What is TrueTear®
TrueTear® is the first of its kind in eye care. TrueTear® provides a temporary increase in tear production during neurostimulation in adult patients.
The neurostimulation approach with TrueTear™ is a proven technology that is used in well know devices like pacemakers, cochlear implants and TENS Devices for chronic back pain. TrueTear™ is the first and only neurostimulation device for the treatment of Dry Eye Disease and is FDA approved to safely stimulate the nerves that supply the Lacrimal Function Unit (LFU); which is the part of your eyes that supplies the natural, healthy tears that keeps our eyes moist, comfortable and clear. The LFU is very complex, with multiple components and parts that can become damaged and breakdown in the Dry Eye Disease cycle. Past Dry Eye treatments usually focus on helping one or a few of the damaged parts only, but TrueTear™ has the ability to help the entire LFU naturally. It does this in a drug free way that basically turns your eyes natural tear system back on.
With TrueTear®, tearing can occur within seconds, however it can take a shorter or longer time depending on the patient. The effect is temporary, but patients can use TrueTear® at least twice a day, as needed. The device may be used for up to 30 minutes per 24 hour period. It can fit right into patient’s daily routine.
