SETTING UP
Look through your loupes at a target that is the correct working distance away. Look through first with
one eye closed, and adjust the alignment until a perfect image appears. Repeat this with the other
eye. Alternate closing the left and right eye to check binocularity and make fine adjustments. Once
you are satisfied that you have the best possible image, tighten the telescope locking knobs.

Surgical Loupes are accurately aligned and set for precise binocular vision. Under
no circumstances should adjustment be made by rotating or holding the telescopes, as this
may cause the telescopes to misalign and create double vision.
Examples of what is seen when looking through a poorly aligned telescope are shown below in the
column headed “Image Quality”. The cause of the poor alignment is shown alongside in the column
headed “Telescope position” and the action to achieve precise alignment shown alongside that in the
column headed “action”.
The corrective actions outlined below should be followed for each individual telescope.
