OCULAR RESPONSE ANALYZER FOR MEASUREMENT OF CORNEAL HYSTERESIS
Corneal Hysteresis (CH) is an assessment of the cornea’s ability to absorb and dissipate energy and has been shown to be independently predictive of visual field progression in glaucoma. Different from thickness or topography, which are geometrical attributes, Corneal Hysteresis is a tissue property.
A confident glaucoma risk assessment can be made with Corneal Hysteresis. Only Ocular Response Analyzer® G3 measuresCorneal Hysteresis and Corneal Compensated IOP (IOPcc) using patented technology to assess the unique corneal biomechanical properties of your patient. Corneal Hysteresis has shown to be an independent risk factor and more predictive of glaucoma development and progression than CCT or IOP. Using biomechanics, IOPcc is less influenced by corneal properties than Goldmann applanation tonometry. Clinical research shows compelling evidence that CH is a powerful asset for assessing patients at high risk for developing glaucoma and disease progression. CH is an important factor in determining the risk of disease progression not only in open angle glaucoma but also in normotensive glaucoma.
IOPcc given below is an important measure of true intraocular pressure in the post refractive surgery population as it is unaffected by changes in corneal thickness.
