Researchers have developed a reversible eye glue that can be used in the field to treat eye injuries by preventing the eye's vitreous gel from leaking out.
The gel, called Poly(N-isopropylacrylamide), or pNIPAM, is non-adhesive in its normal state but will become sticky when subjected to body heat—such as being applied to the eye. Once it has been carefully placed on the wounded eye, the gel will seal the wound to minimize damage and protect the eye's fluids. When the patient arrives at the hospital, personnel can remove the gel with an application of cool saline solution, which causes the gel to revert back to its non-adhesive state.
