Weis procedure for Entropion Treatment

Weis (transverse tarsotomy) procedure for the correction of entropion. This procedure everts the lid margin and produces an anatomic barrier that prevents preseptal orbicularis muscle override and secondary tarsal rotation . It has been advocated for involutional entropion but is best suited for patients with varying degrees of cicatricial entropion. The Weis procedure has been called the two-snip procedure and is relatively easy to perform. A stab incision is created through the full thickness of the lid at the inferior aspect of the tarsus approximately 3 mm from the eyelid margin . A sharp iris scissors is used to extend the full-thickness lid incision nasally and temporally (hence the two-snip procedure).

The short vertical height of the tarsus of the lower eyelid,especially in patients with cicatricial entropion, makes the incision of the tarsus challenging. An alternative method of creating this full-thickness horizontal eyelid incision is to make partial thickness lid incisions with a number 15 blade through skin and orbicularis muscle externally and conjunctiva and tarsal plate internally. Each of these incisions is placed 3 mm below the lid margin. Any remaining tissue can be cut with scissors. Ideally, the incision is through the inferior portion of the tarsus; however, this may be difficult and the incision may occur just below the inferior border of the tarsus. As such, the procedure may be better described as a transverse blepharotomy. Rotation of the tarsus is accomplished by placing horizontal mattress sutures (5-0 chromic) originating from the conjunctiva and lower eyelid retractor, then extending to an infra-lash position . Tying these sutures will evert the eyelid margin and also stabilize the orbicularis muscle. Lance and Wilkinsevaluated patients treated with a Weis procedure alone and found the recurrence rate to be 11%. However, when a lateral canthal tightening procedure was added, no recurrences were encountered. Thus, if the Weis procedure is used to treat involutional or cicatricial entropion with horizontal laxity, it is best coupled with a tarsal strip procedure to further stabilize the eyelid margin.

Full thickness incision in the lower edge of the tarsal plate will allow you to dissect easily conjunctiva from retractors. Perform an advancement of them over the anterior surface of the tarsal plate.
