MEASUREMENT OF HARD CONTACT LENS
1 Make sure the unit is in the corneal curvature measurement (R/K or KRT) mode. If not,
choose the R/K or KRT mode by the .
2 Fill the concave part at the top of contact lens holder of model eye with water, and paste
the contact lens.
• The contact lens adheres by surface tension.
• Take care not to allow bubbles in between.
• Also take care and keep the measured lens surface free of water drops.
3 Insert the model eye into chinrest tissue pins.
4 Do measurement in like manner as the corneal curvature measurement.
• When measuring the base (concave) curve of contact lens, the axial angle is reversed
from the normal (convex) corneal curvature measurement.
