VISULAS green 2.6 Hazard due to coherent laser radiation
18 / 116 000000-2096-101-DokS-GB-181218
The responsible organization is responsible for providing proper
laser safety goggles. The safety goggles must be approved for the
wavelength of the laser and for the type and intensity of the laser
radiation in your country.
Laser safety goggles for VISULAS green: 532 D LB5
2.6.5 Patient safety
The key parameter in laser treatment is the energy density (laser
fluence) at the target, i.e. applied laser energy divided by the area
of the laser spot. In order to achieve a consistent physiological
effect, the power / energy should therefore be adjusted when the
spot diameter is changed.
The energy density (laser fluence) is always displayed on the user
interface of the VISULAS green. Following a change in contact lens
or spot diameter, ensure that the value for energy density is the
same as prior to the change.
The power or energy level on the VISULAS green can be varied.
If, after using an applicator (e.g. LIO VISULAS green), you change
to a different applicator (e.g. slit lamp), the correct applicator must
be selected from the main menu.
Never start treatment if a different applicator is shown in the
display to the one required, or if no physician's safety filter is fitted.
Do not fire the laser beam if the tip of the laser endoprobe is
touching the tissue.
2.6.6 Danger caused by direct irradiation and reflection
The system and its applicators emit visible laser radiation which is
dangerous to the human eye and skin.
As an application device the LIO VISULAS green laser indirect
ophthalmoscope may only be operated together with the
VISULAS green laser console and not with 532 nm lasers of third
party suppliers.
Strictly avoid irradiation of the eye or skin by direct or scattered
radiation. Metallic and similar surfaces reflect laser beams.
All persons present in the laser hazard area must wear protective
goggles as a precaution against unintentional direct or reflected
radiation.
Remove any bright, reflecting objects from the laser range or cover
them. Also cover windows and reflecting walls with non-
combustible cloths.
Take safety precautions if there is a risk of noxious gases, dust and
vapors, secondary radiation or explosive gas mixtures from
materials exposed to laser radiation within the laser hazard area.
Only use medical instruments in the laser beam path which are
shaped or surface-finished to prevent hazardous reflection.
