Proper positioning of the patient for cataract surgery is important for the comfort of the patient and the surgeon, but more importantly for safety and ease during surgery. With the head in proper position, the iris should be parallel to the floor of the operating room. This keeps the eye in good alignment for the surgery with a better view and easier access to the tissues.
With the chin down position, the tilt of the iris can make surgery more difficult. The patient can help by looking at the microscope light, but remember that this is the patient’s up-gaze and that is more limited in range than down-gaze or lateral-gaze.
