In operating for enucleation one is often disappointed at the small section of optic nerve obtained attached to the globe. Occasionally the nerve is cut at its insertion into the globe, so that no portion of the nerve is obtained for laboratory examination.
The instrument pictured here was devised to enable one to obtain a good section of optic nerve. The elevation on the anterior blade is approximately 6 mm. When the scissors are inserted inside the capsule funnel and straddle the optic nerve, the act of closing the blades automatically raises the globe and puts the optic nerve on the stretch. Incidentally, the globe is protected from being cut or injured. The nerve is then cut by the lower blade.
The amount of nerve obtained is always equal to the height of the elevation on the upper blade and sometimes more. There should be no difficulty in inserting the
