Mini
(Vision Enhancing System)
Fitting Guide
1. How to demonstrate the system:
The Ocutech VES
®
Mini is available in a demonstrator kit
that uses a special adjustable frame. The kit can be ordered
with one or two telescopes, though binocular demonstration
is not recommended as the demonstrator frame mountings
are not sturdy enough to maintain proper alignment. The
two-telescope demonstrator kit is suggested as it allows for
testing the system for either the right or left eye without
having to disassemble the diagnostic telescope mounting.
When using the demonstrator frame, you can control the
height of the telescope by raising and lowering the bridge
piece. You can slide the telescope right and left to position
the eyepiece directly above the pupil of the eye chosen to
sight through the device. Confirm that the patient can see a
full, round field through the telescope, and that the image
is not cut-off to the right or left, or up or down. You may
even want to allow the patient to slide the telescope slightly
right or left themselves to position it best.
Once the position is finalized, remove the frame and
measure the distance between the center of the eyepiece
and the center of the bridge to determine the proper PD for ordering the telescope system.
Focusing is accomplished by rotating the ring at the very front of the telescope. Patients occasionally try to
turn the entire telescope to focus, rather than turning just the front ring. Warn them to NOT force the focus,
as this may break the device. Do NOT use the PD markings on top of the demo frame.
2. Indoctrinating the patient:
Once you have positioned the VES
®
Mini properly, have the patient switch their fixation in and out of the
telescope eyepiece until they get comfortable with the action. Demonstrate how to focus the device for
different distances.
Remind the patient that the VES
®
Mini enlarges images three times and as a result they should be able to
see targets three times further away than with their “normal” vision. Because of the “tunnel vision” field of
view, they will need to learn to switch their attention from the regular lens (to find the target), to the
telescope eyepiece (to see the target). They should practice this until they become comfortable and proficient.
When looking at closer distances, they should be able to see print or items that are three times smaller than
possible with their normal vision. Due to the shallow depth of field of telescopes at near, the patient can
either move their head in and out to maintain clear vision at different distances or re-focus the device to
maintain a clear image.
