METHOD FOR TRANSSCLERAL FLANGE FIXATION OF INTRAOCULAR LENS Russian patent published in 2024 - IPC A61F9/07 A61F2/16 

FIELD: medicine.

SUBSTANCE: invention relates to ophthalmology and can be used in ophthalmic surgical practice for fixation of haptic elements of an intraocular lens, IOL, if it is impossible to implant the IOL into a capsular sac or into a ciliary sulcus supported by an anterior lens capsule. That is ensured by forming corneal paracenteses at 3 and 9 hours, a tunnel limbal incision at 11 hours, as well as scleral pockets with preliminary separation of conjunctiva at 6 and 12 hours. Haptic elements of the IOL are stitched before implantation into injector with 6-0 polypropylene suture needle. Flanges fixed in haptic elements of the IOL are formed at the ends of the sutures with the help of a coagulator. Pre-pierced IOL is implanted into the posterior chamber of the eye with the help of an injector through a small corneal incision for 11 hours. Then, through the previously formed scleral pocket for 6 hours, the sclera is punctured with injection needle 29G parallel to the iris, which is used as a guide for a needle with a thread, which is introduced into the anterior chamber with the help of microtweezers and then through the scleral pocket. Similar manipulations are performed with a scleral approach for 12 hours. IOL is centered by pulling up the suture ends for 6 and 12 hours. Suture ends are cut off and external flanges are formed with subsequent immersion into the scleral pocket and the conjunctiva suturing in this area.

EFFECT: invention allows minimizing the risk of repeated IOL dislocation due to stable IOL fixation with reduced duration and traumatism of the operation.
