Specialists from the University of Southern California are working on creating such an adhesive gel. Initially, it was intended for soldiers with eye injuries who were unable to quickly receive qualified medical care. However, this useful development will find application in peaceful conditions – it will soon become available to everyone. The essence of the method is as follows: a temperature sensitive gel is applied to the wound site of the eyeball and completely closes the wound. The liquid gel is applied chilled to the eyeball, in contact with it its temperature rises, and due to its adhesive properties, it becomes viscous and freezes, reliably isolating the eye from the external environment and infection. It is washed off with cold water, at which it again becomes liquid. The PNIPAM hydrogel, adapted for use on an eyeball, was a prototype of development. The new gel can not only reduce the time of subsequent treatment, but also help to save the eye. To cool the hydrogel, a syringe is used, specially designed for this and playing the role of a kind of refrigerator due to the presence of crystals of calcium ammonium nitrate. To obtain glue for the eyes, a hydrogel is mixed with water in such a syringe, and after 20-30 seconds it acquires its unique properties. Until now, experiments have been carried out on rabbits, but clinical trials will start in 2019.
