VISULAS green 2.6 Hazard due to coherent laser radiation
000000-2096-101-DokS-GB-181218 17 / 116
2.6.3 Laser hazard area
The laser hazard area should be as small as possible and demar-
cated by suitable screens. Unauthorized persons should be
prevented from entering the laser hazard area. The number of
persons in the laser hazard area must be kept to a minimum.
Where suitable screens are not in use, the entire treatment room
must be considered as a laser hazard area.
A laser warning lamp must be installed at the entrance door
indicating when the laser is in operation.
The ZEISS laser warning lamp should preferably be used. The
supplied remote door interlock switches the laser off automatically
when the door to the laser area is opened to gain access. If a laser
warning light from a third-party supplier is used, the door interlock
may only be used in conjunction with the door contact isolator. The
laser hazard area must be clearly demarcated and marked as such
during the entire laser operation. Other safety precautions should
be clarified with local authorities or with your laser safety officer.
Only the patient and appropriately trained personnel may remain
within the laser hazard area. These persons must wear suitable
laser safety goggles when the laser is in operation.
Persons working in the laser hazard area must be given instruction
concerning safety regulations, safety precautions and operation of
the system at least once a year. Keep a written record of these
instructions, listing the participants.
All objects within the laser hazard area, including the floor, should
have diffusely reflecting surfaces or be covered with diffusely
reflecting material.
2.6.4 Laser safety goggles / eye patches
All persons present in the laser hazard area during the laser
operation must wear laser safety goggles.
The laser hazard area is the area in which the maximum permissible
exposure (MPE) may be exceeded. This includes areas into which
the laser beam may unintentionally be deflected by a reflecting
surface.
The patient's eye which is not being treated must also be properly
protected.
When using a monocular assistant's scope, the second eye must be
covered by an eye patch during laser treatment.
Exception: The physician does not require laser safety goggles
when observing the target area through
• a surgical microscope equipped with a 532 nm physician's
safety filter
• a ZEISS laser slit lamp or
• the LIO VISULAS green laser indirect ophthalmoscope.
