title: Hydrogel sealant versus sutures to prevent fluid egress after cataract surgery.
abstract: OBJECTIVE
  To evaluate the effectiveness of a hydrogel sealant versus a suture in preventing fluid egress after wound leakage in cataract surgery.
  
  
  METHODS
  Twenty-four ophthalmic clinical practices in the United States.
  
  
  METHODS
  Prospective randomized parallel-arm controlled multicenter subject-masked study.
  
  
  METHODS
  Healthy patients having uneventful clear corneal incision (CCI) cataract surgery were eligible for the study. Spontaneous and provoked fluid egress from wounds was evaluated at the time of surgery using a calibrated force gauge. Eyes with leakage were randomized to receive a hydrogel sealant (Resure) or a nylon suture at the main incision site. Incision leakage was reevaluated 1, 3, 7, and 28 days postoperatively.
  
  
  RESULTS
  Of 500 eyes, 488 had leakage at the time of cataract surgery. The leak was spontaneous in 244 cases (48.8%), and 488 (97.6%) of all incisions leaked with 1.0 ounce or less of applied force. After randomization, 12 (4.1%) of 295 eyes in the sealant group and 60 (34.1%) of 176 eyes in the suture group had wound leakage with provocation (P<.0001). The overall incidence of adverse ocular events was statistically significantly lower in the sealant group than in the suture group (P<.05).
  
  
  CONCLUSIONS
  In this study, 97.6% of CCIs leaked after cataract surgery. The hydrogel sealant was safe and effective and better than a suture for the intraoperative management of CCIs with leakage as seen on Seidel testing and for the prevention of postoperative fluid egress.
