International Vision Expo West Hosts Unique Non-Corneal Tonometer Diaton at Sands, Las Vegas 2010

Tonometer Diaton is the solution in the following cases when the use of other devices is problematic or impossible:

• Mass screening of patients.
• IOP control during clinical observation and selection of adequate hypotensive therapy for glaucoma patients.
• Serial tonometry for obtaining Diurinal curve.
• IOP can be obtained without removing contact lenses.
• IOP measuring in immobilized patients – measurement can be done sitting or supine.
• IOP measuring in children. Measurement is taken outside of the visual field.
Patients with the following conditions: chronic conjunctivitis, corneal pathology including keratitis, keratotone, corneal dimness, after penetrating keratoplastics, keratoprosthesis, laser refractive correction, high degree of ametropy, astigmatism.
• On patients with medicinal allergies.
• Lasik / LASEK / PRK (Diaton can be used for IOP measurement right after these surgeries)
• Diaton tonometry is a unique approach of measuring intraocular pressure without touching the surface of the eye, takes tonometry reading over the upper eyelid and over the sclera.

This revolutionary tonometry method allows physicians to obtain intraocular pressure without influence of central corneal thickness (CCT) and other known and unknown biometric properties and parameters of the cornea.

Unlike Goldmann tonometry which is based on the Imbert-Fick law and is effected by CCT and other corneal parameters and corneal diseases, where small area of the membrane is flattened to measure pressure of the internal fluid. Evidence shows that variations in CCT may greatly influence Goldmann tonometry reading. Parameters such as membrane elasticity, rigidity and other biomechanical properties can influence the accuracy of the intraocular pressure readings.
Diaton tonometry solves most of the corneal issues by implementing Newton’s Second Law and a Ballistic principle to obtain IOP. Readings with Diaton Tonometer are taken over the upper eyelid, at the tarsus and over the sclera, not the cornea.

Recent clinical study “Comparison of Accuracy of Diaton Transpalpebral Tonometer Versus Goldmann Applanation Tonometer, Dynamic Contour Tonometer and Ocular Response Analyzer” concluded: “Transpalpebral Tonometry is an accurate method of IOP measurement that is also independent from the biomechanical characteristics of cornea. It can be recommended for IOP measurements of patients diagnosed with glaucoma including those cases where cornea pathology or cornea characteristics have been altered”.

Diaton Tonometer will be showcased in BOOTH # MS4075 by BiCOM Inc. and Optimetrics Inc. Florida’s largest Hispanic Ophthalmic Leader. With well over 20 years of experience providing quality, new and used ophthalmic equipment and supplies to ophthalmologists, optometrists and optical retailers.

The founder, Amado Diaz, was the youngest ophthalmic dealer in the country when he started Optimetrics. His training and experience cover a wide globe of suppliers from companies like Haag-Streit, Topcon, Marco, Humphreys, Carl Zeiss, Sonomed, Tomey, Katena, RH Burton, Welch Allyn, HGM Laser, Canon, Nikon, AIT, Essilor, Vision-Ease and many others.

BiCOM Inc. (New York, USA) covers the full scope of customer service, which involves client training, follow ups, hotline support, sales support, etc. Diaton tonometer is delivered complete with training Video/DVD describing full procedure step-by-step, battery, calibration plate, carry case in addition to Test/Training Eye, which is included with each unit.
