Biomechanical testing of a modified knotless transscleral suture fixation technique: an ex vivo study.

ABSTRACT:

Background

To investigate the safety and effectiveness of a modified transscleral suture through ex vivo tests.

Methods

Ex vivo tests were performed in full-thickness porcine scleral pieces using modified knotless transscleral zigzag-shaped suture (Z-suture) fixation technology. The minimum traction force required to loosen or rupture the suture was assessed. The effects of different polypropylene sutures (10-0, 8-0), different suture spans (2.0, 3.0, 4.0 mm), different passes (3, 4, 5 passes), and scleral grooves were investigated.

Results

The average minimum traction forces required to loosen 10-0 polypropylene sutured for 3.0 mm with a suture span of 3, 4, and 5 passes, were 0.18 (0.15-0.18), 0.22 (0.21-0.22), and 0.37 (0.37-0.37) N, respectively. The
