CW-Pulse
CW-Pulse allows you to select either a single, continuous-wave pulse or repetitive pulses. CW-Pulse is
active after each key start.
MicroPulse (SLx Only)
MicroPulse (μP) delivers laser energy in a burst of very short pulses and separating intervals. You may
adjust MicroPulse duration and MicroPulse interval or select from three preset duty cycle values.
Duty cycle refers to the percentage of time the treatment laser is activated during each pulse; duty
cycle is calculated according to this formula:

Specific Warnings and Precautions
It is essential that the surgeon and attending staff be trained in all aspects of the use of this equipment.
Surgeons should obtain detailed instructions for proper use of this laser system before using it to
perform any surgical procedures. For additional Warnings and Cautions, see “Warnings and
Cautions” in this chapter. For clinical information, see “References” in this chapter. Proper eye
protection must be utilized for the specific treatment laser wavelength in use (810 nm).
Warnings and Cautions
DANGER:
Do not remove covers. Shock hazard and accessible laser radiation. Refer servicing to qualified laser
personnel. Risk of explosion if used in the presence of flammable anesthetics.
WARNINGS:
Lasers generate a highly concentrated beam of light that may cause injury if improperly used. To
protect the patient and the operating personnel, the entire laser and the appropriate delivery system
operator manuals should be carefully read and comprehended before operation.
Never look directly into the aiming or treatment beam apertures or the fiber-optic cables that deliver
the laser beams, with or without laser safety eyewear.
Never look directly into the laser light source or at laser light scattered from bright reflective surfaces.
Avoid directing the treatment beam at highly reflective surfaces such as metal instruments.
Ensure that all personnel in the treatment room are wearing the appropriate laser safety eyewear.
Never substitute prescription eyewear for laser safety eyewear.
To avoid the risk of electric shock, this equipment must be connected to a supply mains with protective
earth.
US federal law restricts this device to sale by or on the order of a healthcare practitioner licensed by the
law of the State in which he/she practices to use or order the use of the device.

6 IRIDEX OcuLight®SL/SLx Operator Manual 13099-EN Rev F
Use of controls or adjustments or performing of procedures other than those specified herein may result
in hazardous radiation exposure.
Do not operate the equipment in the presence of flammables or explosives, such as volatile anesthetics,
alcohol, and surgical preparation solutions.
Laser plume may contain viable tissue particulates.
Keep the protective cap over the fiber-optic connector when the delivery device is not in use.

Choosing a Location
Choose a well-ventilated location within the specified operating range of the console.
Place the laser system on a table or on existing operating room equipment. Allow at least 5 cm (2 in.) of
clearance on each side.
In the US, this equipment must be connected to an electrical supply source at 100-240 VAC with a
center tap.
To ensure that all local electrical requirements can be met, the system is equipped with a hospital-
grade (green dot) three-wire grounding plug. When choosing the location, ensure that a grounding-
type AC outlet is available; it is required for safe operation.
The power cord included in the packaging is appropriate for your location. Always use an approved
three-wire grounding cord set. Do not alter the power inlet. To ensure proper grounding, follow local
electrical codes before installing the system.
CAUTIONS:
Do not defeat the purpose of the grounding pin. This equipment is intended to be electrically grounded.
Contact a licensed electrician if your outlet prevents you from inserting the plug.
Do not position or use the system near open flames.
Connecting the Components
NOTE: Refer to the appropriate delivery device manual for specific connection instructions.
NOTE: The Auxiliary Output contact supports low-voltage electrical signaling circuits of up to five amperes
and 24 volts AC or DC. Ensure all wiring conforms to local electrical codes.

representative.
Inadequate or no aiming beam • Verify that the delivery device is properly connected.
• Verify that the console is in Treat mode.
• Turn the aiming beam control fully clockwise.

console in Treat mode.
If the aiming beam is still not visible, contact your local IRIDEX Technical
Support representative.
No treatment beam • Verify that the remote interlock has not been activated.
• Verify that the aiming beam is visible.
• Verify that the fiber switch is in the correct position for the laser system
and wavelength you are using.
• Verify that the eye safety filter is in the closed position.

No illumination light
(LIO only)
• Verify that the illumination connector is connected to the console.
• Verify that the special function control is not between detents.
• Check the bulb and replace it (if necessary).
Illumination light is too dim
(LIO only)
• Verify that the special function control is not between detents.
• Adjust the console illumination intensity control.
The aiming beam is large or out of
focus on the patients’ retina
(LIO only)
Readjust your working distance between the LIO headset and the
examination lens. The aiming beam should be sharply defined and at its
smallest diameter when in focus.

The treatment lesions are variable
or intermittent (LIO only)
• The LIO may be slightly out of focus. This decreases power density.
Readjust your working distance to obtain the smallest spot size.
• A poorly centered laser beam may be clipping on the examination lens or
on the patient’s iris. Adjust the laser beam in the illumination field.
• The laser treatment parameters may be too close to the tissue response
threshold for consistent response. Increase the laser power and/or
exposure duration, or select a different lens.
Does not fit on the mounting plate
(OMA only)
• Inspect and clean the mounting plate.
• Verify that the mounting plate corresponds to your microscope.
Laser and viewing systems are not
focussed at the same point
(OMA only)
• Verify installation of a 175 mm microscope objective lens on the
microscope.
• Turn on the aiming beam to determine focus position and adjust as
necessary.
View is blocked or partially blocked
by OMA (OMA only)
Set magnification to 10X or more.
