RESUMO

The present research had the objective to evaluate the use of an n-butil cyanoacrylate in the fixation and maintenance of corneal autografts and aloimplants in the penetrating keratoplasty. There were used eight adult rabbits divided in two groups: the group I adhesive (GI 4 animals) and group II suture (GII 4 animals). In the GI, performed in the left eye, a penetrating keratoplasty with 5 mm in diameter received a 6 mm in diameter alogenous corneal button preserved in glycerin 98%, fixed with 4 simple interrupted stitches and with cyanoacrylate adhesive. In the right eye, the same procedure were done, but with a 4 mm in diameter defect with corneal left button that was removed (5 mm). In the GII, a similar procedure were done, but the corneal buttons were fixed with 8 simple interrupted stitches with mononylon 10-0. The pos-operatory (PO) ophthalmic evaluation were used the computer videoceratoscopy, ultrasound pachimetry and scanning eletronic microscopy. It was verified the integration of both transplants in both grafts. A bigger astigmatism grade were observed in the autotransplants from GI, and also with a lesser endothelial density. The pachimetry, were verified the decrease of the corneal thickness as the time elapsed. In all animals it was noted a complete endothelial progressive over the grafst and implants. It was concluded that the cyanoacrylate adhesive can be used as a fixative method in corneal autotransplants and also in corneal alografts in rabbits.
