FIELD: medicine.
SUBSTANCE: invention can be used in surgical management of congenital ectopia lentis of III degree in children. Main tunnel self-sealing incision of cornea is performed with 3 mm size and two corneal paracentesis 20 G, located opposite to each other. Anterior chamber is filled with cohesive viscoelastic. Two spatulas are inserted through paracenteses and placed under the lens. Alternating position of spatulas, lens is moved through the pupil in the centre of anterior chamber. Strait needle with polypropylene thread 10/00 is passed through limbal zone of cornea and lens equator so that the lens is "stringed” on needle at safe distance from the corneal endothelium. Corneal paracenteses is used to perform paracentesis in lens capsule. By means of irrigation-aspiration system, introduced through these paracentesis into capsule, lens is removed, then the needle is removed, a capsular sac is removed with 20 G tweezer. On the neck of IOL RSP-3 "bridle" raphe is applied with polypropylene thread 10/00 using needle, then IOL is put into the cartridge so that needle with thread are located on the side of cartridge "trunk". After the implantation IOL is sewed on pupillary border of iris at 12 o'clock, whereupon iris is caught in crease at 5-7 mm, pupillary border iris is tied so that it tightly covers the lens neck, after which the suture is tied. Iridectomy is performed in the meridian perpendicular to longitudinal axis of IOL haptic elements.
EFFECT: method allows to reduce risk of cornea epithelial-endothelial dystrophy due to prevention of lens contact with its endothelium, prevent postoperative complications due to reliable fixation of IOL RSP-3 and, consequently, provide complete development of visual analyser in children.
