METHOD OF SEALING CORNEAL DEFECT WITH CONJECTIVAL FLAP ON NUTRITION PEDIC IN COMBINATION WITH TAMPONADE WITH AMNIOTIC MEMBRANE WITH SUTURE FIXATION Russian patent published in 2023 - IPC A61F9/00 A61F9/07 

FIELD: medicine; ophthalmology.

SUBSTANCE: corneal defect is sealed with a conjunctival flap on a pedicle in combination with amniotic membrane tamponade with suture fixation. The conjunctiva is cut out in the form of a flap on the feeding pedicle at the limbus in its semicircle that corresponds to the location of the wound. Then the prepared amniotic membrane is placed on the cornea and straightened, after which it is folded into 4 layers and the corneal tissue defect is tamponed with it, and a needle is passed through the edges of the wound. Next, the edges of the corneal defect are tightened with an interrupted suture. Then, using a pedunculated flap of conjunctiva, the deepithelialized cornea is covered, covering the defect area, and in this position, the conjunctiva is fixed along the periphery with separate interrupted sutures at intervals of 1 mm.

EFFECT: method provides reliable sealing of the eyeball in the presence of a deficiency of corneal tissue in the case of perforation due to an inflammatory process or in case of a penetrating wound of the eyeball with a perforated wound of the cornea.
