6.2 General Warnings
Doctors should ensure they have extended training before attempting to carry out
any of the indicated procedures. Doctors will take full responsibility for the setting
of the Laser unit operating characteristics, techniques and methods used during
treatment. They must use their own clinical judgment in determining all aspects of
the treatment carried out.
For all type of Delivery units always ensure that the power levels are not set too high
at initially.
Always set the power levels according to the tissue effects. Remember that highly
vascularized and pigmented tissue will require less power than lightly pigmented.
The Aiming beam and Green laser beams are coaxial and if there is any distortion to
one of them then the other may also be distorted and this can lead to inconsistent
tissue effects and clinically unsatisfactory results.
By reducing the spot size by half will increase the power density by a factor of four
so be very careful not to deliver too much power to the site.
If the delivery of the Laser does not produce satisfactory tissue effect then increase
the pulse duration first then the power level. The aim is to produce a grey-white burn.
Any assistant personnel in the treatment room should always wear appropriate laser
safety glasses suitable for this particular laser wavelength while the Laser unit is in
use.
Outside the treatment room should be placed Laser warning signs or any
appropriate warning signs for the country the Laser is being used in. Generally the
warning signs should state minimum as: “Danger/ Caution Laser Radiation, avoid eye
or skin exposure to direct or scattered laser radiation.”
The laser can coagulate blood vessels up to 1.5mm in diameter. For larger diameter
vessels coagulation may be difficult so other means such as electrocautery may be
needed.
When treating a patient’s eye, ensure that untreated eye should cover with
protective shield from the unwanted laser reflection that can lead to irreversible eye
damage.
Avoid directly firing the Laser onto the flammable liquids or gases
Avoid any wet condition near console or footswitch although footswitch is rated
IPX8 but still not recommend use in the wet condition to avoid the electrical hazards.
Any precaution measured should be taken during any surgical process. All
personnel should always wear the protective gears such as, gown, cap, mask, latex
gloves, and safety goggles.
