FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to ophthalmology. To treat scarring of the Tenon capsule around the Ahmed antiglaucoma valve, an L-shaped conjunctival incision is made 10 mm from the limbus, 5 mm long parallel to the limbus and 7 mm long perpendicular to the limbus, in the projection of the lateral edge of the valve body. Next, the conjunctiva is separated from the Tenon capsule and a section of the Tenon capsule measuring 6 by 6 mm above the valve body is excised, starting from the lateral edge towards the center, exposing a part of the valve body and one of the two sutures fixing the valve body. The rest of the Tenon capsule is fixed with one interrupted suture with 8.0 silk thread to the fixation hole in the valve body. A HealaFlow drainage implant with a volume of 0.2-0.3 ml is inserted over the exposed part of the valve body and near it along the incision. After that, the edges of the wound are compared and fixed with a continuous suture with a silk thread 8.0.

EFFECT: method allows to stabilize IOP and prolong the hypotensive effect of antiglaucoma surgery.
