KERATOMETER READINGS
The keratometer readings (central corneal curvature) are important to determine:
the amount of corneal toricity
if a rigid lens will correct the
astigmatic error or if there will
be any residual astigmatism.
the base curve of the first
diagnostic lens (especially rigid
lenses)
if there is any induced change in
the corneal curvature due to the
wearing of the contact lenses
(for comparison at later visits)
