FIELD: medicine; ophthalmology.
SUBSTANCE: tunnel incision and corneocentesis are formed, anterior capsulorhexis is performed, the contents of the lens are removed, an intracapsular ring (ICR) is implanted into the capsular bag, and an intraocular lens (IOL) is implanted. During IOL implantation, haptic elements are placed in the ciliary sulcus. Next, the posterior capsulorhexis is performed, concentric to the anterior capsulorhexis. Then, a double capture of the optical part of the IOL is performed in the anterior and posterior capsulorhexis, while the optical part of the IOL is placed behind the capsular bag, the haptic elements remain in front of it, and the ILC located in the capsular bag is self-fixed in the corner formed by the edge of the IOL and the haptic element. In the case of severe ectopia of the lens, when the distance from the edge of the lens to the center of the pupil is less than 3 mm, suture fixation of the intracapsular ring is performed in the meridian of maximum stretching of the zinn ligaments. Next, the threads are pulled, displacing the intracapsular ring until the IOL is centered.
EFFECT: ensuring stable central position of the IOL, reduction of the risk of intra- and postoperative complications, and reduction of the risk of secondary cataract development.
