iTear100 Neuro-Stimulation Device FAQs
What Is the iTear100 Device?
This section explains the basics of the iTear100, including how it works and who it can help. Understanding the device can help you decide if it is a good option for your needs.
The iTear100 delivers mild electrical stimulation to the side of your nose, activating the external nasal nerve. This triggers a natural reflex that connects to your tear glands, prompting them to produce your own tears within about 30 seconds. Because it enhances the body’s own tear production, many patients find the results more effective and longer-lasting than artificial tears.
People with dry eye disease who struggle with constant dryness, burning, or irritation often see improvements with the iTear100. It may help those whose dry eyes are related to aging, extensive screen use, or health conditions such as Sjögren’s syndrome. It is also a useful option for people who are sensitive to the preservatives found in many eye drops.
Unlike artificial tears that add temporary lubrication, the iTear100 stimulates natural tear production from within. This offers several unique advantages:
- It stimulates your body’s own tears for longer-lasting relief.
- It helps create a more balanced tear film, which eye drops cannot replicate.
- It reduces the need for frequent application of drops throughout the day.
- It is free of preservatives that can irritate sensitive eyes.
Using the iTear100 Safely
Learning the proper way to use the device helps ensure you receive the best results while avoiding unnecessary discomfort. This section explains how to use the device and what to expect.
First, charge the iTear100 fully, which typically takes about an hour. Gently place the tip against the side of your nose and press the button to start a 30-second stimulation cycle. A mild tingling sensation is normal and should not be painful. The device can be used a few times per day as recommended by your doctor.
The iTear100 is FDA-cleared and has undergone safety testing. Most patients tolerate it well, with the most common side effects being brief tingling, slight nasal discomfort, or a short-lived runny nose. These effects typically resolve quickly on their own.
While safe for most adults, you should consult your doctor before using the device if you have:
- An implanted electrical device, such as a pacemaker or defibrillator.
- Had recent nasal surgery or have an acute facial or nasal infection.
- An active skin condition around the bridge of your nose.
- A severe neurological disorder that affects your facial nerves.
