Cambridge Polymer Group’s team of hydrogel scientists are developing a hydrogel that can be injected as a liquid through a fine needle or cannula, and then gels in the eye. This hydrogel will assist in keeping the retina attached to the back wall of the eye, and will then degrade over time, obviating the need for a second surgery. The hydrogel should also allow vision through the eye while it is in place, resulting in greater patient mobility and compliance.
