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.
