In full-thickness keratoplasty, with cylindrical graft, the majority of the mechanical postoperative complications are consequences of bad coaptation of the graft, due to some defect in the section or in the fixation. The use of instruments of first quality and the edge-to-edge suture have nearly eliminated them.1

At first fixation was accomplished in 4 mm. grafts by using the sharp and very polished Vogt's suture needles, manufactured by Grieshaber and threaded with 000000 silk; placing two points at the extremes of the vertical meridian and progressively increasing its number until they are equal or even superior to the number of millimeters of the diameter of the graft.2

The "sharp side," on Vogt's needle, has been modified to place it in the convexity, in order to safeguard the bridge of the tissue at each side of the wound,3 which is attempted to be joined with the suture, making
