Polyglycolic acid, synthetic, absorbable braided suture was compared to gut with respect to handling, strength, and tissue reaction in 70 strabismus procedures. This new suture material produced less tissue reaction than gut and had handling characteristics that were similar to silk. It can be used in smaller sizes than gut because of its greater strength and firm knot. Polyglycolic acid suture appears to be a useful addition to ophthalmic suture materials.
