or off.
4.1.2 Scanner
The scan head of the EnFocus OCT system is intended to be
mounted to the optics carrier of compatible surgical microscopes
for imaging during surgical procedures.
The scan head includes an aperture, allowing undisturbed
transmission of visible optical signals during concurrent OCT scans
while viewing through the microscope oculars. The OCT signal is
coupled into the microscope path with a dichroic filter reflective in
the OCT wavelength and transmissive in the visible waveband.
The scan head works with objective lenses that operate with a
working distance approximately equal to the focal length of
common surgical objective lenses.
The scanning OCT beam of the scanner is substantially telecentric,
and may be used with supplementary optics (such as wide angle
viewing systems for vitreoretinal procedures) between the
objective lens and the patient, as long as the supplementary optics
are transparent in the OCT waveband.

4.1.3 Computer
The computer has 1 TB of storage capacity on mirrored disks
(RAID 1), 16 GB RAM and a video card with 2 GB of dedicated RAM.
The computer operates on a Windows platform installed on a
dedicated hard drive that is separate from the data drives, and
supports Computer System recovery, and data integrity in case of
an operating system corruption.
The system includes a computer monitor, keyboard, and mouse.
The monitor is secured to the mobile cart with an adjustable
mounting arm that moves fluidly in X, Y, and Z directions.
The IEC 60601-1 compliant keyboard is sealed in water-proof
silicone which may be disinfected.
4.1.4 Foot Pedal
Microscope Integrated Foot Pedal
If the EnFocuss connected to a microscope with an integrated
communications interface, the microscope's foot pedal can be used
to execute OCT functions. Please refer to the associated microscope
user manual for details.

4.1.5 Cables
WARNING
Risk of Unspecied Accessories/Cables.
X Use of accessories, transducers and cables other than
those specied or provided by the manufacturer of this
equipment could result in increased electromagnetic
emissions or decreased electromagnetic immunity of
this equipment and result in improper operation.
Standard System Cables
The system uses the following cables for operation:
Cable Length Description
Mains 16' [5m] Permanently attached mains input power
cable
EnFocus
2-button
Foot pedal
8.8' [2.7m] Foot pedal USB cable to the system
Scan head 27' [10m] Fiber optic cable, connection between the
scan-head module and cart
Only Leica approved and provided cables are to be used for
these connections. Use of unapproved cables may degrade
the performance of your system displays.
4.1.6 Cart
The EnFocus Cart Configuration has the Optical Engine and Scanner
installed on a mobile cart with lockable casters to prevent
unwanted movement.
The cart provides cable management and contains a UPS that is for
the use of the EnFocus system only. All cables are provided with the
system and are not user interchangeable.
The cart computer has a front panel with a system power switch
and data ports.
4.1.7 USB ports
The computer installed in the cart provides access to bus-powered
memory devices. The panel behind the front of the computer has
two 2.0 USB ports for accessing data on the system and a power
switch. There are two 3.0 USB ports at end of the glove box.
WARNING
Risk of electrical shock.
The USB ports are not electrically isolated.
X Only use the USB ports with bus-powered devices such
as ash drives.
X Do not use the USB ports with any device that connects
to an external power source.
4.1.8 Video input ports
WARNING
Risk of electrical shock.
The rear video input ports are not electrically isolated.
X Only use the rear video input ports with medical grade
microscope cameras.
EnFocus supports the ability to stream microscope video into the
OCT software.
The system provides video input ports for DVI, HDMI, and S-video
formats at the back of the cart to interface to a medical grade
microscope camera only. The incoming video is used to co-register
the OCT scan with the surgical microscope field of view. Note that
only one port may be used at any given time. The appropriate video
cable, as determined at the time of purchase, is provided with the
system.
The following camera controllers are compatible with the Enfocus
system: Leica HDC100, Leica HDC300, Panasonic GP-US932, and
Sony PMW-10MD.
