FIELD: medicine.
SUBSTANCE: invention relates to ophthalmology and can be used in carrying out cataract phacoemulsification in patients with crystalline lens subluxation, resulting from expressed weakness of Zinn's ligaments or their local defect, complications induced by increased mobility of capsule sac, reduction of probability of developing inflammatory reactions and bleeding, as well as reduction of degree of eye tissue trauma. Main cornea cut and two cornea paracenteses are made. Scleral-conjunctival flaps are formed. Visco-elastic is introduced into anterior chamber. After performing crystalline lens hydrodissection and its separation from capsule sac through main cornea cut intracapsule implant in form of open ring with openings on ends is introduced into capsule sac. Implant is placed in such way that its open part is projected on the middle of zone of Zinn's ligaments defect. Openings on the ends of implant are displaced into area of capsulorexis. Through one of cornea paracenteses (first paracentesis) into eye cavity introduced is first curved needle with thread (first needle) to other end of which second curved needle (second needle) is fixed. First needle is passed sequentially from bottom to top through openings on implant ends. Then first needle is brought out through second cornea paracentesis (second paracentesis). After that first needle is introduced through second paracentesis, and second needle - through first paracentesis. Needles are passed from inside outside through ciliary furrow above capsule sac and brought out under preliminarily formed scleral valve onto external surface of sclera in zone corresponding to the middle of zone of Zinn's ligaments defect. After preliminary tightening and centration of capsula sac thread are fixed to sclera. After that removal of cataract with implantation of intraocular lens is performed.
EFFECT: reduction of risk of post-operation complications induced with increased capsule sac mobility, as well as reduction of probability of developing inflammatory reactions and bleeding, as well as reduction of degree of eye tissue trauma.
