This study discusses a synthesis route for soft polysiloxane-based urea (PSU) elastomers for their applications as accommodating intraocular lenses (a-IOLs). Aminopropyl-terminated polydimethylsiloxanes (PDMS) were previously prepared via the ring-chain equilibration of the cyclic siloxane octamethylcyclotetrasiloxane (D4) and 1,3-bis(3-aminopropyl)-tetramethyldisiloxane (APTMDS). Phenyl groups were introduced into the siloxane backbone via the copolymerization of D4 and 2,4,6,8-tetramethyl-2,4,6,8-tetraphenyl-cyclotetrasiloxane (D4).

We present the case of an 83-year-old patient who underwent cardiac surgery and developed postoperative non-occlusive mesenteric ischemia (NOMI), which was treated with a local intra-arterial papaverine and prostaglandin E1 infusion. After successful mesenteric reperfusion, a multiple organ dysfunction syndrome with severe cardiovascular failure developed. High norepinephrine dosages (1.
