A new instrument to simplify encircling buckle placement

Abstract

Purpose:

The purpose of this study is to describe a new surgical instrument that simplifies 360° silicone band placement, alone or in combination with pars plana vitrectomy, for the treatment of rhegmatogenous retinal detachment.

Methods:

The instrument has a straight shank and a curved component in the form of a partial helix, whose purpose is to encircle the perimeter of the eye globe below the rectus muscles. The distal tip of the helix is inserted through a small conjunctival incision in the superior temporal quadrant, and the shank is rotated 360° on its axis until the tip emerges from the insertion point. One end of the silicone band is sutured to the tip, and the instrument is rotated in the opposite direction until both ends of the band are positioned in the same scleral quadrant. The band is sutured to the sclera and the conjunctival incision is closed. Pars plana vitrectomy can then be performed using transconjunctival microincision techniques through the intact conjunctiva.

Results:

Our experience using the instrument in more than 100 procedures has shown that the new technique considerably reduces surgical trauma: wide opening of the conjunctiva is obviated, there is little manipulation of the extraocular musculature, and only a few sutures are needed. The duration of the procedure is considerably shorter because of the smaller number of surgical maneuvers.

Conclusion:

We describe a new scleral technique facilitated by this surgical instrument, whose objective is safe and effective placement of an encircling silicone band with minimum trauma and a reduction in operating time.
