REPOSITION METHOD OF A POSTERIOR INTRAOCULAR LENS WITH FLATTENING OF A CILIARY BODY Russian patent published in 2019 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to eye microsurgery. For posterior chamber intraocular lens (IOL), dislocated or decentrated together with capsular sac, 2.5 mm from limb oppositely in one of oblique meridians, two through punctures of sclera and ciliary body are made in projection of haptic elements with 25 or 23 G needle respectively. Above the puncture points, one limb paracentesis of the cornea and a perpendicular oblique meridian are formed – two more diametrically located limbal corneal paracenteses. Through one of the scleral punctures (the first puncture), a needle with a loop-like thread is delivered with the dorsal portion forward over the IOL without touching it; then, the back portion of the needle is removed through the corneal paracentesis located 90 angular degrees from the first puncture. Thereafter, needle-conductor 25 or 23 G is inserted into the first puncture for a complex of IOL-capsular sac, in the area of the near haptic element, and IOL is centred, a needle cutting portion is brought through the needle guide and brought out through the first puncture. Then, hinge loop is formed from outside and tightened on haptic element IOL. Needle with suture is pricked into the first puncture and is delivered intrasklerally and intracorially through both lips of paracentesis, near to this puncture, needle with floss in back side is extracted from paracentesis outwards, an anchor knot is formed, the remainder of the thread with the needle is cut off, and the knot is immersed into the paracentesis. Same surgical actions are performed from the opposition side through the second scleral puncture.

EFFECT: method enables reducing the risk of intraoperative complications associated with reducing the degree of tissue traumatisation, reducing the probability of developing inflammatory reactions, reducing the length of the surgical intervention.
