    1. INTRODUCTION Thank you for choosing Riester Surgical Loupes. As well as giving you the highest optical quality, our stringent manufacturing controls ensure that you will obtain many years of trouble free use from your Loupes. Before attempting to work with your Loupes and in order that you obtain the best from them, we recommend that you take the time to carefully read through these user notes.
  • Page 5 To achieve the best from your Riester Loupes, they must be correctly aligned both horizontally and vertically with your visual axis (Figs. 2 and 3). Fig. 2 Fig. 3 To obtain this, your loupes may require some minor adjustments. The most common are: ADJUSTMENT METHOD Vertical alignment (height)
  • Page 6 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.

    Align each telescope as outlined earlier by sliding along the bar. (Fig. 7) Fig. 7 N.B. If you are using your Loupes in conjunction with a fibre-optic headlamp, first adjust the Loupes as described above. The light may then be adjusted to illuminate the specific area you are viewing through your Loupes.
  • Page 9 7. “FLIP UP” Riester Surgical Loupes are mounted on a specially designed hinge, permitting the telescopes to be flipped up out of view when not required (Fig. 10). Fig. 10 To avoid touching the non-sterile Loupes, a sterilisable Loupe flip lever is provided with each pair of Loupes (spares are also available).

  • Page 10: Frame Adjustments

    Over a period of time the hinge tension may slacken slightly and require adjustment. Using a small crosshead or Phillips screwdriver, adjust the hinge screw to the required tension as shown (Fig. 12). Fig. 12 8. THE LOUPE HEADSTRAP RiesterSurgical Loupes are supplied with the headstrap already fitted (spares are available).

    14. OPTICIAN GUIDANCE NOTES The set of Riester surgical loupes have been supplied to your customer with Plano lenses fitted. We hope that the following notes on lens fitting and frame adjustments will help you, help your customer obtain the best from their loupes. There are two types of binocular telescopes used in Riester loupes: Galilean based on a Galilean optical system Panoramic based on a Keplerian telescope system incorporating a roof prism.
  • Page 13 In most cases the Bifocal ADD should be the same as the normal prescription. However, some surgeons prefer the ADD to be of a power that produces a working distance similar to that of the loupe telescopes. This avoids constant accommodation as they alternatively look through the loupe and alongside for orientation.
