Patient safety
The key parameter in laser treatment is the energy density at the target, i.e.
applied laser energy divided by the area of the laser spot.
On the VISULAS YAG III Combi, the energy of the laser pulse can be pre-set.
The most important parameter in laser treatment when operated in
combination mode (VISULAS YAG III Combi and VISULAS Trion Combi) is the
energy flux density at the target area, i.e. the applied laser power divided by
the area of the laser spot. In order to achieve a consistent physiological
effect, the power should therefore be adjusted when the spot diameter is
changed.
In combination mode, the power output (VISULAS 532s, VISULAS Trion
mode) or the energy (VISULAS YAG III mode) can be pre-set.
WARNING - RISK OF LASER RADIATION
If, after using an applicator (e.g. indirect ophthalmoscope), 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.
Explosion and fire hazards
WARNING - FIRE HAZARD
Do not use the laser in conjunction with flammable anesthetics.
Keep potentially explosive materials away from the laser hazard zone. Easily
flammable materials may start fires.
A laser beam can set fire to many explosive or flammable gases or liquids,
including some of the solutions used in the preparation of surgical
procedures.
Flammable drapes, surgical gowns, gauze and other ignitable materials
must be kept out of the beam path. We recommend using non-flammable
materials and instruments and wearing gowns and clothing which do not
easily catch fire.
A fire extinguisher should be kept in the vicinity of the laser device.
Check the integrity of all lenses and glass surfaces before each use.
Significant contamination or detached coatings can lead to exposure to
hazardous radiation.
