Choice of flexible hinges
No matter what angle you need, our exclusive hinge design provides the largest range of declination to meet your surgical procedure and posture. If you are a dental surgeon the additional benefits are to your posture, either to correct poor posture or better use loupes to prevent problems for the future.
Surgical Hinge Position
For the spectacle wearer you have a choice of wearing your specs under the Keeler frame or using the RX lens holder for your prescription lenses - see below.
Maintaining stable binocularity is simple, providing the individual telescopes are mounted on an optical bench. Our pupillary distance bar (PD) is machined from a solid piece of aluminium to give your loupes a stable and precision aligned mount, no double images, no tired eyes.
