In the plaque location window you can precisely position and orient the plaque and its carrier (if it has one). In most circumstances it is easier to position and orient the plaque by simply clicking & dragging it in the Patient Setup and Retinal Diagram windows. The Center button in the Retinal Diagram window automatically centers and spins the plaque (ie sets the tilt angle) to balance the suture eyelets. Eyelet balancing is explained below. Orientation controls for the carrier are also available in the Plaque window.
From the Setup Menu select.
Note: the plaque spin controls in the Patient Setup and Retinal Diagram windows also adjust plaque tilt.
