METHOD FOR CARRYING OUT THE NEEDLING OF A SCAR-MODIFIED FILTRATION PAD Russian patent published in 2022 - IPC A61F9/07 A61P27/06 A61K31/573 A61K47/38 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to ophthalmology. 5-fluorouracil is administered, a superficial scleral flap (SSL) is sutured to the intrascleral bed. Needling is carried out with the separation of scleroconjunctival adhesions using blunt conjunctival scissors, and intrascleral adhesions - using a disposable dissecting knife, SSL is separated by bringing the dissecting knife under it, 0.1-0.2 ml of HealaFlow is injected under the SSL. Next, an adjustable suture is applied to the sclera, for which first performed an injection into the sclera 2 mm from the free edge of the SSL, the needle is passed intrasclerally and withdrawed at 1 mm from the same edge of the SSL. Then the sclera is stitched, performing an injection 1 mm from the free edge of the SSL, passing the needle intrasclerally and withdrawing 2 mm from the free edge of the SSL; the ends of the threads are cut and left 2 mm long each. Next, take the second thread and tie it in a knot around the ends of these threads at the place of their exit from the sclera and tighten tightly, cut off the ends of the second thread, leaving them 2 mm long each, an interrupted suture is applied to the conjunctiva, 0.1 ml of a 5% solution 5 is injected under the conjunctiva -fluorouracil, the next day after the operation, non-contact tonometry is performed. If a patient has severe hypotension, the interrupted suture on the conjunctiva is opened, the knot on the suture is pulled towards the limbus, and the interrupted suture is reapplied to the conjunctiva. If hypertension is detected in a patient, the interrupted suture on the conjunctiva is opened, the knot on the suture is pulled towards the upper conjunctival fornix, and the interrupted suture is reapplied to the conjunctiva. In the case of normotension, the suture on the sclera is not regulated.

EFFECT: method makes it possible to increase the safety of the intervention, prevent excessive scarring in the operation area due to the use of the Healaflow drainage implant, as well as prevent postoperative hypotension and choroidal detachment, and postoperative hypertension.
