How It Works

Third Eye® Retroscope® is passed through the working channel of the standard colonoscope until it extends beyond its distal tip. As it emerges, the device automatically turns around 180 degrees to aim back toward the tip of the colonoscope and the endoscopist locks it into place.

Then, as the colonoscope is withdrawn from the colon, the Third Eye comes along with it, providing a continuous retrograde view to complement the forward view of the colonoscope. When a lesion has been detected in the retrograde view, quick and easy removal of the Third Eye Retroscope frees up the working channel for polypectomy snare or biopsy forcep.
