Scientists develop color-changing gel to enhance cataract surgery safety

Scientists at Johns Hopkins have developed a new hydrogel that changes color during cataract surgery. This gel turns fluorescent green under blue light, helping surgeons confirm its complete removal, which can prevent complications like increased eye pressure and vision loss. Previously, surgeons relied on clear gels that could be left behind, risking patient safety. The new gel bonds a fluorescent dye to its structure, ensuring visibility without leaking into the eye. This innovation aims to enhance the safety and efficiency of cataract and other eye surgeries. While the gel has shown promise in animal tests, human trials are still needed. Researchers are working on scaling production and optimizing dye concentrations for clinical use.
