Kowa FM-600 Laser Flare Meter

The Kowa FM-600 Laser Flare Meter provides quantitative, reproducible measurements of aqueous flare to support the clinical assessment and monitoring of ocular inflammation.

The instrument performs a non-contact, non-invasive and painless in-vivo measurement. A 635 nm diode laser scans a measurement window projected within the anterior chamber. Light scattered by proteins and other particles is detected by a photomultiplier tube and expressed numerically in photon counts per millisecond.

Unlike subjective grading methods, the FM-600 supplies objective numerical results that can help clinicians document changes and compare measurements during follow-up. It is particularly useful when evaluating uveitis, postoperative inflammation following intraocular-lens implantation and other conditions associated with increased aqueous flare.

Each measurement requires approximately 0.5 seconds. Front-view and side-view alignment modes help the operator position the measurement area accurately, while small-pupil mode supports examinations in patients with restricted pupil size.

The compact console incorporates a 5.6-inch color LCD monitor, an integrated calibrator and a 58 mm thermal printer for immediate documentation of results and graphs. Controls are positioned within the operator’s reach to facilitate a smooth workflow while facing the patient.
