Saving Visual Acuity - Distance
You can save visual acuity for monocular and binocular vision for both unaided and aided visual acuity.
(Please refer to Figures IU-41 & IU-42.)
Right Eye
1. Press the R button, or touch R, to isolate the right eye.
2. Show the patient a chart of multiple lines of optotypes.
3. Ask the patient to choose the smallest line of optotypes he or she can read.
4. Touch the number on the screen next to that line (e.g., “20” for Snellen optotypes or 1.0 for
Decimal optotypes).
Note:
VSC = Vision (sans correction)
VCC = Vision (with correction)
Note:
This saves the visual acuity for the right eye, which appears in the data eld for the right
eye in the VSC or VCC box.
Left Eye
1. Press the L button, or touch L, to isolate the left eye.
2. Show the patient a chart of multiple lines of optotypes.
3. Ask the patient to choose the smallest line of optotypes he or she can read.
4. Touch the number on the screen next to that line (e.g., “20” for Snellen optotypes or 1.0 for
Decimal optotypes).
Note:
This saves the visual acuity for the left eye, which appears in the data eld for the left
eye in the VSC or VCC box.
Binocular Vision
1. Press the B button, or touch B, to measure both eyes.
2. Show the patient a chart of multiple lines of optotypes.
3. Ask the patient to choose the smallest line of optotypes he or she can read.
4. Touch the number on the screen next to that line (e.g., “20” for Snellen optotypes or 1.0 for
Decimal optotypes).
Note: This saves the visual acuity for Binocular Vision, which appears in the middle data eld in
the VSC or VCC box..
Note: Follow the same steps for Visual Acuity - Near as you did with Visual Acuity - Distance.
Note: The VSC and VCC boxes change to VSC-N and VCC-N when working with Visual Acuity - Near.
