System Description
3.1. Introduction
The Smart532-nm green laser system is indicated for ophthalmic
applications; ear, nose and throat applications; dentistry and dermatologic
applications. Complete and detailed lists of the system's clinical
indications appear in Appendix A of this manual – Clinical Guide.
Lumenis’ complete line of delivery systems and accessories further
extends the versatility of the Smart532 laser system.
Lumenis lasers and delivery systems are precision medical instruments.
They have undergone extensive testing and with proper handling are useful
and reliable clinical instruments. If you have questions regarding your laser
or delivery system, contact your Lumenis representative.
Lasers generate a highly concentrated energy beam that may
cause injury if improperly used. To protect the patient and the
operating personnel, the entire laser and the appropriate delivery
system operator manuals, including all Safety and Regulatory
sections, should be carefully read and comprehended before
operation.
3.1.1. Characteristics of
the 532-nm Green
Laser Beam
The 532-nm wavelength falls in the green region of the electromagnetic
spectrum. Visible or invisible laser energy can cause tissue damage;
therefore, eye safety precautions must be taken by the physician, patient,
and any observers in the room. A low-power, visible aiming beam that is
coaxial with the treatment beam is used to target tissue.
Green light energy is readily absorbed by melanin, hemoglobin, and
oxyhemoglobin in the eye, but avoids macular xanthophyll. These
characteristics allow for effective laser photocoagulation of ocular tissue.
