FIELD: medicine.
SUBSTANCE: after 5 mm long conjunctival incision, sclera is cut to 1/3-1/2 of its thickness concentrically with the scleral sulcus, at three meridians at an equal distance from each other, in 3 mm from the scleral sulcus with base direced thereto to form the entrance to three scleral pockets. The sclera is exfoliated to produce pockets. A tunnel corneal 2.2 mm wide incision is performed. ILO consisting of a circular optical portion of a positive lens and the colored haptic portion formed as a ring is implanted concentrically with the optical portion. The haptic part is further provided with three elastic supporting members, arranged at the same distance from each other, each of them has the form of spear. Thus, ILO implantation is performed through the cartridge and injector into the anterior chamber. Using 25G vitreous tweezers, each of the spear-form supporting members are placed in the appropriate scleral pocket.
EFFECT: method provides stable central position and secure ILO fit, allowing to reduce the risk of intraoperative bleeding and postoperative complications due to hypertension, eliminate the cosmetic defect of aniridia, improve intraocular fluid circulation while increasing the strength of the artificial iris.
