METHOD OF FORMING FILTRATION PAD AFTER FISTULIZING ANTIGLAUCOMA OPERATIONS Russian patent published in 2020 - IPC A61F9/07 A61P27/00 A61K31/56 A61K31/573 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, specifically to ophthalmology. To form a filtration pad in fistulizing antiglaucoma intervention, local peritomy, conjunctival and tenon capsule separation are performed, formation of scleral flap, internal fistula, suturing on scleral flap and formation of filtration pad. Local peritomy is 4–5 mm long. Conjunctival and tenon capsules are separated in the direction of the arch by a blunt method. Filtration pad is formed by repositioning these tissues to the initial position, and applying submerged corneal-sclero-conjunctival sutures using an atraumatic bent needle with a cutting edge and nylon 10–0 unabsorbed by the filament, performing a needle sticking in cornea at 1/3 of its thickness at distance of 0.5 mm at the edge of the incision to the centre of the limb and withdrawing it through the sclera directly on the other side of the limb, simultaneously placing a conjunctiva and tenon capsule tissue on a needle, applying 2-3 helical loops and then changing the needle direction, puncturing it in the direction from the inside to the outside in sclera by 1/3 of its thickness and then into the cornea at distance of 0.5–1.0 mm from the limb, tightening and fixing the seam with three interrupted sutures. Three loops of the first assembly are tightened; the suture is finally fixed with two subsequent nodes. Threads are cut off and the node is immersed into the transparent corneal layers by the tweezers. At the second stage from the other edge of the incision, conjunctival and tenon capsule tissues are fixed in the same way, removing both cornea-sclero-conjunctival sutures two weeks after the operation using a pull-in forceps and a blade, crossing the filament lying on the cornea in the direction from the cornea and removing all through the cornea with the knot outwards.

EFFECT: method minimizes traumatic effect on tissues during tissue incision and separation, with application of fixing sutures, minimizes response inflammatory reaction, makes it possible to carry out in postoperative period, if necessary, such manipulations as laser suturolysis, needling in order to achieve maximum functional result.
