Introduction: The Novus Spectra Laser
The Novus
®
Spectra
™
532-nm green laser is the benchmark for ease, speed,
and intricate treatment in ophthalmic surgery, integrating the reliability of
532-nm green light with the convenience of a small, portable laser package.
The adaptability of the Novus Spectra is ideal for ophthalmic procedures such
as angle-closure glaucoma, open-angle glaucoma, diabetic retinopathy, retinal
detachments, and age-related macular degeneration. It also is ideal for otologic
procedures such as stapedotomy, stapedectomy, tympanoplasty, myringotomy,
bleeding control, lysis of adhesions, and treatment of soft tissue adhessions.
Our complete line of delivery systems and accessories further extends the
versatility of the Novus Spectra laser.
Lumenis lasers and delivery systems are precision medical instruments. They
have undergone extensive testing and with proper handling are useful and
reliable clinical instruments. If you have questions regarding your laser or
delivery system, contact your local Lumenis representative.
WARNING - 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, including all Safety and Regulatory sections, should be carefully read
and comprehended before operation.
Characteristics of the 532-nm green laser beam
The 532-nm wavelength falls in the green region of the electromagnetic
spectrum. Laser light visible or invisible can cause tissue damage; therefore,
eye safety precautions must be taken by the physician, patient, and any
observers in the room. A low-power, visible aiming beam that is coaxial with
the treatment beam is used to target tissue.
Green light energy is readily absorbed by melanin, hemoglobin, and
oxyhemoglobin in the eye, but avoids macular xanthophyll. These
characteristics allow for effective laser photocoagulation of ocular tissue.

General Operation
Laser Preparation
The laser is shipped directly from the factory to your site. Your local Lumenis
representative initially unpacks, inspects, sets up, and installs the laser to
ensure that it is ready for use. In addition, Lumenis provides in-service
training to ensure that your surgical staff is experienced with the operation
and safety considerations of the laser.
Thereafter, you, or the nursing staff at your facility, will perform the daily
maintenance routines associated with the laser and delivery devices, including
inspecting and cleaning the laser and delivery devices; sterilizing; connecting,
and disconnecting the delivery devices; and performing a laser beam integrity
check. These procedures are detailed in this manual and in the delivery device
operator manuals.

General Operation
Laser console
The laser console houses the control screen, main power keyswitch,
emergency off button, control electronics, laser source and associated optics,
and power supply. The laser console is the central unit to which the laser
components and delivery devices attach.
Remote control (optional)
The optional remote control provides all of the necessary controls for setting
treatment parameters. It can be used in place of, or in addition to, the laser
console controls.
External door interlock plug
The external door interlock plug must be inserted into the external interlock
receptacle on the rear of the laser console for the laser to operate. The plug
comes pre-installed from the factory. The plug may be wired to an external
switch to disable the laser if the treatment room doors are opened during
treatment.
Footswitch
The footswitch activates the laser treatment beam when you depress it while
the laser is in ready mode. If you are using the Smart footswitch, the
footswitch engages the automatic eye safety filter when you place your foot
inside of the footswitch housing while the laser is in ready mode. If you are
using the PowerEase footswitch, you can adjust the laser power by pressing the
switches on the inside left (decrease power) and right (increase power) of the
footswitch housing.
Delivery devices
Delivery devices for a variety of applications may have been shipped with your
Novus Spectra laser. Refer to the operator manuals included with those
delivery devices for specific descriptions and operating instructions.
Compatible delivery devices include Acculite endoprobes, fibers, laser
integrated ophthalmoscopes (LIO), LaserLink Z and HS and integrated slit
lamps.

Using the external door interlock
The external door interlock is a safety feature that disables the laser if the
treatment room doors are opened or the interlock plug is removed.
Use of an external door interlock is optional; however, an interlock plug must
be inserted into the external door interlock receptacle whether or not you are
using an external door interlock. The laser will be inoperative unless a plug is
inserted into the receptacle. For your convience, the Novus Spectra comes
from the factory with an interlock plug pre-installed.
An external door interlock rated at 12 VDC is required for this system. When
using an external door interlock, the laser automatically disables and returns to
standby mode if the treatment door is opened or the interlock plug is removed.
The code “ILOC” will appear on the laser console display. To resume
treatment, close the treatment room door or reinsert the interlock plug, and

WARNING - To avoid possible damage to the laser, use only qualified,
compatible Lumenis delivery devices. Using other than Lumenis delivery
devices may jeopardize safe operation or damage the laser and will void your
Lumenis warranty or service contract.
WARNING - When using a fiber optic delivery device, always inspect the
fiber optic cable to ensure that it has not been kinked, punctured, fractured, or
otherwise damaged.The fiber optic cable may be damaged if stepped on, pulled,
left lying in a vulnerable position, kinked, or tightly coiled. Do not clamp the
cable with a hemostat or other instruments. If sterile tape is used, always
remove the tape before lifting the cable.A damaged fiber optic cable may cause
accidental laser exposure or injury to the treatment room personnel or
patient, and/or fire in the treatment room.
WARNING - Carefully inspect any delivery system sterile packaging to ensure
that it has not been torn or punctured. If there is any damage to the sterile
packaging, do not use the delivery system
WARNING - If an emulation plug is used, the operator shall assume all
responsibility for ensuring that the proper eye safety filters are used.
A variety of delivery devices are compatible with this laser. To connect a

Connecting eye safety filters (LaserLink, slit lamp, and Acculite only)
Installing the eye safety filter(s)
When using a LaserLink, a Lumenis slit lamp, or Acculite delivery devices,
you must install a compatible automatic eye safety filter or fixed filter onto
the slit lamp or operating microscope. The eye safety filter protects the
physician’s eyes from exposure to laser light while looking through the slit
lamp or operating microscope.
If the eye safety filter is not properly connected to the laser, an E400 error
code will display on the laser console. If the eye safety filter is not compatible,
an E401 error code will display.
Refer to the appropriate delivery device operator manual for detailed eye
safety filter installation instructions.
CAUTION - During treatment, the eye safety filter must be attached to the
slit lamp or operating microscope. Failure to use an eye safety filter could
result in ocular injury. In addition, some slit lamps and microscopes require an
auxiliary eye safety filter to protect persons observing the procedure through
an observation tube. To determine if an auxiliary eye safety filter is required,
review your slit lamp or microscope operator manual or contact the
manufacturer.
