Abstract
The disclosure relates to a joystick for positioning a test axis of an ophthalmic instrument relative to an eye of a patient. In a preferred embodiment, the joystick includes an actuator extending therefrom and arranged to alternately engage a pair of motor control switches incident to slight rotation of the joystick in opposite directions, thereby activating a motor drive to raise and lower the test axis.
