Hermetic sealing of the cataract incision with intracorneal mattress sutures

: Main factors of hermetic closure of an operative wound in cataract extraction with intracapsular implantation of intraocular lens are discussed. A new method for closure of operation wound in this operation is proposed. Opposition intracorneal mattress sutures are made over the incision plane. Their principal feature is that the thread is not thrown over the external edge of corneal incision, as in traditional non-opposition sutures, and during pulling and suture the thread does not deform the external surface of the cornea in the central zone and hence, causes no postoperative corneal astigmatism. A method combining opposition and interrupted non-opposition sutures is proposed, and various combinations of these sutures are compared. Forty-five patients (45 eyes) were operated on using the proposed technique. Opposition sutures made in accordance with the methods proposed by the authors do not cause high postoperative corneal astigmatism, or it approximates the normal values of corneal astigmatism. A special marker is proposed for preliminary marking of sites for nonperforating incisions on the cornea and the site of cataract incision.
