Biological networks are often extremely complicated structures, often made of ordered arrangements of biopolymers. These structures can suffer damage or Persistence Diagrams to Visualise Damage to Biological Networks degrade over time, with serious consequences for the functionality of the network and the organism containing that network. It is important to understand the precise nature of damage over the lifespan of a network; a better understanding of how defects or tears propagate over time could be used to inform methods to either halt or repair the damage. One such biopolymer network of scientific interest that loses function over time is that of collagen in the ocular lens capsule. The loss of flexibility owing to damage-induced changes in the lens capsule has consequences for the visual system losing its ability to accommodate different focal depths ), or the lens capsule can suffer immediate damage when ruptured during cataract surgery ) or by exposure to focussed high energy sources.
