METHOD OF INTRAOCULAR BRACHYTHERAPY Russian patent published in 2008 - IPC A61F9/00 A61M36/00 

FIELD: medicine; ophthalmology.

SUBSTANCE: needle attached to a syringe with 2.0 ml of sterile saline solution is inserted projective to the flat part of the ciliary body. Sclerotomy is performed on the opposite side projective to the flat part of the ciliary body, and a needle with a thread are loaded in the injector, the needle is fixed in the injector, an oval silicon guide is put on the cutting surface of the needle, and the loaded injector is then inserted in the sclerotomy and moved to the prospective radiation area. The intraocular pressure is increased by injecting saline solution till the pulse of the retina stops. The needle is pushed forward through the retina, choroid, and sclera, and then the thread and needle are brought out by removing the injector. A source of beta-radiation is tied to the thread and inserted in the sclerotomy, by pulling the inserted thread the source of beta-radiation is placed on the silicon guide on the retina, the thread is fixed on the episclera, and the needle is then removed. To achieve the desired curative doze of radiation the stitched end of the thread is cut, the source of beta-radiation with the silicon guide are pulled out through the primary sclerotomy, and loop suture is applied on the sclerotomy.

EFFECT: reducing the number of complications; higher efficiency of brachytherapy.
