The protective eyewear the technician had chosen provided protection at 532 nm but not for the upshifted NIR line and produced a retinal burn. In this event a laser company installer was electrocuted while installing a copper vapor laser. A interlocked protective panel had been manually bypassed during the installation to make adjustments. Then, after several minutes, as is common with severe electrical shock, he expired. A person experienced in CPR was unable to bring him back.
Serviceman receives accidental retinal exposure from argon laser.
A field service engineer was working on an argon laser photo-coagulator. The person received an intrabeam ocular exposure causing a permanent retinal lesion. The beam reflection from a target paper went into eye causing a bright afterimage lasting 20 minutes which led to a permanent central retinal burn. Such an incident strongly suggests a need for information and education regarding the limitations regarding the safety equipment used with lasers. An attending nurse was temporarily blinded by a reflected beam from a retinal photocoagulator when the beam was reflected from a piece of the equipment.
