although the name "vicryl" is a trademark of ethicon, the term "vicryl" has been used generically referring to any synthetic absorbable suture made primarily of polyglycolic acid. other brands of polyglycolic acid suture include polysyn, surgicryl, polysorb, and dexon, all of which are manufactured by different companies. vicryl is a copolymer of lactide (a cyclic diester of lactic acid) and glycoside. in practice, vicryl comes braided, dyed or undyed with the following decay schedule: 75% at two weeks, 50% at three weeks, and 25% at four weeks (i.e., the sutures retain that proportion of tensile strength at those dates).

in this procedure, a triangular partial thickness scleral flap is created using a diamond knife. the scleral flap is then extended to the limbus that is hinged anteriorly. a sclerotomy is then made with a punch followed by a peripheral iridectomy. an 8-0 nylon suture is then passed through the conjunctiva from the external aspect into the subconjunctival space. this process creates the cheesewiring effect. the needle is entered 3 mm from the lateral edge of the future bleb site and 3-4 mm away from the limbus. the 8-0 nylon suture is taken under the scleral flap. once this happens, the suture is reversed and the needle is passed through the conjunctiva from the inside towards the outside position. a singular 10-0 vicryl suture can secure the scleral flap and then the cheesewire suture can then be cut flush to the conjunctiva. the conjunctiva flap can be then secured with 26 10-0 vicryl sutures at either end of the limbus. a single 10-0 vicryl mattress suture can be placed in the middle. this entire process allows for blebs to be rescued .
