title: [Standardized wound construction for no-stitch cataract surgery with maximal incision to 11 mm. Experimental and clinical results].
abstract: We use the trapezoidal lamellar incision as standard construction for sutureless self-sealing wound closure in our clinic: a 7 mm incision for phacoemulsification and implantation of a 6.5 mm optic diameter PMMA posterior chamber less (PCL) and an incision up to 11 mm for ECCE with standard PCL. The operation can be performed in a nearly closed system because of the self-sealing wound construction. Experiments in cadaver eyes showed that the wound closure of a 7 mm incision with the no-stitch technique ruptured at a pressure five times greater than the cross-stitch-sutured corneoscleral incision and in an 11 mm incision four times greater (602 +/- 149 mmHg and 150 +/- 29 mmHg). Due to the high stability of the wound closure, no sutures are necessary. Complications arising in connection with sutures are therefore avoided. Clinically, two typical postoperative complications were observed: hypotony occurred in 1% and anterior chamber hemorrhage in 5%. These complications are exclusively caused by imperfection of the internal corneal opening.
