The evaluation of 7-0 Polyglactin 910 suture in cataract surgery.

The new synthetic absorbable suture, Polyglactin 910, represents a significant step toward absorbable suture perfection. In 218 cataract surgical procedures, the performance of Polyglactin 910 was compared to that of Chromic Catgut and Chromic Collagen. The results obtained in this series of cases is the basis for this article. When compared to Chromic Catgut and Chromic Collagen, Polyglactin 910 consistently provided greater tensile strength, improved handling, significantly decreased tissue reaction, more batch-to-batch uniformity, superior wound tensile strength retention, and a predictable absorption rate that is virtually completed in 35 days. Both nonprotein and nonantigenic, Polyglactin 910 evoked less tissue reaction and proved more versatile and reliable than either of the other sutures.
