Ultrasound device capable of precise imaging, biometry of eye
Early results from a repeatability and reproducibility study of a precision ultrasound device indicate the anterior segment imaging device can provide unique measurements on the cornea and will have multiple applications in the future.

Golden, CO-A new precision ultrasound ophthalmic device (ArcScan Insight 100, ArcScan Inc.) produces finely detailed, highly sensitive anterior segment images, according to the lead investigator at the first of several study sites.
The repeatability and reproducibility testing of the device-which received FDA 501(k) clearance as well as CE Mark approval earlier this year-is taking place in an actual practice setting.

“The quality and the detail that you see on the images is not something that I’ve seen on other imaging devices before,” said Amy Kelmenson, MD, of Colorado Ophthalmology Associates, Denver. “You can image the entire cornea from limbus to limbus in fine detail, in contrast to some devices that produce a detailed image of just a central area of the cornea.

“We’re also getting very sensitive images of the entire anterior segment, from the cornea back to the iris, the lens, and even as posterior as the posterior lens capsule,” Dr. Kelmenson said. “You can even see the lens zonules, which I don’t think I’ve ever been able to see on any other anterior segment imaging device.”

The device is relatively easy to use compared with other types of immersion ultrasound, Dr. Kelmenson observed. Technicians at the clinic required only minimal initial training to become proficient in using the device.
