ZEISS OPHTHALMOMETER
Aligning the instrument
With the patient positioned and
instrument adjusted, grasp the joystick
with one hand and the vertical control
extending down from the body of the
instrument with the other hand.
The hand on the vertical control
extending down from the body of the
instrument should be positioned such
that the instrument body can be rotated
to align the axis and the thumb and index
fingers are positioned to twist the
measuring screw in the center of this
control which is used to measure the
corneal power.
