[A method of closed iridoplasty in transparent crystalline lens]

The operation is performed through two punctures of the cornea with the normal depth of the anterior chamber artificially maintained with physiologic saline supplied via a flat cannula. Through a corneal puncture this cannula is brought under the contralateral edge of iridal defect, elevating this defect beyond the lens, and a needle brought via the other puncture pricks the iris and the needle tip enters the cannula canal. The needle and cannula joined together are brought to the second edge of iridal defect, similarly pricking it, and brought out of the anterior chamber, still joined together. Then the needle is brought back through the same corneal puncture, so that it joins the cannula brought through the other corneal puncture, and brought from the anterior chamber. The stitch is tied on the cornea, with the iris being tightened.
