FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely, to ophthalmology. A primary incision and two paracenteses are performed; the anterior chamber is filled with a viscoelastic agent. Then capsulorhexis is performed, as well as three or four corneal paracenteses, and three or four iridocapsular retractors (IR) are installed. The capsular bag is filled with the viscoelastic agent after the lens masses are removed. A posterior chamber IOL is implanted; a needle with a double polypropylene thread is passed through one of the loops of the intracapsular ring (ICR), followed by forming a node thereon; the ICR is implanted into the capsule bag through the primary incision, and the loop is located in the area of maximum failure of the ligamentous apparatus of the lens. After the ICR is implanted into the capsular bag, the needle is inserted blunt end first into the anterior chamber and partially removed through the paracentesis located on the side opposite from the area of maximum failure of the ligamentous apparatus of the lens. The conjunctiva is opened, and a radial incision of the sclera is performed to two-thirds of the thickness thereof; the needle is directed towards the area of maximum failure of the ligamentous apparatus of the lens using a needle holder, passing the needle between the anterior capsule of the lens and the posterior surface of the iris into the ciliary sulcus, led into said incision three mm from the limbus onto the sclera, and all IRs are removed. The resulting IOL - capsule bag - ICR complex is centred by tightening the thread, and the thread is cut from the needle, followed by melting the remaining free end of the thread by a thermocautery, forming a flange; washing out the viscoelastic agent, and hydrating the corneal incisions.
EFFECT: possibility of restoring the stability and integrity of the capsular bag intraoperatively, with the future possibility of intra-capsular implantation of a posterior chamber IOL model and preservation of the anatomical and physiological structure of the eyeball.
