METHOD FOR PHACOEMULSIFICATION IN FLOPPY IRIS SYNDROME Russian patent published in 2015 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: regional and local topical anaesthesias, as well as a standard preparation of a surgical field precede a surgical procedure. First and second corneal paracenteses 0.5-1.5 mm wide along the meridians of 1-3 o'clock and 7-9 o'clock respectively are provided. 1% Mezatone 0.1-0.2 ml is administered into an anterior eye chamber, which is then filled with viscoelastic; surgical hooks are used to pull a pupillary border of iris smoothly alternatively from opposite sides. Along a 10-11 o'clock meridian, a tunnel incision 2.0-2.5 mm long and 1.5-2.0 mm wide is created, which is followed by a continuous circular capsulorhexis, a hydrodissection and a hydrodelineation are performed after the viscoelastic is additionally introduced into the eye chamber. A crystalline lens is fragmented, an iris is held in placed with inserting a portion of small fragments of a nucleus of the crystalline lens, a portion of which is used to block the paracenteses and tunnel incision. The crystalline mass residues are removed, and a capsular sac is polished. The latter and the anterior chamber are filled with the viscoelastic, and an IOL is implanted through the tunnel incision into the capsular sac. If the iris drops out, it is reset by using the high-viscosity viscolastics with underlying hypotension; the anterior chamber is washed and sealed with normal saline. The surgical procedure is completed by administering a solution of a glucocorticoid preparation and an antibiotic.

EFFECT: method provides the balanced intraoperative pull and stabilisation of the iris tissue.
