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.
• 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.
If there is still no treatment beam, contact your local IRIDEX Technical
Support representative.
No illumination light • 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 • 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
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
• 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.
