| ClearScan® Probe Cover
ClearScan® is an innovative single use ultrasound probe cover which eliminates the difficulties and problems of the shell and gel system. The ClearScan® consists of an extremely thin film that is acoustically invisible, resulting in the same distortion free ultrasound image as with the shell/gel technique, but without the discomfort. The ClearScan® conical shape enables the examiner to safely scan all eye quadrants without causing a corneal abrasion. Patients are examined while sitting up and the viewing orientation is the same as through a slit lamp. To view ClearScan® video and examination tips, visit our YouTube channel. Clinical UBM images, videos, and Video script (PDF file) are also available in our library.
OVERVIEW
Ultrasonic Biomicroscopy or UBM is a useful diagnostic tool with diverse clinical applications for visualizing subtle detail in the anterior segment. When an UBM exam is combined with the ClearScan, a single-use conical shaped probe cover , the anterior segment, sclera, eye lid, as well as lachrymal anatomy are easily examined. The FDA certified ClearScan cover makes the shell and gel technique obsolete and overcomes limitations related to sterility, safety, exam procedure and patient comfort.

Enhanced imaging leads to better treatment decisions
UBM with ClearScan is essential in the glaucoma examination for imaging the angle, scleral spur, iris. structures behind the iris, such as the ciliary body, and the lens. Delineation of posterior structures are not possible with coherent light technology. Additionally, UBM with ClearScan is invaluable for sulcus-to-sulcus imaging as well as determining the presence of synechia, cysts, clefts, retinoschisis and melanomas that invaded the ciliary body.

CLEARSCAN® COVER VS. OPEN SHELL SYSTEM
Open Shell Disadvantages
• Open Shell not FDA certified
• Probe and Open Shell sterility issues
• Patient discomfort and safety
Methodology Concerns
• Patient must be in reclined position
• Ultrasound gel often required resulting in patient discomfort
• Shell placement causes patient discomfort and anxiety
• Cannot examine all eye quadrants without shell contacting the cornea
• Potential for corneal abrasions
• Corneal distortion and tenting caused by pressure applied from open shell
