Major Advantages & Benefits of Diaton Tonometer:

     1. Safe Tonometry = No Risk of Infecting No Contact with Mucous Membrane or Cornea (safer vs other contact or noncontact tonometers) Infection Prevention Tonometry Solution

     2. Measure IOP THROUGH Eyelid and Sclera (No contact with eyeball or the cornea, IOP independent of CCT)

     3. Quick, Puff-free & Painless (Perfect for children and squeamish adults)

     4. No need for Sterilization (contact only with eyelid. Meets and Exceeds JCAHO Joint Commission Sterilization and Disinfection Standards)

      5. Enables to Measure Accurate IOP even with Contact Lenses or with Scleral Lenses ON (Only with Diaton)

      6. Can Accurately measure IOP in sitting or supine position. (no special set up or ophthalmic chair needed)

      7. Social Distancing & Tonometry Compliance – Diaton user can stand on the Side of the patient vs in Front (at arm’s length, away from the line of breath or cough)


Convenience and Cost Efficiency:

     1. No Rubber Covers, Plastic Tips or Proparacaine (Latex-free, Green, Cost Efficient)

     2. No Calibration Diaton is pre-calibrated by design. Ready-to-use. (saves time and efforts)

     3. No Pachymetry (CCT) adjustments needed for Diaton tonometry variability of Central Corneal Thickness (CCT) may greatly affect corneal tonometry device results in either direction. IOP results with Diaton tonometer are completely independent of thin or thick corneal biometrics as IOP with Diaton is measured via Sclera and not via Cornea as all other tonometers (No need to purchase a pachymeter, saves time and efforts)

     4. Easy to use. Can be used by any trained personnel (easy to follow step-by-step video instructions in 5 languages)

     5. Complimentary 2-way video training  Saves time on staff training, includes helpful tips and best practices.

Diaton Tonometer in Action

Who Uses the Diaton Tonometer?

Diaton Tonometer is intended for use by Ophthalmologists, Optometrists, Ophthalmic technicians as well as Inpatient & Outpatient Clinics such as Hospitals, Emergency Department / Emergency Room, Urgent Care Clinics, Nursing & Elderly Homes, General & Specialty Practitioners as well as for Mass Glaucoma Screening purposes and medical missions.

Non-corneal, Scleral Diaton tonometer is particularly useful in cases where standard direct applanation (corneal) tonometry is difficult or not viable, such as with pediatric patients, in presence of certain corneal pathology, edema, infection, following corneal surgery, keratoconus, KPro and in cases of eye trauma.

Articles, Clinical Studies and Press:


“There has been a Renewed Concern about whether Scleral Lenses cause Increase in Intraocular Pressure.”
Multiple Clinical Studies showed IOP to elevate by ~5-10 mmHg regardless of scleral lens diameter worn.
Eye care practitioners that fit sclerals now Need to Measure & Monitor IOP with Scleral Lenses ON the eye!

IOP monitoring with Diaton minimizes the risks & liabilities for practices and increases the level of patient care.
Contact lens Spectrum covered the topic in detail:

2. CLS Article: Does IOP Increase During Scleral Lens Wear?  By PROF. PATRICK J. CAROLINE & MARK P. ANDRÉ Link: https://www.clspectrum.com/issues/2019/september-2019/contact-lens-case-reports


4. Tonometry & Infection Prevention Solution: IOP THROUGH EYELID – NO CONTACT WITH MUCOUS MEMBRANE
Emergency Medicine Adopts New Tonometer that let you measure IOP THROUGH EYELID – No Contact with Cornea or Any Mucous Membrane.

5. Practice Safe Tonometry: Transpalpebral Diaton Tonometer nowadays is the SAFEST tonometer on the market as it does not touch the mucous membrane or cornea.

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.”
