Certain conditions have been found to hasten the breakdown of absorbable PDS (polydioxanone) sutures. It is important that surgeons handle the sutures carefully to avoid premature breakdown.

In a series of cataract operations with a corneal incision PDS 10-0 absorbable sutures were tested. In contrast to deeper PDS sutures, such as are used in corneoscleral incisions, the corneal sutures opened as early as between 13 and 30 days postoperatively in 5 out of 7 cases. Postoperative irritation was more severe and lasted longer than is usual when non absorbable sutures are used. This was probably caused by ends of the thread which had not yet been absorbed, resulting in a foreign body irritation of long duration. Altogether, absorbable PDS 10-0 sutures are only suitable for corneal wound closure to a limited extent.

PDS (Polydioxanone suture), a new synthetic absorbable suture, was used in experimental and clinical trials. The experiment was performed on 14 rabbits anesthetized with intravenous sodium pentobarbital. Five months were needed for complete absorption of a piece of PDS left in a tunnelled corneal stroma. As late as the end of the second month no histological absorption was detected. This was twice as long as that persistence of polyglactin sutures studied under the same experimental conditions. In another series of 12 animals, the PDS suture was placed in the central cornea and tied with a buried knot. The PDS suture broke four to six weeks postoperatively in the superficial part of the cornea. The histologic tissue reaction in both these studies was minimal, resembling that obtained with black 10/0 monofilament nylon. In the clinical study, PDS sutures were used (size 0.2 metric and 0.3 metric) in 38 cases of cataract extraction. The material was easy to handle, especially when dyed violet. No side-effects attributable to the suture material were observed. PDS retained its tensible strength longer than other absorbable sutures, but can be used only for closing limbal incisions with conjunctival flaps in order to prevent tear hydrolysis of the suture.

PDS (polydioxanone suture), a new synthetic absorbable suture, was used in 21 patients undergoing cataract surgery. It still retains 25% of its tensile strength at 42 days but absorption takes 130-180 days. 1 braided coated and 1 monofilament PDS were adequate as conjunctival sutures but offered no advantage over available materials. 0.5 monofilament PDS was superior in handling qualities to 0.4 virgin silk. It does not need to be removed but retains tensile strength for longer than other absorbable sutures.

This study describes the intraoperative and postoperative performance of 9-O monofilament Polydioxanone (PDS) suture for cataract wound closure. This newly developed synthetic absorbable suture is designed to meet the need for a "long-term" absorbable suture material suitable for cataract wound closure following intraocular lens implantation. Polydioxanone's advantages over currently used "short-term" absorbables and biodegradable nylon are described in this report.
