👁 Beyond the Cornea™ The Future of Smart Contact Lenses Requires the Future of Eye Pressure Monitoring

The Next Revolution in Ophthalmology Is Already Underway
For more than a century, contact lenses have primarily served one purpose: correcting vision.

That is changing rapidly.

Today’s ophthalmology industry is entering an era of wearable eye technology. Researchers, universities, startups, and global medical device companies are developing increasingly sophisticated ocular platforms capable of far more than refractive correction. Smart contact lenses, drug-delivery systems, biosensing wearables, augmented reality optics, and continuous physiological monitoring devices are moving from research laboratories toward clinical practice.

Industry publications now routinely describe the eye as an emerging platform for diagnostics, digital health, and personalized therapy.

This transformation represents one of the most exciting periods in the history of eye care.

Yet it also raises an important clinical question that receives surprisingly little attention:

How should clinicians monitor intraocular pressure (IOP) while these technologies remain on the eye?

The Wearable Eye Creates a New Monitoring Challenge
Historically, most tonometry methods assumed direct access to the cornea.

For decades, this assumption made perfect sense.

Today’s ocular technologies are changing that assumption.

The corneal surface is becoming increasingly occupied by devices designed to remain in place rather than be removed during routine examinations.

Examples include:

therapeutic scleral lenses
extended-wear bandage lenses
smart contact lenses
drug-delivery lenses
glucose-sensing contact lenses
augmented reality contact lenses
biosensing ocular wearables
As the corneal surface becomes increasingly occupied, clinicians may increasingly ask:

Can we evaluate the eye without interrupting the technology we are trying to assess?

Dry Eye Awareness Month is also a good reminder that ocular surface comfort matters during screening.
The Diaton® Tonometer provides a corneal-independent IOP screening option by measuring through the eyelid over the sclera, helping practices add flexibility when working with:
dry eye patients
sensitive ocular surface patients
contact lens wearers
post-corneal procedure patients

Editor’s Note
This article is intended for educational purposes for ophthalmologists, optometrists, glaucoma specialists, ophthalmic technicians, and healthcare providers interested in tonometry, glaucoma screening, and corneal-independent approaches to intraocular pressure assessment. It is not intended to dismiss the role of Goldmann applanation tonometry, but to place corneal-dependent and corneal-independent IOP measurement in a more complete clinical context.

For decades, Goldmann applanation tonometry (G*T) has served as the most widely recognized clinical reference point in glaucoma care. It remains deeply important in eye care practice. Yet Goldmann, like most other commonly used tonometers, shares a basic dependency: it measures through the cornea.

That dependency matters.

In patients with relatively normal corneas, corneal tonometry may be straightforward and clinically familiar. But in modern practice, clinicians increasingly encounter eyes that do not fit the “textbook cornea” assumption on which corneal tonometry was historically built. Refractive surgery, corneal thinning, keratoconus, scarring, edema, corneal infections, scleral lens wear, keratoprosthesis, and age-related biomechanical changes can all influence the corneal surface or the way it responds to tonometry.

In those cases, a different question becomes important:

If a corneal-dependent tonometer and a corneal-independent tonometer disagree, should the corneal-independent device automatically be assumed wrong — or might the cornea itself be distorting the corneal reading?
That is the central issue this article explores.

The Diaton® transpalpebral tonometer offers a different pathway for intraocular pressure (IOP) screening. Rather than measuring through the cornea, it measures through the upper eyelid over the sclera, bypassing corneal thickness, corneal rigidity, corneal hysteresis, and many of the biomechanical variables that affect corneal-based methods. In that sense, Diaton is not simply “another tonometer.” It represents a corneal-independent measurement strategy that can complement traditional tonometry, especially in patients whose corneas may no longer behave predictably.
