Eye pressure tonometer Easyton

Product Description

Easyton is a unique blend of technology and science. By its very nature, it is a tonometer for eye pressure measurement that relies on the transpalpebral method to provide as accurate results as those of intracameral IOP tonometry. This device is designed for ophthalmologists to be used in healthcare settings to encourage improvement in the diagnosis, monitoring, and treatment of glaucoma and other ocular conditions.

The effectiveness of Easyton is backed up by many accuracy, reproducibility, and repeatability tests. It has also been proven to deliver next-level diagnostics performance in the study with the Goldmann method as a reference standard. We take pride in offering this eye tonometer for sale to help eye care specialists feel the difference in IOP measurement. It can be done easier with the guaranteed accuracy when this device is at hand.

Operating principle of the Easyton tonometer for eye pressure measurement

The functionality of Easyton and the way it works cater to the needs of ophthalmologists as well as patients. Designed to simplify the process of eye pressure diagnostics and make it less stressful for people, the device is based on the vibrational operating principle. It helps minimize fluctuations and irregularities that often come with other IOP measurement methods.

Once the Easyton tonometer for eye pressure diagnostics is applied, it starts producing multiple vibrations at different frequency levels (depending on how high or low the measured IOP is). The process begins as soon as you turn on the device and place the rod on the patient’s eyelid. Easyton then automatically processes pressure readings and recalculates them into millimeters of mercury (mmHg) so that you can see the average IOP value on its display screen.

Easyton produces approximately 100 vibrations with a single push of the rod. Most of them are aimed at preventing the corneal thickness factor from affecting the results. By making up for the possible ambiguity of measurements, these vibrations are pivotal to ensure pinpoint accuracy of the IOP value.

Key benefits of the Easyton eye care tonometer

As evidenced by a variety of trials, Easyton is superior to other tonometry options. Here is what makes it your top choice:

  • more extensive applicability range than that of traditional methods;
  • careful measurement of intraocular pressure (IOP) with the tonometer, which is less affected by the corneal thickness factor;
  • 100 vibrations per second in its measuring capabilities;
  • the best device for cases when corneal tonometry is not a viable option;
  • simplified diagnosis of ocular hypertension/hypotension with the corresponding readings provided on the display screen;
  • patients do not have to be anesthetized to undergo the IOP measurement procedure with Easyton;
  • the vibrating rod is 100% safe to the cornea.

Indications for use

  • ocular hypertension and hypotension
  • diagnosis and management of glaucoma and other eye conditions
  • ophthalmology
  • optometry
  • orthoptics


Before you buy this eye pressure tonometer, make sure you know what cases it must NOT be used for. Thus, Easyton is never an option if the patient has:

  • upper eyelid problems, including the abnormal shape, scars, inflammation, etc.;
  • conjunctival or scleral disorders that may be worsened by the vibrating rod;
  • any condition that results in a physical failure to remain in a sitting position (spine problems, bone diseases, early postnatal or post-op recovery period);
  • brain disorders, after-stroke, or any other condition that may interfere with the measurement process;
  • affected biomechanical properties of the eyes due to surgery or any other ocular procedure.
