Vicryl is a copolymer of lactide (a cyclic diester of lactic acid) and glycolide (a cyclic diester of glycolic acid). 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).
The PDS suture knots must be properly placed to be secure. Conjunctival and vaginal mucosal sutures remaining in place for extended periods may be associated with localized irritation. Subcuticular sutures should be placed as deeply as possible in order to minimize the erythema and induration normally associated with adsorption.
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. [5]
A #4 suture would be roughly the diameter of a tennis racquet string. The manufacturing techniques, derived at the beginning from the production of musical strings, did not allow thinner diameters. As the procedures improved, #0 was added to the suture diameters, and later, thinner and thinner threads were manufactured, which were identified as ...

Surgical suture on needle holders. Catgut suture in a vintage glass dispenser.
