  • Patent number: 4453546
    Abstract: An ophthalmic instrument for controlling eye position comprising a substantially oblong shaped blade that has a textured surface and that is formed with a hole substantially in the middle of the blade. In operation, the blade is manipulated by the operator to depress against the sclera of a patient's eye for either rotating or immobilizing the globe of the eye during examination. The instrument further comprises a handle, with optional pocket clip, which is attached to the blade at an offset angle to facilitate manipulation of the blade from a position that leaves the field substantially clear for the simultaneous use of other instruments, such as an opthalmoscope.
