Master Eye Associates Continues to Lead the Way with the most accurate testing method in the world for intraocular pressure.
When intraocular pressure is the only thing possible for eye doctors to treat and the only thing we can control in glaucoma, don’t you think the measurement should be accurate?
Accurate measurement of intraocular pressure (IOP) is absolutely critically important in the diagnosis and management of glaucoma. It is widely recognized that current methods of measuring the fluid pressure inside the eye, intraocular pressure (IOP), are very often inaccurate, inconsistent and not repeatable - except the Reichert 7CR used by Master Eye Associates. The current standard methods are highly dependent on operator judgment and this subjectivity is one of the sources of the inaccurate pressure measurements. In addition to operator error and subjective judgment, the thickness of the cornea and the rigidity of the corneal structure complete the list that really makes the measurement of intraocular pressure inaccurate. Corneas that are thicker than average show pressures much higher than if the cornea was thinner and vice-versa corneas that are thinner than average measure much lower pressures than what the pressure really is inside the eye.
“ Correction nomograms that adjust Goldman Applanation Tonometry IOP based solely on central corneal thickness CCT are neither valid nor useful in individual patients.”

The Only True and Accurate Glaucoma Pressure Measuring Instrument is Available at Master Eye Associates
The Reichert 7CR from Reichert Technologies utilizes a patented bi-directional applanation process to characterize the biomechanical properties of the cornea and reduce their impact on the IOP measurement. This new advanced technology provides a new measurement which is referred to as Corneal Compensated IOP. It is minimally affected by corneal visco-elastic properties, thickness, or surgical procedures such as LASIK or PRK. Therefore, Corneal Compensated IOP is a better indicator of glaucoma than other methods of tonometry, including Goldmann Applanation tonometry.
The Reichert 7CR is more accurate in all patients, including:
• Low or normal pressure glaucoma patients
• Primary Open Angle Glaucoma patients
• Post-LASIK and Post-PRK refractive surgery patients
• Patients with Fuchs’ Corneal Dystrophy or Corneal Edema
• Keratoconus or corneal ectasia patients
• Patients with thick, thin, or otherwise biomechanically atypical corneas
Reliable Intraocular Pressure Measurements are Guaranteed
The Reichert 7CR employs an advanced signal-scoring feature that helps ensure the accuracy and reliability of measurement results. A score for each measurement is displayed on the screen. Scores below a certain threshold are indicated as unreliable.
The Most Advanced Intraocular Pressure Test is Available at Master Eye Associates
The Reichert 7CR utilizes a collimated air-jet to depress the front of the cornea and an electro-optical system to monitor the applanation process. This method results in a quick and painless measurement that is most of all very, very accurate. Additionally the process is non-contact so no anesthesia is required and there is no chance of contamination or spreading of infection.
Instead of a subjective pressing of a probe onto the cornea surface to achieve applanation (pressure on the cornea), the Reichert 7CR applanation detection system monitors the change in corneal curvature in real time, recording 400 data samples during the 25 millisecond measurement process! This unique feature ensures that the appropriate applanation force is automatically delivered to each eye being measured. Unlike all other methods, it is consistent, repeatable and accurate.
