title: Bursting point of sutured limbal incisions.
abstract: The bursting point of standard limbal cataract incisions closed with five or 11 sutures was measured in postmortem eyes with an air gauge and bulb. Bursting point was a minimum of 90 mm Hg when five sutures of either 7-0 polyglactin 910 or 10-0 nylon closed the incision. Eleven sutures increased the average bursting point 55% for nylon and 87% for polyglactin 910. Bursting point was higher for flat than watch-glass-beveled incisions. Wound leak always occurred at pressures well below the bursting point.
