Abstract
An ophthalmic instrument for fixating a patient's eye during an ophthalmic procedure. The instrument includes a speculum securable against the patient's bony orbit, and a fixation ring attachable to the patient's eye, the ring including both a mechanism for fixating the ring with respect to the eye, and a mechanism for adjustably attaching the ring to the speculum. The instrument may include one or more bubble-type levels carried on the fixation ring for indicating the orientation of the ring and assisting the surgeon in orienting the eye of the patient before securing the ring to the speculum.
