a–f Sequence of events in the porcine eye experiment. a Core vitrectomy before patency of balanced salted solution (BSS) flow through the sclerotomy. b The thermocouple measuring the sclera temperature to confirm levels higher than 31 °C. c Fluorescein dye injection in the infusion line before the adhesive placement for a better visualization of the BSS flow through the sclerotomy. d Removal of 50 % liquid poly-N-isopropylacrylamide (PNIPAM). e PNIPAM application on the 20-gauge sclerotomy site. f BSS leakage through the sclerotomy wound at 80 mmHg bottle height
