I presume that I have had the same difficulty at times that others have had in trying to grasp the superior or lateral rectus muscle. I have therefore devised a new instrument which seems to perform this function very well. It consists of a shank which is 4 cm. in length and has two blades at the tip at right angles to the shank. These blades are pressed together manually, and this maneuver causes the two needle-like extensions to slide alongside each other in a parallel manner. One can then exert as much pressure as necessary against the surface of the sclera without any danger of perforation. When the blades are closed, the superior or lateral rectus muscle is caught easily between the two needlelike extensions and held firmly. The inner surface of the blades is made somewhat concave to conform with the convexity of the sclera. The blades together
