temporarily clouded vision, retinal lesions, long-term scotoma (vision absence in an
isolated area), long-term photophobia (sensitivity to light) and/or loss of vision.
The laser aperture of the GentleYAG Laser System is at the distal end of the
handpiece. The beam enlarges as distance from the handpiece increases. The
Nominal Ocular Hazard Distance (NOHD) is the distance at which the beam is so big
it is no longer dangerous to the unprotected eye. This distance along with the full
angle beam divergence for each handpiece is shown in the following table.
To avoid vision hazards, everyone within the NOHD (see Table 2-1) of the
GentleYAG Laser System must wear appropriate eye protection. Protective eyewear
is supplied with each laser, and is available from a variety of vendors including
Candela.
