Escalon Medical Corp. operates in the healthcare market, specializing in the development, manufacture, marketing and distribution of medical devices for ophthalmic applications. The Company's A-Scan provides information about the internal structure of the eye by sending a beam of ultrasound along a fixed axis through the eye and displaying the various echoes reflected from the surfaces intersected by the beam. Its B-Scan is primarily a diagnostic tool that supplies information to physicians where the media within the eye are cloudy or opaque. Its UBM is a high-frequency/high-resolution ultrasound device, designed to provide information about the anterior segment of the eye. The Company's pachymeter measures the thickness of the cornea. It distributes two intraocular gas products C3F8 and SF6, which are used by vitreoretinal surgeons as a temporary tamponade in detached retina surgery. The Company also provides surgical packs and AXIS image management system software.
