Safety          xi
The probability that a person without eyewear will directly view a fiber 
breaking is low, but can occur.  The probability of the fiber breaking while 
actually aimed at someone's eye is low.  The following factors must all occur 
simultaneously in order to result in hazardous exposure: 
 
• 
• 
• 
• 
• 
• 
• 
Alignment of the laser beam with the eye 
Close proximity of the eye to the source of the laser light 
Exposure time in excess of damage threshold 
 
With proper use of the laser equipment, the chance of these events occurring 
simultaneously is remote, but may occur.  Laserscope supports the ANSI 
recommendation that all personnel in the operating room wear appropriate 
eyewear when the laser is being used for open or endoscopic procedures. 
 
6.  Do I need laser eyewear with endoscopic cases? 
 
Yes, protective eyewear is routinely required for most laser cases.  In an 
editorial article published by Rockwell Laser Industries, the use of eye 
protection during endoscopic laser surgery was addressed.  According to 
Rockwell’s interpretation of ANSI Z136.1 (Section 4.3.6.2), Class 1 conditions 
shall be considered as fulfilled for those limited open beam path lasers or 
laser systems where measurements and analysis confirm that the accessible 
levels during operation are at or below applicable maximum permissible 
exposure (MPE) levels.  By this definition, endoscopic laser surgery (ruling 
out the possibility of a broken fiber) could be considered a Class 1 condition. 
 
Laserscope supports the ANSI and AORN recommendations that 
protective eyewear be available and worn during all laser procedures 
by all personnel present. 
 
7.  What are some appropriate ways to protect the patient’s eyes 
during laser surgery? 
 
The patient should always be educated on the laser procedure and eye 
protection requirements prior to the start of the procedure. 
 
In addition, the following protective measures should be taken: 
Use moist towels where appropriate. 
If the patient is awake, use suitable protective eyewear, and instruct 
the patient not to remove the eyewear. 
If the patient is anesthetized, lubricate and tape the patient’s eyelids 
shut. 
Use a combination of moist towels, gauze eye pads, eyeshields, and 
drapes to protect the eyes when the surgical site is on or near the face.
