REPOSITION AND ANCHORING METHOD OF A TORIC INTRAOCULAR LENS, DISLOCATED WITH A CAPSULAR SAC OR WITHOUT CAPSULAR SUPPORT Russian patent published in 2019 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, specifically to ophthalmology. For reposition and anchoring of a dislocated toric intraocular lens (TIOL) within the posterior chamber, with breaks of both the anterior and posterior capsules, and in the TIOL rotation, the TIOL position axis is determined before the operation. That is followed by marking the patient's horizontal axis in an operating room in the patient's sitting position under anaesthesia. Further, in the prone position, an axis of the previously defined TIOL position is marked on the cornea. Two corneal paracenteses are made, an anterior chamber is filled with a viscoelastic. Then using vitreous cutter perform two pairs of colobomas, one pair in areas of expected fixation of TIOL, one coloboma on each side of previously marked position axis of TIOL, wherein centres of every coloboma are located 1.5 mm from TIOL position axis, and line connecting centres with colobomas is perpendicular to said axis. TIOL is then oriented according to the previously determined location of TIOL, enters through paracentesis with a needle with a thread in one of the colobomas, piercing the front leaf of the capsule of the lens and passing under the haptic element TIOL, is removed through the neighboring coloboma, needle is pricked with cornea until place of connection of needle with suture comes out of coloboma. Needle is then removed from the cornea in the opposite direction through the same paracentesis, the needle is cut off and a nodular suture is formed. Said sequence of actions with needle with thread is repeated with other pair of colobomas, washing out viscoelastic from anterior chamber, paracentesises are hydrated. At the end of operation dexamethasone and an antibiotic are injected under a conjunctiva.

EFFECT: method improves non-correlated visual acuity, speeds up rehabilitation, eliminates formation of an irregular oval pupil shape, reduces a risk of postoperative inflammatory reactions, and also improves quality of life.
