ONLINE COVER A Smart Sight-saving Surgical Sealant. In this artistic rendering we see a scleral trauma to the eye treated with a thermoresponsive hydrogel. Bayat et al. developed a synthetic polymer-based hydrogel that could be used as a temporary surgical sealant. The injectable sealant gelled at body temperature and was easily removed upon exposure to cold water. The hydrogel was as strong as cyanoacrylate (super glue), maintained intraocular pressure in open globe injuries in rabbits, and did not provoke excessive inflammation. With its reversible nature, this smart hydrogel could be a temporary solution to seal eye—or other—injuries, preventing progressive tissue damage until further surgical intervention.
