ALCON HAND HELD AUTO-KERATOMETER
Controls
The hand unit, as seen from the examinerís
side, has a display window and a number of
buttons which control the functions of the unit.
The top, left button is the scroll button.
When this button is repeatedly pushed
it toggles through the various different
setting for the instrument. Use the select
button to change the settings. With this
you can:
1. Set it to read base curve (dioptric
and radii) or sphere/cylinder which
gives the sphere and cylinder as well
as delta K for the corneal toricity.
