The curved needle (with cutting edge) threaded with cotton or 6–0 silk suture is passed under the area held by the forceps to include the muscle also in the bite (Figs. 1c and 2c).

The thread can then be held taut and fixed to the drape using an artery forceps (Figs. 1d and 2d).

Tips




(a)

In cases where the incision is placed at 12–0 clock, the superior rectus bridle suture is applied.

 

(b)

When the suture is pulled back, the globe tends to turn down because the superior orbital margin acts as a fulcrum to allow this movement.

 

(c)

If the incision is placed temporally, the lateral rectus bridle suture is applied.

 

(d)

The lateral rectus suture, when pulled back, moves the globe more laterally as there is no brow effect here.
