Ophthalmic instruments: an assessment of radiation emissions and potential hazards
This report discusses the following: the optical radiation emitted by a variety of ophthalmic instruments were measured and compared to current safety standards. In addition, a survey of clinical diagnostic examination times was conducted to compare exposure safe times to visible lesion threshold. It was demonstrated that excessive levels of ultraviolet (UV) and infrared (IR) radiation could be emitted and should be eliminated. Several of the instruments emitted levels of visible radiation that resulted in very short safe times and could exceed the visible lesion threshold. Four experiments demonstrated instrument operating conditions that would reduce the potential for ocular hazards from ophthalmic instruments.
