Potential Side Effects or Complications
Ophthalmic
• Specific to retinal photocoagulation: inadvertent foveal burns; choroidal neovascularization;
paracentral scotomata; transient increased edema/decreased vision; subretinal fibrosis;
photocoagulation scar expansion; Bruch’s membrane rupture; choroidal detachment; exudative
retinal detachment; pupillary abnormalities from damage to the ciliary nerves; and, optic neuritis
from treatment directly or adjacent to the disc.
• Specific to laser iridotomy or iridoplasty: inadvertent corneal or lens burns/opacities; iritis; iris
atrophy; bleeding; visual symptoms; IOP spike; and, rarely, retinal detachment.
• Specific to laser trabeculoplasty: IOP spike, and, disruption of the corneal epithelium.
ENT
Excessive treatment may cause swelling (edema) in the area treated by the laser.
Anesthesia Considerations
One of the main concerns during otolaryngeal and bronchial procedures is the substantial risk of
endotracheal fires. The following sections provide information and safety guidelines, which can
greatly decrease the risks associated with these procedures. Information is also provided on what to
do if such a fire does occur.
IRIDEX Corp. recommends the safety guidelines of American National Standards ANSI Z136.3-2007
as follows:
• Care must be taken to protect endotracheal tubes from laser radiation. Ignition or perforation of
endotracheal tubes by the laser beam could result in serious or fatal patient complications.
• Use the lowest possible oxygen concentration to support the patient.
• Use the venturi ventilation technique when possible.
• Use intravenous anesthetic agents rather than inhalation techniques.
• Use non-flammable laser-safe endotracheal tubes.
• Protect the endotracheal tube cuff with wet cottonoids.
Reference material and additional information regarding laser safety and the prevention of
endotracheal fires may be obtained from the following U.S. sources:

2007.

Specific Contraindications
• None known specific to ENT use at this time.
•Ophthalmic:
– Any situation where the target tissue cannot be adequately visualized or stabilized.
– Do not treat albino patients who have no pigmentation.
Laser Settings
Beginning at low power with short duration exposures, the surgeon should note the surgical effect
and increase power, power density, or exposure duration until the desired surgical effect is obtained.
The information in the following tables is intended to provide guidance only for treatment settings,
which are not prescriptive for any condition. The operative needs of each patient should be
individually evaluated based on the indication, treatment location, and on the patient’s medical and
wound healing history. If uncertain of expected clinical response, always start with a conservative
setting and increase the setting in small steps.

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.
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
CAUTION: Do not connect two footswitches to the laser console.
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.

General Problems
Problem User Action(s)
No display • Verify that the keyswitch is on.
• Verify that the components are properly connected.
• Verify that the electrical service is on.
If there is still no display, contact your local IRIDEX Technical Support
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.
• Verify that the fiber-optic connector is not damaged.
• If possible, connect another IRIDEX delivery device and place the
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.
• If using Symphony Slit Lamp Adapter, verify that the Wavelength Switch is
in the correct position for the desired laser system.
• Verify that the eye safety filter is in the closed position.
If there is still no treatment beam, contact your local IRIDEX Technical
Support representative.
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.
