For Improved IOP accuracy and mires brightness:
- Set the set the slit lamp illumination to 45 degrees
- Start with the tonometer dial at 5mmHg
- Proceed with IOP measurement
- Unlike GAT, the CATS® Tonometer Prism will present distorted mires to alert users when the tip is not centered.
- After slit lamp adjustment, the CATS® Tonometer Prism mires will appear normal and round, ensuring accurate IOP measurement.
