Studies on the tolerance of silk, nylon, dacron and collagen suture material in the cornea of the rabbit.

With rabbit corneas we did comparative biomicroscopical and histological investigations on material tolerance of the following threads at present used in microsurgery: Barraquer silk (virgin silk), nylon 30 mum (Tübinger nylon), dacron (polyester) 40 mum and plain collagen 7-0. The sutures were implanted into the cornea intra-lamellarly, completely under the microscope. The examinations showed only very little tissue reaction in all these materials.
