FEATURES
- Gaze tracking is a unique fixation tracking system that records if patient is fixating properly while each stimulus is presented.
- Head tracking ensures proper alignment of the head and eye relative to the trial lens holder.
- Video eye monitoring helps to position the test eye in the center of the trial lens holder and monitor the patient during testing.
- Vertex monitoring uses the distance between two corneal reflexes to determine if the patient has moved too far back from the trial lens. The software will flag the movement and ask the operator to realign the patient or re-initialize the system.
- SITA Standard: A threshold testing method which collects the same amount of information in half the time as the original Humphrey® Full Threshold standard algorithm, without compromising test reproducibility.
- SITA Fast: A threshold testing method that collects the same amount of information in half the time as FastPac, without compromising test reproducibility
