Laboratory tests of a substance called GelCORE have shown that it not only helps to regenerate corneal damage, but also promotes the growth of new tissues. The glue is made from chemically modified gelatin and molecules that are activated by blue light. The main function of the cornea is to focus the light. Initially, the glue is transparent and liquid, but when exposed to light, the material hardens, acquiring the natural structure of the cornea. Over time, the cornea cells gradually grow into the material, bind to it and restore the damaged tissue. According to scientists, the properties of GelCORE can be precisely controlled by varying the concentration and exposure time of the light. This makes it possible to change the formulation of glue for different types and degrees of eye injuries. It is worth noting that the use of blue light during treatment is safe, because blue light, unlike ultraviolet rays, does not cause cancer.
“We hope that this biomaterial will be able to fill a significant gap in the treatment of corneal injuries,” says Professor Reza Dana. The glue developers are planning to begin human trials over the course of a year.
