Description

Innovative approach to IOP measurement opens wide possibilities and unquestionable advantages for doctors, optometrists and patients:

 

- quickness and efficiency for doctors and optometrists

- comfort and safety for the patient

- possibility of IOP monitoring during medicine adjustment

 

 

 

Spheres of diaton tonometer application

 

  - ophthalmology (including children's)

  - general medical practice

  - optometry

  - neurology

  - preventive medicine

  - occupational health

 

It has no disadvantages compared to corneal tonometera and make IOP mesuarement possible in most complicated medical cases:

- in patients with cornea pathology and allergy to anesthetics,

- after refractive surgeries,

- after keratoplasty

 

Nowadays transpalpebral scleral tonometry has no other  alternative in the world. It is the most favourable method to carry out  preclinical medical research of the population and , moreover, it works in such  complicated clinical cases when it is impossible to use  classical tonometry methods. Diaton is a helpful tool for ophthalmologists faced with pediatric patients or who have corneal abnormalities such as corneal edema, erosions or keratoprostheses.

Approved by the FDA in 2006, the instrument has been the subject of numerous clinical trials, where it has been found to be comparable with the gold standard, the Goldmann tonometer, and with many other devices.

 

 

Innovative approach to IOP measurement opens up wide medical opportunities and undisputable benefits both for doctors &  patients:

For doctors:

  Accurate results

  Wide range of medical opportunities

  Quick & efficient  procedure of measuring (IOP measurement takes several seconds)

  Сreates an image of a modern doctor working in an up-to-date equipped medical center

  Wide medical opportunities

  Low dispensable materials' expenses

For patients:

  No contact to the cornea

  No risk of infection

  No anesthesia drops

  No pain

  No need to take out contacts

 

Diaton tonometer is the unique Non-Corneal tonometer  of intraocular pressure (IOP) through the Eyelid, without any contact with the cornea and no use of anesthetics.

The technical know-how applied in Diaton makes this device unique in the world.  

 

Transpalpebral Diaton tonometer is effective and irreplaceable in complicated medical cases:

 

 

 Can measure IOP even in the presence of viral infections, allergic reactions, dry eye syndrome, contraindications for corneal tonometry

 Can serve as non-invasive day monitoring tool while selecting the adequate hypotensive medical treatment

 Can measure IOP  on patients after corneal surgeries

 Сan measure IOP with contact lenses on

 Can measure IOP on immobilized patients

 Screening tool for elevated IOP by PCPs

 Trained family members  can monitor IOPs of glaucoma patients at home

 

Comparative tests of Diaton tonometer and Goldman tonometer give the evidence of high reliability that diaton tonometer guarantees.

 

Thus, cornea thickness is the important factor of IOP evaluation and monitoring and requires the necessity of including corneal pachymetry

in the program of examination the patients with suspicion of glaucoma and hypertension, especially after various keratorefractive surgeries while

using the traditional corneal methods of ophthalmotonometry. At the same time clinical application of transpalpebral scleral diaton tonometer makes

it possible to evaluate IOP using only one device, the procedure being efficient, economical, simple in performance and requiring no additional instrumental examination.

 

 

Here you will find a scientific reports for clinical use of the Diaton Tonometer in Medical Practice.

Non-Corneal Tonometer Diaton

Specifications

Diaton tonometer is the unique Non-Corneal tonometer  of intraocular pressure (IOP) through the Eyelid, without any contact with the cornea and no use of anesthetics.

The technical know-how applied in Diaton makes this device unique in the world.

Technique of measurement with Diaton tonometer, grounded on measurement of elasticity of an eye is conducted by free pressure for the superior eyelid by a rod of the device. The device measures the value automatically, according to eye pressure in mmHg. The device has the small size (17,4х2,6х2,0cм), light (89gr), outwardly resembles the pen.

 

At realization of a procedure the patient can by in sitting or reclining position.He is asked to look upwards angularly 45 degrees. The tip of the device will set close to eyelashes edge so that it will be placed in the middle of imaginary vertical to an eyeglobe. For correctness of the installation the device is provided with beep. If the device is established not upright, the buzzer sounds, at the exact installation the buzzer becomes silent. The measurement is made up to 6 times, the average result is injected on the display by pressing the key.

Diaton Tonometer

The pen-like device, the transpalpebral Diaton tonometer measures intraocular

pressure (IOP) through the eyelid and requires no direct contact with the cornea, as other methods have necessitated.
