Tied and tidy: closing the conjunctiva over adjustable sutures

Adjustable sutures have revolutionized strabismus surgery. Numerous techniques have been described that aim to facilitate postoperative adjustment. Nevertheless, some sort of procedure is always necessary following adjustable suture surgery and has to be arranged within 24 hours. Where no adjustment is required, the muscle needs to be secured at the existing position and the conjunctiva, sometimes left on a loop, has to be tidied up and sutured.

As fewer than half of the operated on eyes need a final adjustment, we describe a technique whereupon the muscle is left on a loop and the conjunctiva is closed over it with two interrupted polyglactin 910 sutures. If an adjustment is deemed necessary, one of the sutures has to be cut and replaced at the end of the procedure. When the result of squint surgery is satisfactory and no muscle movement is needed, no further manipulation of the conjunctiva is required.

In a series of 17 patients, we have found this technique to be excellent for patient comfort and time efficiency. We have not encountered any muscle slippage. We think that the ease of postoperative management may tend to bias the surgeon against adjustment.
