It is well established that exposure of the eye to intense light
sources for extended periods of time poses a risk of retinal photic
injury. Many ophthalmic instruments illuminate the eye with
intense light. The light levels on the Pulsair have been set at the
lowest level possible.
No visible retinal lesions have been identified as a result of using
Pulsair tonometers, however, young children and persons with
diseased eyes may be at a higher risk. The risk may also be slightly
increased if the person being examined has had any exposure
with the same instrument or an other ophthalmic instrument
using an intense visible light source during the previous 24 hours.
This will apply particularly if the eye has been subjected to retinal
photography.
