Changing technologies: Unchanging concerns

Abstract

The use of lasers in medicine has been developing gradually since the 1950’s. Although the technology has continued to develop, the well known hazards of eye and skin injury still remain primary concerns. This paper will discuss the recent findings of a national survey regarding the issues of most concern to medical laser safety officers, as well as, discussion of specific incidents regarding patient and personnel injury during the delivery of laser therapy. Although the risks of significant eye injury from laser beams are well documented and understood, the lack of, or inappropriate use of eye wear remains a significant factor in reported laser accidents. The most significant optic injuries are damage to cornea and retina from specific laser beams, however, it has been documented that intermittently pulsed, visible wavelength lasers may also pose hazards associated with photo stimulation. Safety officers report difficulty in securing compliance with the requirements regarding the use of eye wear. Additionally, concerns center around the potential for serious fires, and the lack of education on the part of responsible people regarding appropriate safety mechanisms. Initially, almost all laser surgery was done in the hospital and operating room setting, which is a highly controlled environment subject to significant regulation. Today, an increasing number of laser procedures are being done in outpatient, and office settings. Regardless of the location of the laser, the hazards, and requirements remain the same. While we have become very comfortable with the use of the laser, personnel in all areas must be well educated. To maintain a safe laser environment, we cannot become complacent about the utilization of appropriate safety mechanisms.The use of lasers in medicine has been developing gradually since the 1950’s.
