Abstract: An ophthalmoscopy lens system includes a contact lens and an image forming lens. The contact lens and the image forming lens are in a spaced-apart arrangement such that an open air space exists between the contact lens and the image forming lens and the inner surfaces are exposed.

Abstract: In accordance with one embodiment of the present invention, a positioning device comprises a microscope assembly and a lens positioning assembly. The lens positioning assembly comprises a lens support subassembly and a bi-directional positioning guide. The lens support subassembly comprises a translating rod, while the positioning guide comprises a coiled spring. The coiled spring is canted relative to a longitudinal axis of the rod. The inner periphery of the coiled spring engages in a spring loaded state an outer periphery of the rod such that the coiled spring provides a frictional force about the outer periphery of the rod. This frictional force provided by the coiled spring about the outer periphery of the rod is sufficient to hold the rod within the inner periphery, but permit infinitely variable bi-directional movement of the rod through the inner periphery under an applied force. Additional embodiments are disclosed and claimed.

Abstract: An improved fastener is provided for use in retaining vertebrae in a desired spatial relationship. The fastener has a mounting section with a first external thread to engage a vertebra. The fastener has a retaining section with a second external thread to engage an internal thread on a retaining element, such as a nut. A pair of parallel flats are formed on opposite sides of the retaining section. The flats are spaced apart by a distance which is substantially the same as or greater than a root diameter of the external thread on the retaining section. A driving recess in an axially outer end of the retaining section has arcuate corner portions which receive force to effect rotation of the fastener relative to a vertebra engaged by the mounting section. The arcuate corner portions of the driving recess are offset from a plane containing the longitudinal central axis of the retaining section and extending perpendicular to the flats.
