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

FIELD: medicine; ophthalmology.

SUBSTANCE: invention can be used for IOL fixation. For this purpose, a suture of non-absorbable material with thickness of 8.0 to 12.0 with needles placed at its ends is cut into two halves. Tunnel incisions of the cornea are made in the upper sector for 9–12 hours and opposite peripheral incisions of the cornea. One of the halves of the suture with a needle is delivered through the first incision of the cornea in the direction of the sclera, intralimbal, intrascleral and punctured outwards in a projection of the iridociliary sulcus in 1–3 mm. Further, from the outside to the inside, the same needle is pricked into the sclera at the same distance from the limb next to the outlet opening of 1.0 mm and the needle is inserted into the eyeball cavity, first advancing perpendicularly, then unfolding flatly under the iris in the pupil region, and bringing into the corneal tunnel incision with the help of blunt cannula 20G. Then the second half of the suture with the needle is delivered through the second incision of the cornea in the same order and brought out into the tunnel corneal incision. Then the IOL is implanted through the tunnel incision, wherein one of the haptics remains outside. Suture is tied in knots to the haptic. Needle is cut off from the suture, the haptic is immersed into the anterior chamber. IOL is rotated inside the anterior chamber. Then the second IOL haptic is picked up and lifted through the tunnel incision with the help of microtweezers and brought out. Second suture is tied to the haptic and the needle is cut off from the suture. IOL is immersed under the iris through the pupil, the suture is tied and cut. Suture ends are immersed into the thickness of the first and second corneal incisions.

EFFECT: invention makes it possible to reduce traumatization of a choroid of an eye, to reduce a risk of bleeding, to increase control of carrying out manipulations and thereby increasing the effectiveness of transscleral hemming of the intraocular lens.
