GenesisPlus Operator Manual

EV C, 10/16
WARNING
The laser light produced by GenesisPlus is an invisible infrared
(1064nm) light that can cause permanent eye damage. Never look
directly into the handpiece even when wearing protective eyewear.
Never look directly into the laser beam or at scattered light from
metallic or other reflective surfaces. Both direct and reflected laser
beams may contain sufficient energy to cause permanent eye dam-
age.
All personnel operating GenesisPlus or in the vicinity of the system, including the patient, staff
personnel and observers, should wear protective eyewear with sufficient protection (optical
density or shade factor specified in System Specifications or greater) for the 1064 nm Nd:YAG
wavelength. The eyewear should have guards on both sides to protect the eyes from lateral
exposure.
WARNING
Never allow anyone without proper protective eyewear in the room
while the system is in use.
Guidelines and information on the safe use of lasers, and the safe use of lasers/laser systems in
diagnostic and therapeutic areas, can be found in the following:
• The American National Standard for the Safe Use of lasers in Health Care Facilities
(ANSI Z136.3-2005).
• The American National Standard for Safe Use of Lasers
(ANSI Z136.1-2007).
• European Standard EN 60825:2007, Appendix A.
The ANSI and the European standards describe the following terms in the description of laser
hazards:
• Maximum Permissible Exposure (MPE) - The highest level of laser radiation to
which a person may be exposed without hazardous effect or adverse biological
changes in the eye or skin.
• Nominal Ocular Hazard Distance (NOHD) - The distance along the axis of the
unobstructed beam beyond which exposure during normal operation is not expected
to exceed the appropriate MPE. This distance is measured from the laser aperture.
• Nominal Hazard Zone (NHZ) - The space within which the exposure level during
normal operation exceeds the applicable MPE. The outer limit of the NHZ is the
NOHD.
For specific values, see Eye Safety in the System Specifications section of this manual.
