User-friendly, patient-friendly,
designed to be the best partner.

Non-contact, non-invasive, non-pain, in-vivo, all is possible with this one-compact Kowa FM-600 especially elaborated for quantitative measurement of aqueous flare.
This measurement is known as being useful in follow-up observation of flare for patients with uveitis,after IOL implantation.
Designed to operate faster, to conduct easier and better, the Kowa FM-600 reflects what is efficient and accurate compactness.



Position the alignment luminous dot in the center circle while bringing the dot into focus. Then shift to the oblique alignment by pressing on the joystick button. Measurement is possible when the measurement window at the center is green.

Measurement results


The scattered light converted into electrical signal and its intensity is displayed as flare value on the LCD monitor.

Measurement Principle


The Kowa FM-600 is based on the measurement principle of laser light scattering detection. The instrument uses a diode laser beam to scan a measurement window that is projected inside the anterior chamber of the eye. As an aqueous protein (component of inflammation) passes through the focal point of the laser, light scattering occurs. The intensity of the scattered light (directly proportional to the amount of protein particlesflare) is detected by a photo-multiplier (PMT), which generates an electrical signal. These signals are immediately digitized to eliminate outside noise interference and are processed by a computer that displays for user analysis. The unit of measurement employed by the FM-600 is photon counts per millisecond (pc/ms).
