    Cataract/Anterior Segment

    Dr. Rohit Om Parkash demonstrates how he managed a case of positive pressure during cataract surgery. During irrigation and aspiration, the anterior chamber shallows, and to avoid posterior capsular rupture, the surgeon injects viscoelastic to deepen the anterior chamber. Following insertion of an IOL, however, the iris begins to prolapse through the main port. Dr. Om Parkash injects air through the side port in a slow and laborious attempt to deepen the anterior chamber again. After ruling out a suprachoroidal hemorrhage, he places the patient on 200 ml of intravenous mannitol prior to cortex removal to finish the surgery.
