    Clinical Applications of the Ocular Response Analyzer:

    Cornea
    The Ocular Response Analyzer enables clinicians to assess the cornea based on biomechanical tissue properties, rather than geometry only. It has been demonstrated that Corneal Hysteresis (CH) and Corneal Resistance Factor (CRF) measurements are significantly lower in keratoconus patients. Furthermore, CH and CRF are significantly reduced following refractive surgery as a result of complex biomechanical changes. CH and CRF provide a more complete characterization of corneal properties than CCT and topography alone, making these metrics useful in the pre-operative assessment of refractive surgery candidates.

    What is Corneal Hysteresis?

    Corneal Hysteresis (CH) is the difference in the inward and outward pressure values obtained during the dynamic bi-directional applanation process employed by the Ocular Response Analyzer, as a result of viscous damping in the cornea. It is a characterization of the cornea?s energy absorption capacity, which is a function of the biomechanical properties of the cornea.

    Ocular Response Analyzer is the only instrument in the world capable of measuring corneal biomechanical properties and Corneal Compensated IOP.

    How it works

    The Ocular Response Analyzer utilizes a dynamic bi-directional applanation process to measure biomechanical properties of the cornea and the intraocular pressure of the eye. A precisely metered collimated air-pulse causes the cornea to move inwards, past applanation, and into a slight concavity. Milliseconds after applanation, as the air pulse force decreases, the cornea begins to return to its normal configuration. In the process, it once again passes through an applanated state.

    An electro-optical system monitors the curvature of the cornea throughout the deformation process taking 400 data samples during the 20-millisecond measurement. Two independent pressure values are derived from the inward and outward applanation events. Viscous damping in the cornea results in an offset between the inward and outward pressure values. The difference between these two pressure values is Corneal Hysteresis (CH).

     

    Comprehensive Pressure and Cornea Information

    IOPcc (Corneal Compensated IOP) - New IOP measurement less affected by corneal properties.

    CH (Corneal Hysteresis) - Measure of viscous damping in the cornea, providing new indicators for disease diagnosis and management.

    CRF (Corneal Resistance Factor) - Total visco-elastic response of the cornea.

    IOPg (Goldmann Correlated IOP) - Traditional IOP measurement for historical reference.
