PurposeThe purpose of this study is to determine whether ReSure hydrogel sealant is superior to standard suture for closure of clear corneal incisions in the setting of combined glaucoma procedures.SettingGlaucoma Department, Duke University Eye Center.DesignThis is a retrospective case series. Subjects studied were patients in a 6-year period undergoing combined phacoemulsification and glaucoma surgery. All cases were performed by the same surgeon. Wound closure methods correlated with discrete timeframes, as ReSure replaced suture midway through the study period, thereby establishing sutured closure as an analogous control group.MethodsAll cases included a phacoemulsification procedure requiring a 2.4 mm clear corneal incision. Upon completion of the phacoemulsification portion of the case, the wound was closed with either ReSure hydrogel or standard 10–0 suture closure. The researchers assessed the rate of Seidel-positive corneal wound leak on postoperative day one.ResultsIn all cases employing ReSure, no wound leak was observed at postoperative day one. Within the suture group, 3 cases showed Seidel positivity of the corneal incision. This equates to a statistically significant difference in wound leak frequency of 2.04% (P = 0.012); confidence interval, 0.21 to 5.82.ConclusionReSure was able to maintain closure 100% of the time over hundreds of combined cases. Suture, though the standard of practice, did not perform to this level, presenting with 3 cases of spontaneous wound leak. We conclude that ReSure is highly effective and superior to suture in closure of clear corneal incisions in combined glaucoma procedures.
