FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely ophthalmology. The haptic elements of the intraocular lens (IOL) or the iris-lens diaphragm (ILD) or the technological element of the intracapsular ring (ICR) or segment (ICS) are captured with bayonet knot. Next, transscleral suture fixation in the ciliary furrow is carried out, the knot are pinched and the ends of the threads are covered in the thickness of the sclera. For fixation, double non-absorbent threads with a cross section from 10-0 to 6-0 are used. Then the threads are passed through the main sclera-corneal incision outward through the ciliary furrow using the ab externo or ab interno transsclerally and, without opening the conjunctiva, IOL or ILD is implanted into the ciliary furrow, ICR or ICS is implanted into the capsule sac. Next, the threads are passed intrasclerally paralimbally for 2-4 mm, inserting each of the needles into the sclera at the points of the exit of the threads from the conjunctiva. Then the threads are again brought out through the conjunctiva, the threads are cut off with the free ends left, knots are formed with tension for their immersion in the scleral channels. Further, at the exit points of the ends of the threads from the conjunctiva, additional needles with double threads are inserted again in the form of a loop, which are again passed intrasclerally paralimbally for 2-4 mm and brought out through the conjunctiva. Then the ends of the threads fixing the IOL, or ILD, or ICR, or ICS, are captured in loops and immersed in the scleral channels formed by additional needles.
EFFECT: method provides the implantation of a posterior chamber IOL with capsule-free aphakia, ILD with aniridia and capsule-free aphakia, as well as ICR or ICS with defects of ligaments of Zinn with their transscleral fixation with reinforced sutures without opening the conjunctiva and exposing the sclera.
