Fig. 18. A second Stevens hook is placed beneath the tendon, and the exposed segment is lifted out of its capsule. The tendon is secured with two double-armed 5-0 or 6-0 Mersilene sutures with spatulated needles, one 1- to 3-mm nasal to the superior rectus muscle border and the other 2- to 3-mm nasal to the first suture. Each is secured by a full-tendon, half-thickness pass through the tendon, with locking bites placed on each edge and both arms tied together in a square knot on the tendon surface.
