Surgical expertise, prolonged surgical time, suture-related problems, and delayed intraocular lens (IOL) subluxation or dislocation due to broken sutures are limitations of suture fixation of the capsular bag to the scleral wall. We describe a new device made of IOL haptic material (polyvinylidene fluoride) that allows sutureless fibrin glue-assisted transscleral fixation of the capsular bag to address these issues. The device has a hemi-ring portion that lies in the capsular fornix and a double scroll mechanism that engages the capsulorhexis rim. The scroll extends forward as a haptic that is exteriorized through a sclerotomy under a lamellar scleral flap and tucked into a scleral tunnel. The flap is closed with fibrin glue. The device is used for subluxated cataracts and IOLs. It anchors the capsular bag to the sclera, giving vertical and horizontal stability, while providing fornix expansion and allowing stabilization of the bag intraoperatively and postoperatively. The device has been used in 4 patients who had good intraoperative and postoperative courses over a 5-week period.
缝线固定囊袋至巩膜存在手术技术要求高、手术时间长、缝线相关问题、缝线断裂导致的人工晶状体(IOL)半脱位或脱位等局限性。我们介绍了一种由 IOL 襻材料(聚偏二氟乙烯)制成的新装置,该装置可采用免缝线纤维蛋白胶辅助经巩膜固定囊袋,以解决这些问题。该装置具有一半环形部分,位于囊袋穹窿部,以及双螺旋机构,与囊袋切缘相接合。螺旋向前延伸为襻,通过板层巩膜瓣下的巩膜切开术将其引出,并将其塞入巩膜隧道。瓣用纤维蛋白胶关闭。该装置用于半脱位白内障和 IOL。它将囊袋固定于巩膜,提供垂直和水平稳定性,同时扩张穹窿,为术中及术后囊袋稳定提供条件。该装置已用于 4 例患者,在 5 周的时间内,患者的手术过程和术后恢复均良好。
