METHOD FOR REMOVING IRIS-CILIARY NEW GROWTHS Russian patent published in 2015 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: superficial scleral flap is cut out at a depth of 350 mcm in the form of a rectangular pedicle flap with a pedicle used as a flap base and perpendicular to a limb, whereas one of lateral sides of the flap extends along the limb. After the flap is separated and bent towards the pedicle, a deep scleral flap is formed which is cut out and removed; the formed flap is 0.5 mm lengthwise and 0.5 mm edgewise less than the superficial flap; the lateral side of the deep flap extending along the limb is formed by attaching a portion of Schlemm's canal extending within the growth to the deep flap tissues. To this effect, after forming a side of the deep flap opposed the base of the flap and the lateral side opposed the limb, an anterior chamber is opened at a border of the limb incision alongside of the tumour; viscoelastic is introduced into the anterior chamber; then a dissector knife is used to enlarge the anterior chamber approach at the level of the formed superficial flap by separating the limb tissues in the iris cavity above the trabecule within the flap length, which is followed by dissecting the deep scleral flap completely and removing it. Through a paracentesis made in a sector opposite the surgical site, the viscoelastic is delivered behind the iris thereby providing the iris root protrusion together with the tumour in the formed scleral approach; thereafter the protruding iris tissue is notched within the intact cells; the iris tumour is first to be dissected away, and then after the mobilised iris tissue is pulled on towards the fornix, the ciliary body tumour is dissected away. The tumour is removed; the superficial scleral flap is placed onto the scleral step formed after the deep scleral flap is removed; it is fixed with single interrupted sutured started from the side opposed the base of the flap; the incision is further closed along the limb, which is followed by closing the opposite limb.

EFFECT: method enables reducing postoperative complications and a probability of recurrent new growths.
