    Dr. Michael Snyder demonstrates how a vitrector can be used to reconstruct the iris. In a case of inferior coloboma, he uses a 23-gauge vitrector to carve the superior margin after closing the inferior defect with a suture. Dr. Snyder also uses the vitrector to create a circular aperture for a teardrop-shaped pupil, and to assist in trimming strands of necrotic iris tissue in a case of iridoschisis. Finally, he demonstrates that a 27-gauge vitrector can offer a refined and safe way to carve a pupil.
