OPERATING PROCEDURE: Contact Lens Measurement
3.10 Contact Lens Measurement
To measure hard contact lenses, use the provided contact lens holder.
The contact lens holder is incorporated in the spherical model eye.
1
Fill the concave top of the contact lens holder with water.
Use a commercial pipette to fill the concave top of the CL holder completely with water.
2
Place a contact lens on the contact lens holder with the surface to be measured fac-
ing upward.
When measuring the concave surface, place the lens with the concave surface up. Conversely, when
measuring the convex surface, place the lens with the convex surface up.
3
Remove the two fixing pins and the stack of chinrest paper from the chinrest.
4
Place the contact lens holder with the surface of the contact lens to be measured fac-
ing toward the measuring window and insert the fixing pins.
5
Select KM measurement mode and measure the contact lens in the same manner as
KM measurement.
• Prevent any bubbles from forming. In addition, avoid water or dust to the measurement surface.
• When the convex surface of a contact lens is measured, the axis angle can be read directly. When
the concave surface is measured, however, the measured axis is reflected over the Y axis.
• Soft contact lenses cannot be measured.
