Discover the Revolutionary Diaton Tonometer: Transforming Eye Pressure Measurement

The Diaton Tonometer stands at the forefront of eye care technology, redefining the approach to measuring intraocular pressure (IOP) with its innovative, safe, and user-friendly design. Ideal for both clinical and mobile settings, the Diaton Tonometer ensures precise and reliable IOP readings, setting a new standard in patient care and safety.

Unparalleled Safety and Precision

  • Infection Prevention Solution: The Diaton Tonometer offers a non-invasive measurement through the eyelid and sclera, eliminating direct contact with the mucous membrane or cornea. This approach significantly reduces the risk of infection, making it a safer alternative compared to traditional contact and non-contact tonometers.
  • Accurate Through Eyelid Measurement: Unique in its ability to measure IOP through the eyelid and over the sclera, Diaton provides accurate readings independent of central corneal thickness (CCT), ensuring reliability across varied patient profiles.
  • Effortless and Comfortable: Experience quick, puff-free, and painless IOP measurements, perfect for children and adults alike. With Diaton, the process is simplified, requiring no sterilization and adhering to the highest sterilization and disinfection standards set by the Joint Commission.

Enhanced Convenience and Efficiency

  • Versatile and Economical: Diaton eliminates the need for rubber covers, plastic tips, or proparacaine, making it a latex-free, environmentally friendly, and cost-efficient solution for practices.
  • Pre-calibrated for Immediate Use: Ready to use out of the box, Diaton saves valuable time and effort with its pre-calibrated design, negating the need for routine calibration.
  • Independent of Corneal Variability: With Diaton, there’s no need for pachymetry adjustments, as IOP measurements are not affected by variations in corneal thickness. This independence from CCT variability means no additional equipment purchases, further enhancing its cost efficiency.
  • User-Friendly: Designed for ease of use, Diaton can be operated by any trained personnel, supported by easy-to-follow instructional videos available in multiple languages.

Adaptable and Patient-Friendly

  • Contact Lens Compatibility: Diaton uniquely allows for accurate IOP measurements without the need to remove contact or scleral lenses, offering unparalleled convenience for both practitioners and patients.
  • Flexible Measurement Posture: Capable of delivering precise IOP readings in both sitting and supine positions, Diaton does not require special setups or ophthalmic chairs.
  • Designed for Today’s Health Concerns: With the ability to measure IOP while maintaining social distancing protocols, Diaton ensures compliance and safety in the current health landscape.

Key Features

  • Handheld and Portable: Diaton’s digital, pen-like design is non-contact and portable, offering the ultimate in convenience and mobility for IOP measurement.
  • Unique IOP THROGH EYELID or Diaton as unique Non-corneal tonometry:Corneal tonometry, including the widely used Goldmann applanation tonometry and other similar methods, may be influenced by various corneal characteristics. These factors can affect the accuracy of intraocular pressure (IOP) measurements.
  • Here are several reasons why the cornea can impact the outcomes of corneal tonometry:
    1. Central Corneal Thickness (CCT): A key factor affecting IOP measurements. Thicker corneas can lead to overestimation, while thinner corneas may result in underestimation of the true IOP.
    2. Corneal Rigidity: The biomechanical properties of the cornea, such as its rigidity or elasticity, can influence the force required to applanate (flatten) the cornea, thus affecting IOP readings.
    3. Corneal Curvature: Abnormal corneal curvature, as seen in conditions like keratoconus, can distort tonometry readings due to the uneven distribution of pressure across the corneal surface.
    4. Corneal Scarring or Opacity: Scars or opacity on the cornea can interfere with the tonometer’s ability to accurately measure the force needed for applanation, potentially leading to inaccurate IOP measurements.
    5. Corneal Edema: Swelling of the cornea can alter its thickness and biomechanical properties, impacting the accuracy of tonometry readings.
    6. Previous Corneal Surgery: Surgical procedures such as LASIK or PRK that alter the cornea’s shape and thickness can significantly affect the results of corneal tonometry, necessitating adjustments or alternative measurement techniques.
    7. Corneal Astigmatism: High levels of astigmatism can lead to variations in corneal thickness and shape across different meridians, complicating the applanation process and potentially skewing IOP measurements.
    8. Ocular Surface Disease: Conditions affecting the surface of the eye, such as dry eye syndrome, can influence the cornea’s response to the tonometry probe, potentially leading to inaccuracies in IOP assessment.

    Due to these factors, alternative tonometry methods like the Diaton Tonometer, which measures IOP through the eyelid and bypasses the cornea, can provide more reliable results in patients with atypical corneal characteristics or conditions.

“The Diaton Tonometer is not just a tool but a revolution in eye care, providing a seamless blend of safety, accuracy, and efficiency. By choosing Diaton, healthcare professionals can enhance their practice, offering superior patient care with confidence and reliability. Explore how the Diaton Tonometer can transform your approach to eye pressure measurement and patient safety at your practice today.” – says Roman Iospa, CEO of Diaton Tonometer / DevelopAll Inc.,

Diaton Tonometer in Action

Diaton Tonometer: How To

A Unique Approach

“Diaton tonometry” is a unique approach to measuring intraocular pressure (IOP) through the Eyelid and Sclera. Non-Contact (no contact with cornea), no anesthesia or sterilization required, pen like, hand-held, portable tonometer.


Emil W. Chynn, MD, FASC from Park Avenue LASEK stated, – “As a Cornea-Refractive trained specialist, I encounter many situations where Goldmann readings are inherently inaccurate–like post-LASIK, in cases of corneal edema, scarring, keratoconus, post-keratoprosthesis or transplant. In such cases, it’s both invaluable and reassuring to have the Diaton device available to measure IOP that’s independent of corneal pathology”

“It works,” said Dr. Mark Latina, glaucoma specialist (Harvard / MEEI) and the inventor of Selective Laser Trabeculoplasty (SLT), after revealing results of the study titled: “Accuracy of Transpalpebral Tonometer Diaton Compared to Goldmann Applanation Tonometer in Normal and Glaucomatous Eyes”.  “The Diaton device provides a very useful way to confirm Goldmann tonometry, especially in certain complicated patients, in my glaucoma referral practice.”

Henry D. Perry, MD (Corneal Specialist and Comprehensive Ophthalmology – OCLI), – “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.”

“The [device] is easy to use, user­ friendly, and it can be used on patients for mass screening,” Dr. Shazly said. “It’s portable, it’s economical; it’s really good for screening purposes.”

John Hope, MD, an ophthalmologist in private practice in Oklahoma City, said that he prefers the device because applanation tonometry is time-consuming and often requires support staff. Dr. Hope said that he has used the instrument routinely on every patient for at least 6 months.

“This instrument is so user­ friendly . . . there are no rubber covers to deal with, and, after the initial purchase, it is virtually maintenance-free,” he said.“I clean the instrument with an alcohol pad after each use, and it is easily portable in your pocket and can be transported from room to room or office to office.”

“There is no corneal contact and pressures can be obtained in patients wearing contact lenses,” Dr. Hope concluded. “The technique is easily and quickly learned.”
