※ We highly recommend you to upgrade the software to the latest version (Over V1.0.4).

Improvement History
1. Stabilized the Auto-Tracking

2. Stabilized the pachymetry for measuring and image

3. Stabilized the movement of chinrest to avoid being stuck at bottom side

4. Added the Z-axis guide message “Front/Rear” on screen when focusing on target with

3D Auto-Tracking mode.

5. Changed movement type of X axis center (when shift the measurement type from

Tracking mode to manual mode)

6. Stabilized the serial communication for transferring data

7. After taking ACA image, Enable to take Anterior Chamber Depth value in Annotation mode
