    Zonular Dialysis with Ahmed Capsule Tension Segment

    Cataract/Anterior Segment

    This video features the MST capsule retractors, which have a unique design intended to reduce the chance of tearing the capsulorhexis or puncturing the equatorial region of the capsular bag. Dr. Chang illustrates the need to adjust the tension of the retractors to avoid overly stretching or tearing the capsulorhexis as the entire bag is posteriorly displaced by the hydrostatic force of the phaco tip infusion. Because the entire capsular bag tends to tilt posteriorly in the quadrant of zonular disruption, an Ahmed Capsular Tension Segment (CTS; FCI/Morcher) is implanted and scleral fixated with a 9-0 Prolene suture. The traumatic mydriasis is repaired with the 2-interrupted-sutures cerclage technique.
