Evaluation of the materials properties used for the production of surgical threads during the simulation of use in eye microsurgery.

Purpose: The aim of this study was to evaluate absorbable and non-absorbable surgical sutures exposed to an environment with a chemical composition similar to that of ocular body fluids. Methods: The evaluation was based on the results of tests of the mass, diameter and mechanical properties of samples immersed in physiological saline solution (BSS) at different time intervals. Results: Based on the conducted research, it was found that multifilament threads made of PGCL dissolve the fastest under these conditions, while PDS monofilament threads dissolve the longest. In the first case, the last measurements could be taken after 14 days of immersion, while in the second case, the mono-filament was not completely dissolved even after 80 days. Conclusions: Despite numerous publications in this area, available from various sources, it is very difficult to compare the obtained results to those of other authors. This is due to the fact that studies conducted on threads made of different materials and diameters, as well as in different environments, can have a significant impact on the resorption process. This justifies the need for this type of research.
