Iris Fixation via External Pentagram Suturing
0 Views •
2022
The present protocol describes how a 10-0 polypropylene suture crosses the anterior surface of the iris, forming a pentagram to prevent both iris and pupil from moving toward the cornea. This can be combined with subsequent keratoplasty to cure bullous keratopathy with extensive anterior synechia of the iris.

Our goals were to design, manufacture and test ferromagnetic stents for endothelial cell capture. Ten stents were tested for fracture and 10 more stents were tested for retained magnetism. Finally, 10 stents were tested in-vitro and 8 more stents were implanted in 4 pigs to show cell capture and retention.
FAQs
Failure mode shows how the repair loses fixation, rather than reporting force alone. A specimen may allow the suture to pull through, or the suture itself may break. Distinguishing these outcomes helps identify whether performance is limited by anchoring in the tissue or biomaterial, or by the suture and its construction, guiding more informative comparisons among repair materials.
Peak force provides a quantitative indicator of the maximum load the fixation withstands before failure. Higher values can support comparisons of repair strength, but interpretation should remain connected to the observed failure mode. A strong result caused by thread breakage differs mechanically from one in which the suture pulls through the specimen, so both measurements are needed.
The method can distinguish performance among suture designs, needle and thread combinations, tissue substitutes, and engineered grafts. Testing these options under the same loading approach creates a basis for comparing fixation performance rather than relying only on design descriptions. Such comparisons can reveal which combinations provide stronger anchoring for a particular soft-tissue repair strategy.
A typical workflow places the suture through a standardized tissue or biomaterial specimen, applies controlled tensile loading, and continues the test until the suture pulls through or breaks. The peak force is then recorded alongside the failure mode. Together, these outputs characterize how securely the repair configuration withstands mechanical loading and enable comparisons across candidate materials.
Researchers use it when evaluating whether a tissue substitute or engineered graft can provide adequate fixation for soft-tissue repair. The results help compare candidate suture systems and repair configurations before selecting materials for further development. Because the test directly examines anchoring under tensile load, it supplies mechanical evidence relevant to wound-closure and graft-fixation strategies.
By quantifying peak force and documenting how failure occurs, the test supplies evidence for judging repair strength and fixation performance. Bioengineers can use those outcomes to compare material and suture configurations, identify weaker anchoring behavior, and refine designs for tissue substitutes or engineered grafts. This supports development of surgical materials intended for safer wound closure and soft-tissue repair.
