“…These findings may be suggestive of a delayed-hypersensibility reaction (type 4). 6 Similar cases of possible toxic/allergic reaction to nylon have been reported, 2,3,6 although nylon is considered a nontoxic material. 7 Hypersensitivity reactions to suture materials are rare and have been mostly associated with chromic catgut and silk.…”

“…1 Despite nylon's relative inertness, cases of presumed suture toxicity following use of nylon sutures in uncomplicated cataract surgery and vitrectomy have been reported. 2,3 We present the case of a patient with a documented adverse reaction to nylon sutures following glaucoma surgeries in whom nonabsorbable polypropylene (Prolene) suture (Ethicon Inc, www.ethicon360.com) was used during Boston Keratoprosthesis type 1 (KPro) surgery.…”

SummaryToxic reaction to nylon following uncomplicated cataract surgery and vitrectomy has been documented in the literature. We report the case of an aniridic patient with a known adverse reaction to nylon in whom Prolene suture was used in Boston Keratoprosthesis type 1 (KPro) surgery. During follow-up the cornea was checked for signs of inflammation and toxic reaction; at last follow-up (18 months) the patient showed no signs of complications due to Prolene. Our study suggests that Prolene suture may be used as an alternative to nylon in Boston KPro surgery in patients with a history of nylon toxicity.

“…Moreover, the possibility of eliminating or reducing sutures when closing larger incisions using the laser-welding procedure could help minimize adverse reactions from suture toxicity. 11 Objective observations and Seidel tests, especially in eyes with ECCE performed using a 1-plane vertical incision, indicate that sealing the laser-welded wound edges was fully maintained throughout the follow-up. This outcome may be important in practical surgery because quick closure of a wound preserves its integrity and protects it from external pressure (eg, eye rubbing or blinking).…”

“…It has been proposed as an alternative technique or adjunct to conventional suturing procedures to reduce the typical inflammatory processes, such as foreign-body reaction after the application of sutures, as well as to facilitate suturing under certain surgical conditions. 10,11 Many reports of laser-assisted welding techniques mention the possibility of performing effective tissue closure with minimum side effects and improving the healing process. In ophthalmology, experimental studies of laser-induced sealing of corneal tissue in animal models, based on direct absorption of near-infrared and farinfrared laser light by the water content of the cornea, have been reported since 1992.…”

Aims/Background-Interrupted corneal sutures are used routinely by many cataract and corneal surgeons. A slim compact knot facilitates burial and allows atraumatic suture removal, with decreased risk of wound dehiscence. The size and morphology of knots tied in different configurations were investigated. Methods-10-0 nylon suture material was used to tie knots on porcine corneal cataract sections using 2/1/1 (reef and granny), 3/1/1, and 1/1/1/1 (slip knot) configurations. 10-0 Mersilene was used to tie 2/1/i reef knots. Scanning electron micrographs of the knots were digitised and their maximal lengths and widths estimated. In addition, the area of each knot was calculated and used as an index of its volume. Results-21111 reef knots were significantly smaller in all dimensions compared with the other knots (all p<0.03) except for the maximal width of 2/i/l granny knots which were no wider than the 2/i/l granny knots. The Mersilene knots were larger than the nylon ones. Conclusion-The use of 2/i/l reef knots is recommended for corneal suturing. (Br_' Ophthalmol 1996; 80: 164-167) Materials and methods Corneal sections were performed on porcine eyes by a single surgeon (CSCL), and sutured using interrupted monofilament sutures. The sutures used were 10-0 nylon (Alcon Laboratories UK, Watford) and 10-0 polyester (Mersilene; Ethicon). The suture knots were then buried into the cornea, cut and removed, and mounted in a similar orientation for scanning electron microscopy. Four different knot configurations with the nylon monofilament were assessed: a 2/1/1 reef (square) knot, a 2/1/1 granny knot, a 3/1/1 reef knot, and a 1/1/1/1 slip knot, and five examples of each type of knot were examined in order to reduce variability. Five knots were tied using the 10-0 Mersilene in a 2/1/1 reef knot configuration.Following scanning electron microscopy, the knot micrographs were digitised on a digitising tablet by a masked observer (WYC) and estimations of their size calculated. For each knot the maximal knot width at 90 degrees to the suture orientation in the cornea, and the maximal length along the suture were measured, as well as knot area. All knots were scanned at the
