Instructions for Use

Vertex Distance Calculator

The Vertex Distance Calculator converts the Subjective refraction data to different values for each vertex
distance. (Please refer to Figure IU-40.)
You can:
• Access the Vertex Distance Calculator by touching VD on the menu bar, which is located at the
bottom of the screen.
• Recalculate the Sphere, Cylinder, and Axis values by touching the desired vertex distance
number screen icon.
• Calculate the spherical equivalent of the refraction data by touching SE.
• Close the Vertex Distance Calculator by touching EXIT.
Note: The Vertex Distance Calculator is for reference only. The Phoroptor VRx does not send
the Vertex Distance Calculator data to EMR.
