Effects of surgical wounds hermetic closure methods in cataract extraction on postoperative corneal astigmatism

: Main factors of hermetic closure of the operation wound after cataract extraction are discussed. A new method of closing the wound in this operation is described. The opposition intracorneal mattress sutures are made across the section plane. Their principal difference is that the thread is not thrown over the external edge of the section of the cornea, as in traditional suturing, and when pulled tight, the thread does not deform the external surface of the cornea in the central zone, and thus does not induce postoperative astigmatism. Eighteen patients were operated on using this technique. Opposition sutures made after the above technique involve no high postoperative astigmatism or none at all.
