Vertex Distance Calculator

To view the current refraction data at a different vertex distance, use the Vertex Distance Calculator. Tap
the different vertex distances to display the adjusted values. Tap SE to display the spherical equivalent.
Close the Vertex Distance Calculator by tapping Exit.
Note: The Vertex Distance Calculator is for reference only. The Phoroptor VRx does not send the
adjusted data out.

Saving Visual Acuity

Visual acuity for monocular and binocular vision for both unaided and aided visual acuity can be saved
at any time in the refraction.
1. Press the R, L, or B button, or tap R, L, or B to select the right eye, left eye, or both eyes.
2. Show the patient a chart of multiple lines of optotypes.
3. Ask the patient to choose the smallest line of optotypes they can read.
4. Tap the number on the screen next to that line (e.g., "20" for Snellen or 1.0 for Decimal).
5. This saves the visual acuity for the eye(s), which appears in the data field below each eye.
Note: Follow the same steps for Visual Acuity - Near as with Visual Acuity - Distance.
Note: The VA and Unaided VA boxes change to Near VA and Unaided Near VA when working with
Visual Acuity - Near.
