Innovative Transpalpebral Tonometry Technology Highlights a Corneal-Independent Approach to Intraocular Pressure Measurement
NEW ORLEANS, LA | October 12, 2026 — The Diaton Tonometer, an innovative ophthalmic device designed to measure intraocular pressure (IOP) through the upper eyelid over the sclera, is being featured in connection with the American Academy of Ophthalmology (AAO) 2026 Annual Meeting, taking place October 9–12 at the Ernest N. Morial Convention Center in New Orleans, Louisiana.
Bringing together ophthalmologists, researchers, clinicians, and medical technology innovators from around the world, AAO 2026 provides an important opportunity to explore advances in eye care, diagnostic technologies, and clinical practice.
Diaton introduces a fundamentally different approach to tonometry by allowing clinicians to measure IOP without direct contact with the cornea.
THINK BEYOND THE CORNEA.™
Conventional tonometry methods, including Goldmann applanation tonometry, rely on interaction with the cornea. Their measurements can be affected by corneal thickness, curvature, biomechanical properties, previous refractive surgery, and certain corneal abnormalities.
Diaton takes the cornea out of the measurement equation.
Using transpalpebral tonometry, Diaton obtains IOP measurements through the upper eyelid over the sclera, offering clinicians an additional approach to assessing eye pressure when corneal characteristics may complicate conventional measurements.
This distinction may be particularly valuable in patients with prior LASIK or other refractive procedures, keratoconus, corneal scarring, edema, and other conditions affecting the cornea.
Advancing Practical and Patient-Friendly IOP Measurement
Diaton offers several practical advantages for ophthalmic and broader clinical settings:
- No corneal contact: Measurements are performed through the upper eyelid over the sclera.
- No anesthetic drops: Topical corneal anesthesia is not required.
- No disposable probes: The reusable measuring system eliminates the need for single-use measurement probes.
- Portable design: Supports IOP assessment in a variety of clinical environments.
- Versatile positioning: Measurements can be performed with patients seated or lying down, according to the device’s instructions for use.
These characteristics make Diaton relevant not only to ophthalmology and optometry practices but also to hospitals, emergency departments, urgent care facilities, and other healthcare settings where accessible IOP assessment may be beneficial.
A Complementary Perspective on Intraocular Pressure
Goldmann applanation tonometry remains an established clinical reference standard. However, corneal properties can influence corneal-based measurements, particularly in eyes with altered corneal anatomy or biomechanics.
By avoiding the cornea altogether, Diaton provides a different measurement approach that may offer additional clinical information.
Diaton has been evaluated in published clinical studies, including comparisons with Goldmann applanation tonometry. As with other tonometry methods, appropriate technique, patient selection, and clinical interpretation remain important.
The technology is intended to expand the options available to eye care professionals rather than replace comprehensive ophthalmic evaluation.
Supporting the Future of Eye Care
As ophthalmology continues to advance toward more accessible, efficient, and patient-centered diagnostic technologies, Diaton demonstrates how alternative measurement approaches can address longstanding clinical challenges.
Its corneal-independent measurement principle, absence of disposable measurement probes, and portable design support growing interest in practical diagnostic solutions across diverse healthcare environments.
The Diaton Tonometer’s visibility during AAO 2026 reinforces an important message for clinicians exploring new approaches to IOP assessment:
What if you take the cornea out of the equation?
