Key Features

TIA™ Superfast Testing

The proprietary Thresholding Interactive Algorithm platform offers Standard, Fast and Superfast test options, designed to reduce clinic waiting times and enhance patient comfort throughout testing.

Advanced Eye Tracking

A liquid lens auto-focus eye-tracking camera produces focused images of the patient's eye for each stimulus presented. Stimuli locations tested during inadequate fixation are automatically marked and can be selected for retesting. A continuous progress bar displays fixation level and patient response throughout the entire examination.

Near Vision Test

An embedded near vision test allows clinicians to automatically verify the patient's refractive correction prior to examination. Snellen E optotypes in different orientations and sizes are presented on the measurement bowl surface, providing objective correction data for each patient.

17" HD Capacitive Touch Screen

Exam reports are generated and displayed directly on screen, allowing clinicians to interpret and diagnose without printing. The multipoint capacitive touch screen supports efficient navigation of exam options and patient data entry.

Patient Audio Guide

Automated verbal instructions are available at the preparation stage and during testing. Clinicians can select automated guidance or choose to instruct the patient personally.

Position Sensor

Forehead sensors continuously confirm optimal patient positioning. Clinicians are immediately notified of any unexpected patient movement.

Automated Motorised Chinrest

Moves up, down, left and right for precise, efficient patient positioning.

Compact Design

Slim silhouette engineered to minimise footprint without reducing functionality.
