Make a more confident glaucoma risk assessment, with Corneal Hysteresis. Ocular Response Analyzer®(ORA) is the only tonometer that measures Corneal Hysteresis (CH), a superior predictor of glaucoma progression. Effective January 1, 2015, CPT® Code 92145, was published specifically for the Corneal Hysteresis measurement provided by Ocular Response Analyzer.

Glaucoma

The Ocular Hypertension Treatment Study (OHTS), and similar studies, have brought to light the relevance of corneal thickness in glaucoma. Numerous studies utilizing the Ocular Response Analyzer have confirmed the importance of the cornea in glaucoma decision making, demonstrating that the CH measurement is of even greater significance than CCT. Studies have proven that low CH is independently associated with glaucoma progression. As such, the CH measurement gives clinicians a new tool to help identify risk of glaucoma progression and to determine which patients may need to be treated more aggressively. The CH measurement has also been shown to be predictive of IOP response to medical therapy, making the CH measurement valuable in setting treatment goals and expectations.

Intraocular Pressure (IOP)

It is widely accepted that the measurement errors in Goldmann tonometry are due to the influence of corneal properties. However it has been determined that mathematical correction of IOP, by means of CCT adjustment algorithms, is invalid and this approach is not useful in individual patients. Quite simply, the thickness of the cornea is not a surrogate for its mechanical bending characteristics.

Ocular Response Analyzer’s Corneal-Compensated Intraocular Pressure (IOPcc) takes biomechanical properties into consideration. IOPcc has been shown to be less dependent on corneal properties than other methods of tonometry and more associated with glaucoma status. The instrument?s unique ability to simultaneously provide a Goldmann-correlated IOP measurement (IOPG) and IOPcc provides clinicians with a better understanding of patient tonometry values.

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.

Intraocular pressure (IOP) is the only modifiable risk factor for glaucoma, and as such, accurate tonometry is of critical importance in the diagnosis and management of this eye disease. It’s widely recognized that the current gold standard for measuring pressure, the Goldmann Applanation Tonometer (GAT), has considerable flaws. The Goldmann, and other current tonometers, are significantly influenced by corneal properties such as rigidity and thickness. Though it has been shown that GAT provides clinically reliable measurements in the average cornea, we now know that many corneas vary more significantly form average than previously thought.

Numerous studies have shown that thicker conreas overstate intraocular pressure values, while thinner corneas understate IOP. However, thickness does not adequately describe corneal biomechanical properties, making the use of CCT-based correction algorithms questionable at best. In fact, researchers have concluded that correcting IOP based on CCT can lead not only to errors in the magnatude, but also in the direction of the adjustment:

  Touch screen alignment system
  The 5.7 inch coloured touch screen is used as operating monitor as well as for displaying all measured values. You can even move the unit in all directions by simply touching the screen. All commands can be done via touch screen.Cornea thickness related IOP
  You can easily adjust the measured IOP data according to the central corneal thickness.
  The calculation formula used by the FT-1000 is individually adjustable to your own preference.Auto Alignment + Auto Shot
  The handling of the FT1000 is very easy ? it does almost everything by itself.
  Alignment and measurement are done automatically. You just roughly align the system towards the patient eye and the rest is taken care of by the instrument. With a tip on the screen the system automatically moves to the left or right eye.

  Soft and silent air pulse
  For the comfort of your patient the FT 1000 is designed to use a very soft air pulse. Even the noise generated by the system is reduced to the minimum.
  This relaxes your patient and ensures highly accurate results.

  High Speed Measurement
  If you choose the multi shot option the system produces up to three air pulses in an extremely short sequence (0.1 seconds each).
