Reversed needle pass clear-corneal or limbal incision suturing technique using the 3-throw (1-1-1) adjustable square knot

Abstract

A single radial suture is required for a corneal or limbal incision that does not seal despite stromal hydration. In the traditional technique for placing this suture, the needle enters from the corneal side of the limbal incision and exits toward the scleral side and the suture is usually tied with a 3-1-1 surgical knot. We present an improved suturing technique in which the needle path is reversed. The needle enters on the scleral side of the limbal incision, exits on the corneal side toward the apex, and is tied with an adjustable 1-1-1 knot. © 2012 ASCRS and ESCRS Published by Elsevier Inc.
