METHOD OF FLANGE-LOOP TRANSSCLERAL FIXATION OF DEPLOYED COMPLEX "INTRAOCULAR LENS - CAPSULAR BAG" Russian patent published in 2023 - IPC A61F9/07 A61F2/16 

FIELD: medicine; ophthalmology.

SUBSTANCE: in the proposed projection of the ciliary sulcus, parallel to the limbus, 2.5 mm away from it, a non-through scleral tunnel is performed transconjunctivally for 2/3 of the sclera thickness, 4.0 mm long. With a 30g guide needle, preliminarily bent at the base at an angle of 120 degrees, with a 7-00 thick polypropylene thread inserted into it to a depth of 20 mm, the sclera is punctured through the formed tunnel and the guide needle is inserted under the complex "intraocular lens (IOL) — capsular bag (CB)" in the projection of the near haptic element of the IOL. Next, the posterior capsule is perforated with a guide needle from bottom to top, after which the end of the thread is removed from the guide needle and the guide needle is moved to a position above the IOL-CB complex above the haptic element. Then, the same end of the thread is inserted into the guide needle to a depth of 20 mm, and through the same scleral puncture, the guide needle is pulled back out of the eye, thereby forming a loop thrown over the IOL haptic element. Next, the IOL-CB complex is centered by tensioning the ends of the threads, after which the ends of the thread brought to the sclera are dried, and then a double flange is formed from the two ends of the thread located above the sclera using a coagulator up to the sclera. Then the flange is completely immersed in a blind scleral tunnel, the conjunctival incision is coagulated.

EFFECT: method allows to simplify the technique and reduce the morbidity of fixing the IOL-CB complex, reduce the operation time, ensure reliable fixation of the complex, its stable position in the postoperative period.
