Medical device
First portable, non-contact device to assess corneal sensitivity, a key indicator of corneal nerve function and ocular surface health.
Helps detect and monitor patients at risk of alterations in corneal sensitivity.

Innovative technology for a more compresensive eye exam

Suggested patient profile:

  • Contact lenses
  • Diabetic keratopathy
  • Dry Eye Disease
  • Previous segment surgery
  • Glaucoma

Key features

Contactless

Non-invasive and safe technology

Portable

Quick and easy to use, designed for appropriate placement in the slit lamp.

Innovative airflow technology

Uses a patented flow technology and a high-precision electronic LED positioning system.

Five standardized stimulus levels

They help to classify corneal sensitivity into different categories, serving as a guide to the degree of impact on corneal nerve function.

Replicable results outside the operator

For consistent and reliable patient follow-up.

No consumables required

Clinical value and applications

Corneal sensitivity assessment

It allows the screening of patients at risk of alteration of the function of the corneal nerves.

Patient follow-up and therapeutic assessment

Repeatability and standardisation allow reliable monitoring of the evolution of the patient’s corneal sensitivity, supporting clinical and/or therapeutic monitoring over time.

Helps with selection and follow-up in clinical trials

It facilitates the inclusion or exclusion of patients in clinical trials and helps to monitor the efficacy of therapies and the possible adverse effects of drugs on corneal sensitivity.
