METHOD FOR AHMED ANTIGLAUCOMA VALVE IMPLANTATION IN REPEATEDLY OPERATED GLAUCOMA Russian patent published in 2024 - IPC A61F9/07 A61M27/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to ophthalmology, and can be used for implantation of antiglaucoma valve Ahmed in repeatedly operated glaucoma. That is ensured by a conjunctival incision in a superior temporal quadrant along a limb. Conjunctival flap is formed between two rectus oculomotor muscles. Tenon's capsule is cut off from episclera to form a conjunctival pocket. Valve body is placed in the formed conjunctival pocket and fixed to the sclera. L-shaped scleral flap is cut out with its base to limb sized 5 mm by 3 mm in a zone free from scleral scars. Two additional scleral flaps sized 2 mm by 4 mm are formed, their long side perpendicular to the tube, bases on different sides of the tube for fixation of its bend with interval of 2 mm. Paracentesis is performed for 9 o’clock, and 0.2 ml of viscoelastic is introduced into the anterior chamber. Then the valve tube is cut and implanted into the anterior chamber. Scleral flap is closed with 4 interrupted sutures along the edges. Each additional scleral flap is sutured with 1 interrupted suture to the sclera. Then Tenon's capsule is pulled in a tube projection and fixed with two interrupted sutures. Conjunctival incision is sealed with interrupted sutures to the limb.

EFFECT: invention enables avoiding the risk of valve tube protrusion, implanting the valve in the superior temporal segment, achieving a stable hypotensive effect, as well as preserving visual functions.
