This guide is intended to help you decide whether to use and how to use the TrueTear
®
device to provide a temporary increase in tear production and improvement in dry eye
symptoms. This device provides small electrical pulses to stimulate production of your

Your provider has determined that the TrueTear

device may work for you. Please read
this entire guide and discuss your questions with your provider. You can then consider
the expected benets versus the risks and make an informed decision.
Facts About Dry Eye Symptoms
Dry eye symptoms may include, but are not necessarily limited to, sensitivity to light,
grittiness, pain or soreness, blurred vision, and poor vision. Dry eye symptoms may be
caused by advanced age, contact lens wear, certain medications, eye diseases, other
medical conditions, or environmental factors. In some people, dry eye symptoms may
be improved by increasing the amount of tears produced.
