The Setup menu of the Patient Setup window provides additional control over plaque location and orientation on the eye.

• Center Plaque on - Automatically places the center of the plaque over the selected location.
• Plaque Offset... - opens a dialog that allows you to rotate and tilt the plaque orientation with respect to the eye. This is used if one edge of a plaque is sitting on a muscle or the cornea.
• Plaque Location... - precisely position and orient a plaque.
• Lock Plaque Location - locking the plaque position prevents the plaque from being accidentally moved by clicking on it in the setup window. You should lock the plaque as soon as you are satisfied with the location and orientation.
• 2D Plane Tracks Plaque - when checked, the meridian 2D dosimetry plane will automatically track the central axis of the plaque as it is moved on the eye.
• Move Meridian Plane to - this submenu immediately moves the meridian dosimetry plane to pass through the selected suture eyelet or the center of the plaque..
