| Left/Right Sliding Headrest |
| A sliding headrest enables easy head positioning for the patient to ensure fast and comfortable measurements. The operator simply slides the headrest to the left or right position and invites the patient to position their head against the comfortable headrest pad. The AT555 automatically detects which eye is being measured.
|
| Bright LED Array for fast fixation |
| The AT555 nosepiece contains an array of bright red LEDs. These provide an obvious visual cue to the
patient for fast fixation and alignment, thereby reducing measurement time.
|
| Operator Interface |
| An "eye" icon on the display shows the operator how the instrument's auto alignment system is positioning itself to make a measurement.
|
| Patient comfort is maximized |
| The AT555 does not utilize chinrests, joysticks or elevation controls. Patients simply view a fixation target - and moments later experience the gentlest air puff available on any NCT. The procedure is fast, quiet and convenient, with no patient discomfort.
