KEELER LOUPES
Adjustment Method
Vertical alignment (height)
(Fig 4 & 5)
= Pinch or open frame pads
Fig.4 Fig.5
Horizontal alignment (PD)
Fig.6
= Slightly loosen locking knobs
(interpupillary distance) and slide
telescope along bar (Fig. 6)
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.
Important: All Keeler 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.
The corrective actions outlined below should be followed for poorly aligned Loupes.
