“Measure What Matters”
Small Device...
Massive Impact.
LIOR™ is a handheld digital pupilometer
built for EMS, ER, and Neurocritical Care.
It captures pupil size and reactivity in seconds using infrared imaging, LED indicators, and a single-button interface.
Designed for field reliability, LIOR™ helps clinicians move from guesswork to standardized, objective assessment.
Where Will LIOR Make a Difference?
LIOR™ is being built to address critical gaps in neurological assessment. Whether in the field, at the bedside, or in remote settings, clinicians need fast and objective data. Manual penlights are outdated. LIOR™ replaces guesswork with reliable digital measurement. It brings standardized care to environments where precision is essential.

RESEARCH CORNER: Where does Quantitative Pupillometry (QP) apply?
Paramedic Services
Paramedics often have seconds to make decisions. LIOR™ provides clear, objective pupil data on scene without relying on ambient light or manual judgment. (Learn More)
Emergency Room Triage
Early signs of neurological decline are easy to miss. LIOR™standardizes initial assessments to help prioritize care and detect changes fast. (Learn More)
ICU and Critical Care
Sedated and intubated patients require objective monitoring of brainstem function. LIOR™ provides consistent pupil measurements to detect neurological changes that can be missed with manual checks.

Toxicology
Opioids and toxins affect pupil response before other signs appear. LIOR™ helps detect these changes with greater reliability than manual checks. (Learn More)
Remote & Low Resources
Specialist tools are often unavailable in rural or under-resourced facilities. LIOR™ brings accurate assessments to any location with minimal training. (Learn More)
Medical Training
Students and trainees can struggle with subjective exams. LIOR™ gives them a clear standard to follow, improving accuracy and skill development. (Learn More)
LIOR™ Development Journey
“From Concept to Clinical Impact”
Early Device Concept
The first concept of LIOR™, a portable, objective pupil assessment tool designed for speed and accuracy in critical emergency situations.
Prototype Schematic and PCB
The custom PCB integrates IR sensing, LED arrays, and optimized circuitry to ensure fast, reliable pupil data collection.
Pre-Prototype Design Work
The first two CAD designed models of LIOR™ with simplicity in mind: Pupil size LED array, Near Infrared Camera and Reactivity lights with a single activation button, The addition of a toggle switch to flashlight mode was added to the current design.
Clinical Workflow Optimized
The PLR-3 Logarithm is developed and the addition of a toggle switch to flashlight is added to the hardware. The device can now be used as both a pupillometer and a flashlight depending on the situation
Current Iteration and Rendering
Ergonomic, pocket-sized, and ready for frontline use, the refined LIOR™ design focuses on clinician comfort and workflow speed.
Proof of Concept
LIOR™ is on track for Validation. The PLR-3 Algorithm is currently at version 6 boasting a simulated 95% accuracy in both Pupil Diameter and Reactivity. A rotational bezel with added sights and a red focus ring around the camera lens will help the user to perfect positioning.
Introducing the “PLR-3” Algorithm
LIOR™ PLR‑3 delivers an impressive 95 % overall accuracy resulted from 50 000 AI simulated conditions with instant feedback and no added hardware beyond alignment sights and a red focus ring, supporting fast and objective assessment in EMS, ER, and ICU settings.
How Does LIOR™ Work?
During the design process the most important feature was ease of use and making LIOR™ simple to operate . Our “Click, Point, Shoot” workflow lets clinicians do just that. Click on the heading “Operational Workflow” for an video animation.
