METHOD FOR FIXING OF POSTERIOR CHAMBER INTRAOCULAR LENS (IOL) AT THE INSUFFICIENCY OF LENS LIGAMENTOUS-CAPSULA APPARATUS

摘要

The method for fixing of posterior chamber intraocular lens (IOL) at the insufficiency of lens ligamentous-capsula apparatus consists in the sutural fixing IOL. One supporting element IOL is fixed by suture to the iris, and other - by suture to the sclera. For this purpose in a point conformed 5 hours, the puncture is made through the corneas peripheral by the atraumatic needle with a nylon filament. The needle is administered through the interior chamber, iris and is lead in a back chamber the parallel to the iris posterior surface, then it is lead out in a reverse order through iris, interior chamber and cornea peripheral part in the distance of 3-4 mm from the place of prick. The microretractor is administered through the tunnel cut of cornea at first in interior chamber and then, through a pupil, - in a posterior chamber. The loop of nylon filament is taken in a point, which corresponds to 5 hours, and it is lead out through the pupil and tunnel cut outside. The lower supporting element IOL is put into the filament loop from the outside of eye and loop is tightened in a knot. The second nylon filament is bound in a knot with free ends on the superior supporting element IOL. The soft IOL is flexed by two pincers and is administered through the tunnel cut and pupil in the posterior chamber. The paracentesis is made in a point, which corresponds to 11 hours, near the tunnel cut in the limb scleral part. Then the basal microiridoectomy is carried out, the microretractor is administered through it in the posterior chamber to the pupil area, the ends of upper filament are taken and lead outside through the posterior chamber,basal colobomf and paracentesis, and fixed by the knot on sclera. The ends of lower filament are tied by knot on the iris by the method of closed iridoplasty.
