FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely, to ophthalmology, and can be used in carrying out cataract phacoemulsification in patients with defects of Zonulae Zinni along large length. Before the stage of performing continuous capsulorexis (CCR) of lens, first conjunctival flap is formed in projection of zone of the middle of Zonulae Zinni defect and the second - in the opposite meridian. Through main corneal cut by means of injector first ICR is introduced in capsule sac in form of open ring with loops on the ends, its diameter being 1.5-2 mm larger than diameter of capsule sac, one of ICR ends is bent inside in form of one coil of flat spiral, to whose loop preliminarily fixed is thread, on opposite end of which curved needle (CN) is located; after that, first ICR is placed in such a way that its bent end projects in the zone corresponding to the middle of Zonulae Zinni defect, then, end with thread is brought out on the surface of anterior capsule in the area of capsulorexis; after that, CN is introduced into anterior chamber and passes successively from inside outside above capsule sac under iris and is brought out on external surface of sclera through ciliary sulcus, in the region of preliminarily separated first conjunctival flap, then by pullinh the tread, capsule sac is centered, after which thread is fixed intrasclerally with zig-zag stitches. After that, second ICR, identical to the first one, in implanted into capsule sac through main corneal cut and placed in such a way that its bent end is in segment, opposite to bent end of first ICR, then end of second ICR with thread is brought out on the surface of anterior capsule in the area of capsulorexis, then, like first ICR, second ICR is sewn with the tread which is intrasclerally fixed in the area of preliminarily separated second conjunctival flap, and after that hydrodissection and hydrodelineation of lens, phacoemulsification of cataract and implantation of intraocular lens are performed.
EFFECT: method makes it possible to achieve reconstruction of circular symmetry and preservation of capsule sac integrityt, reduction of risk of post-operation complications, associated with its higher mobility, ensuring stable position of intraocular lens, reduction of risk of development of inflammatory responses and bleeding, reduction of degree of trauma of eye tissues, as well as obtaining high clinical and functional results in early terms after surgery.
