ANSI Z136.3-2018

Safe Use of Lasers in Health Care

This standard provides guidance for the safe use of lasers in health care. As defined herein, laser radiation refers to the ultraviolet, visible, and infrared regions of the electromagnetic spectrum. Laser radiation should not be confused with ionizing radiation or light from other sources.



IEC 60601-2-22 Ed. 4.0 b:2019

Medical electrical equipment - Part 2-22: Particular requirements for basic safety and essential performance of surgical, cosmetic, therapeutic and diagnostic laser equipment

IEC 60601-2-22:2019 is available as IEC 60601-2-22:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60601-2-22:2019 applies to the Basic Safety and Essential Performance of laser equipment for surgical, therapeutic, medical diagnostic, cosmetic or veterinary applications, intended for use on humans or animals, classified as Laser Product of Class 1C where the Enclosed Laser is of Class 3B or 4, or Class 3B, or Class 4. Medical Electrical Equipment or Medical Electrical Systems which incorporate lasers as sources of energy being transferred to the Patient or animal and where the lasers are specified as above, are referred to as “laser equipment” in this document. Laser Products for these applications classified as a Class 1, Class 1M, Class 2, Class 2M or Class 3R Laser Product, are covered by IEC 60825-1:2014 and by the general standard. If a clause or subclause is specifically intended to be applicable to ME Equipment only, or to ME Systems only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies to ME Equipment and to ME Systems, as relevant. Hazards inherent in the intended physiological function of laser equipment within the scope of this document are not covered by specific requirements in this document except in 7.2.13, Physiological effects, of the general standard. If the laser equipment is Class 1C according to IEC 60825-1:2014 and is used as a laser appliance in a household, it is covered by IEC 60335-2-113:2016. This fourth edition cancels and replaces the third edition published in 2007 and Amendment 1:2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
 a) it takes account of IEC 60601-1:2005/AMD1:2012 and IEC 60825-1:2014, which have been published since publication of the third edition;
 b) it addresses technical and safety issues which have arisen since publication of the third edition;
 c) the scope of this fourth edition differs from the scope of the third edition. It now includes Class 1C laser equipment, as defined in IEC 60825-1:2014, when the Enclosed Laser is Class 3B or 4;
 d) LED (light emitting diode) products are now excluded from this document as medical LED products may be covered by IEC 60601-2-57.


IEC 60601-2-57 Ed. 1.0 b:2011

"Medical electrical equipment - Part 2-57: Particular requirements for the basic safety and essential performance of non-laser light source equipment intended for therapeutic, diagnostic, monitoring and cosmetic/aesthetic use"

"IEC 60601-2-57:2011 applies to basic safety and essential performance of equipment incorporating one or more sources of optical radiation in the wavelength range 200 nm to 3 000 nm, with the exception of laser radiation, and intended to create non-visual photo-biological effects in humans or animals for therapeutic, diagnostic, monitoring, cosmetic/aesthetic or veterinary applications; hereafter referred to as light source equipment. IEC 60601-2-57:2011 does not apply to equipment for sun tanning, for ophthalmic instruments or for infant phototherapy. Light source equipment may consist of a single or multiple sources of optical radiation, with or without power supply, or may be incorporated into a complex system that includes optical, electricalor mechanical systems or sources of other radiation."


ANSI Z80.11-2012 (R2017)

Ophthalmics - Laser Systems for Corneal Reshaping

This standard applies to any laser system whose primary intended use is to alter the shape of the cornea through the removal of corneal tissue, resulting in the improvement of visual performance. This standard addresses the vocabulary, performance requirements, labeling, and clinical investigations necessary for this type of device.
