A method and foot pedal control for operating a microscope. A foot of an operator is placed on a foot pedal and its movement in an upward or downward direction from a neutral position is detected, with the microscope being moved in the focus-up and focus-down directions in response thereto. Similarly, the rotational movement of the operator's foot in clockwise and counterclockwise directions from the neutral position is detected, and the microscope is moved in the zoom-in and zoom-out directions in response thereto. The non-rotational movement of the operator's foot in a horizontal plane from the neutral position is also detected and the microscope is moved in a corresponding direction to provide field-of-view control. The presence of the operator's foot on the foot pedal is detected to control operation of a microscope light. The foot pedal control includes a platform housing a base member movable relative thereto and on which a foot pedal is mounted for independent rotation in a horizontal plane. A forward portion of the foot pedal is independently rotatable in a vertical plane. Movement of the base member, the foot pedal and the foot pedal forward portion in their respective planes of movement is detected to control the field-of-view, magnification and focus of the microscope.
