Limbal incision with conjunctival continuous key-pattern suture in squint surgery.

This paper describes an improvement in the technique of limbal incision of the conjunctiva in squint operations. The limbal incision was first described by Zugsmith (I959) as a peritomy incision, but Massin and Hudelo (I962) were the first to show its full advantage in squint surgery, and von Noorden (i 968, i 969) improved the technique. The limbal incision has the merits of providing a scarless bulbar conjunctival incision and facilitating the performance of the surgical steps on Tenon's capsule and the muscle. It is made well away from the site on which the resection or recession of the muscle is performed and renders the suturing of Tenon's capsule easier by avoiding unwanted adhesions (Swan and Talbot, 1954; Ingram, I966).
