OBJECTIVE Tissue injuries caused by the thermal effects of xenon light microscopes have previously been reported. Due to this, the development of a safe microscope light source became a necessity. A newly developed laser light source is evaluated regarding its effectiveness and safety as an alternative to conventional xenon light source. METHODS We developed and tested a new laser light sourc...
Summary: The combination of 1320-nm laser lipolysis with lipoaspiration was observed to improve the appearance and contour of the infrachin neck, doubling the improvement seen with prior lipoaspiration performed by identical technique but without the addition of laser lipolysis. This is a preliminary report as to safety of the use of 1320-nm laser lipolysis. No adverse effects were observed in ...
Laser safety requirements in the U.S. are usually centered on specific Federal Government and voluntary standards such as: ~1! The Laser Product Performance Standard of the Center for Devices and Radiological Health ~21CFR 1040.10 and 1040.11!, ~2! the American National Standards Institute ~ANSI Z136 Series!, ~3! the Occupational Safety and Health Administration ~OSHA!, ~4! the Federal Aviation...
he focus of this article is a multidisciplinary research program that addresses corneal injury from exposure to infrared laser radiation. Our general methodology combines experimental physical and biological measurements with theoretical analyses to understand corneal damage. Damage thresholds are determined under carefully controlled exposure conditions, and mathematical damage models are deve...
