METHOD FOR DEPOSITION IOL-CAPSULAR BAG DISLOCATED COMPLEX Russian patent published in 2021 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, specifically to ophthalmology. For reposition of the dislocated IOL-capsular bag complex, limbal paracentesis and scleral puncture are formed. First, a polypropylene filament is made in an injection needle combined with a hollow handle, forming a loop from the pricked end; the needle is bent at an angle with the needle cut upwards. At 2.5 mm from the limb in the projection of the haptic element, a through puncture of the sclera and the ciliary body by the injection needle is performed, and after alignment of the IOL-capsular bag complex, located under it, the capsular bag is perforated in the projection of the pupil, at the point of optic-haptic transition from one side of the haptic element. First loop is removed into a paracentesis; after that, the needle is brought under the haptic element from the other side, and after perforation of the capsular bag in the projection of the pupil, the second loop is removed from the anterior chamber into the same paracentesis. After the needle is removed from the eye, the first and second loops are dissected. Duplicate portion of the suture is removed, and the remaining ends of the suture are interconnected by nodes to form a third loop, which is immersed into the anterior chamber, and then through the pupil into the posterior chamber, and fixed on the surface of the IOL-capsular bag complex. Further, the same actions are performed with the second haptic element of the IOL using the same paracentesis. Thereafter, the IOL-capsular bag complex is fixed to the sclera to allow immersing the formed nodal suture into a space between the episcler and tenon membrane.

EFFECT: method reduces invasiveness of reposition of the dislocated complex IOL-capsular bag, increases reposition efficiency, reduces the risk of eye tissue injuries.
