Exclusive Topcon Rotary Prism Technology

Unique Technology for Unparalleled Accuracy

The unique Rotary Prism Technology, exclusive to Topcon, allows unparalleled precision and reliability. This system measures an area of the retina while permitting measurements through pupils as small as 2mm in diameter.

1 – Objective Measurement

Step 1

Check that [OB} button is highlighted in orange.

Step 2

Using the omnidirectional joystick, align the white dot in the center of the orange box.

Step 3

When the alignment arrows disappear, the auto-shoot function is performed.

2 – Subjective VA Measurement for Far & Near Testing

Step 1

Check that the [SBJ] button is highlighted in orange. Select whether to measure far or near-distance visual acuity.

Step 2

By selecting the [REF] or [CL] button, you can check a patient’s visual acuity using values from the KR-800S or a connected topcon computerized lensmeter. The spherical lens can be changed in 0.25D steps.

Step 3

Change the visual acuity chart by tapping the chart selection button. Ask the patient to read the lowest possible line. When the visual acuity value is determined, tap the “VA” button.

*Changeable near distance is 33cm, 40cm, 50cm or 60cm.

When the Topcon brand lensmeter is connected, the data measured with the lensmeter is displayed on the CL data. *The “NoCL” sign and “0.00” are displayed if no lensmeter data exists.

3 – Glare Test

Tap the “Glare” button to activate the Glare test. Once visual acuity is determined, tap the “VA” button, and the value is displayed.

*Glare test is only available when subjective far distance measurement is selected.

4 – Grist Test**

Tap the “VA check/Grid check” button, and a grid chart will appear onscreen. Instruct the patient to look at the center of the grid and the four corners of the grid. Ask the patient if the grid is blurry, dim, or missing lines. Tap the position(s) on the grid corresponding to the patient’s answer. Once the test is complete, open all data display, and the grid test results will be displayed.

**Grid test is only available when subjective near-distance measurement is selected.

5 – Contrast Test***

Tap the “Contrast” button and the background illumination button will appear on the left side of the control panel. Adjust the contrast by pressing the + or – buttons until you obtain the lowest contrast value the patient can read (their current subjective VA). The contrast % can be changed from 2.5% ~ 100%.

***Contrast test is only available when subjective far distance measurement is selected.
